Can I change the trim (showerhead, arm, flange, escutcheon, handle/knob and tub spout) without changing the valve in the wall?

Replacing the trim on an existing Moen tub/shower can be accomplished by first determining what kind of valve is in the wall. For many years Moen tub/shower valves have been manufactured using one of three valves. These valves are Standard, Posi-Temp and Moentrol. Although the look is similar, the trim is not necessarily interchangeable.

To determine if the trim can be changed without changing the valve in the wall, the first step is to identify what type you have. This chart(section) shows the differences.

Note:Posi-Temp trim and Moentrol trim are not interchangeable.

Figure 1 shows that the screw holes at the 5:00 and 7:00 position. This is a Standard valve that features a pull on/push off operation and turns left and right for hot and cold.

Figure 2 illustrates the pressure balanced valves. Models that have a lever or knob that rotate only are called Posi-Temp. This "cycling valve" handle is pointed towards the 6:00 position when off, rotates to the 3:00 position for cold, 12:00 for warm and 9:00 for full hot. If this is the way your Moen valve operates, any Posi-Temp trim will fit.

The other valve mentioned in Figure 2 is Moentrol. Moentrol is also pressure balanced and includes the pull on/push off volume control feature. The screw holes are at the 2:00 and 7:00 position. If your valve operates this way and has these screw hole locations, any Moentrol trim will fit.

A recent innovation now makes it possible to retrofit round Moentrol trim to standard valves. Service kit number 145058 (shown below) can be ordered to make the change.

Shower arms are usually threaded into an elbow behind the wall. Rotate the shower arm counterclockwise to remove. The new shower arm and shower head should be sealed using several wraps of thread seal tape. The shower arm flange is usually sealed by using Plumber's putty.

The final consideration is the tub spout. Moen makes two versions. The IPS (Iron Pipe Size) version (below left) is threaded and screws onto a ½" pipe that has male threads.

The other style is the slip fit tub spout (above right). It attaches to ½" copper tubing by slipping on and tightening with a hex wrench. Both tub spouts will have a cut out on the underside near the wall as shown above. If the cut out has a place to insert a hex wrench, you have a slip fit. If the cut out does not have the hex wrench opening, your spout is a threaded (IPS) version.

Why does my PosiTemp® shower, with waterdrop knob, only give me hot water or cold water, and not a mixture?

In most cases, the knob has been installed upside down. To correct this simply:

  1. Remove handle cap and the Phillips screw under the cap.
  2. Pull the handle off the faucet.
  3. Now replace the handle, only this time, make sure the point of the waterdrop handle is pointing downward to the six o'clock position.
  4. Replace the Phillips head screw and handle cap.

Can I purchase new tub and shower trim and connect it to my existing Moen tub and shower valve?

Yes, if you currently have an existing PosiTemp and/or Moentrol valve. Our trim kits work on Moen's M-Pact system.

What is the M-PACT® system?

MPact Available for both lavatory and tub / shower faucets, M-Pact is a common valve system that allows you to change your trim above the sink, without changing the valve below the sink; making style changes and upgrades quick and easy for you. You can upgrade the style at any point in the decorating or construction process or switch style years down the road without replacing any faucet plumbing.

What is meant by a "pressure-balancing" tub and shower faucet?

A pressure-balancing tub and shower faucet balances incoming hot and cold water pressure to compensate for fluctuations in water flow. Balancing the water flow keeps shower temperatures constant and comfortable, within ±3°F (1°C) of the original temperature, despite other demands such as flushing the toilet or starting the dishwasher. Moen's PosiTemp and Moentrol® tub and shower valves all feature pressure-balancing. Both valves require pressure on the hot and the cold side to operate.

I haven't used my Posi Temp shower in my guest bath in a while. I now only get hot or cold water but not both.

It is possible that the balancing spool is stuck due to non-use. Replace the cartridge to correct this situation. To prevent future issues, use the faucet at least once a week.

What size hex wrench is used to remove my PosiTemp® lever?

A 7/64 hex wrench can be used in most cases to remove the handle set screw. A Phillips screwdriver is then used to remove the handle adapter.

What is the difference between a PosiTemp® tub and shower valve and a Moentrol® tub and shower valve?

While the valves do have several similarities:

  • A pressure-balanced system that maintains water temperature within ±3°F (1°C)
  • Built-in temperature limit stops which allow you to control how far the handle rotates, therefore, controlling the range of water temperature
  • Best water flow for any comparatively priced valve
  • Available in a variety of connections from common ½" CC/sweat, ½" IPS-threaded; ½" PEX or CPVC
  • Meets pressure-balancing safety codes

There are a few differences to consider before making a decision.

Feature Moentrol PosiTemp
Handle Operation – How the faucet is turned-on and off. Pull / Push Rotation
Temperature Memory – When shutting-off the faucet, the handle stays in the exact temperature position you set during use. The next time you turn-on the faucet, within a few seconds, the water temperature reaches your last temperature setting. Yes No
Volume Control – Controls the water flow rate so you get the amount of water you want at the temperature you want. Yes No

Does the Moen Roman Tub valve spout shank need to be cut to the desired height after it has been installed? Does Moen make a shorter one?

The spout shanks for Moen's Roman Tub valves no longer require cutting to height. Models 4992 (for copper to copper connections) and 4993 (for PEX and CPVC connections) now feature an exclusive no cut adjustable shank. Click here to see installation vidoes.

Moen also offers Roman Tub valves with built-in hand shower diverters (4 hole installation). Model 9992 is for copper to copper connections and 9993 is for PEX and CPVC connections.

What is a pop-up drain assembly?

A pop-up drain assembly is commonly used in bathroom sinks. A mechanical plug called a "pop-up stopper" is used to hold water in the sink. Moen offers lavatory faucets both with and without the pop-up drain.

Can I use my existing drain assembly when installing a new faucet?

In most cases, yes. But if you're changing finishes, (i.e.,from chrome to brass), you'll probably want to change the drain assembly to match your new faucet finish.

Can I replace a two-handle lavatory faucet with a single-handle model? Do all faucets fit all bathroom sinks and tub/showers?

Standard-size sink openings and faucet dimensions are used throughout the plumbing industry. However, since there are a few exceptions (such as 4" spread or 8" spread), it is a good idea to check sizes first.

Bathroom Sinks:
Many single- and two-handle faucets are on 4-inch centers, which is the distance between the centers of the hot and cold inlets or mounting bolts. Another popular style for two-handle faucets is the 8" to 16" widespread. These faucets come with flexible hook-ups to allow for adjustments.
The distance between hot and cold water supplies for two-handle faucets is generally 8". The hole opening for single-handle tub/shower combinations may vary. The opening must be smaller than the faceplate of the unit you are installing for proper coverage.

Can I replace a two-handle or three-handle shower valve with a single-handle model?

Yes, Moen remodel cover plates make it easy to replace many two or three handle shower valves with a stylish single handle Our cover plates allow you to keep your existing tile or wall covering intact, and are available in chrome (part 1920), oil rubbed bronze (part 1920ORB), brushed nickel (part 1920BN) and polished brass (part 1920P) finishes. Moen part 1920 works with 7" diameter round Moen escutcheons only.

What makes ExactTemp® better than the competitors' thermostatic valves?

Our ¾" ExactTemp valve allows for multiple shower configurations due to its high volume water delivery system.

What is a Vertical Spa?

A vertical spa is a unique, customizable showering system. Use a combination of body sprays, showerheads, and hand showers to create your own luxurious showering experience.

Why is there a gap between the handle and the escutcheon of my one-handle shower faucet?

There is a gap in this location to ensure the screws on the escutcheon do not interfere with the operation of the handle. Depending in the installation, it is acceptable for this gap to be between ½" to an inch.

Can I replace a two-handle kitchen faucet with a single-handle model?

The answer depends on how many holes you have in your sink. Most two-handle kitchen faucets mount through three or four holes, while one-handle faucets can be mounted through one hole or up to four holes. Depending on the Moen faucet you select, you may have unused holes (i.e. one hole mount faucet replacing a two hole mount faucet). If you have unused holes in your sink, you can fill them with either a cap or soap dispenser.

Our faucets are designed to accommodate standard-size sink openings used throughout the plumbing industry. Generally, the standard distance of a faucet's hot and cold valve connections, for both single and two-handle kitchen faucets, is 8". Sometimes, there are exceptions. It is always a good idea to measure the distance between the hot and cold valve connections on your old faucet before purchasing a new one.

How many holes are necessary in my sink deck to install my kitchen faucet?

Our kitchen faucets come with a wide variety of mounting adaptations. Single-handle faucets are available that mount through 1, 2, 3 or 4 hole applications. Two-handle faucets come in 3 and 4 hole applications. If your existing faucet is covering up the holes, you can look under the sink to see how many you have.

Can I purchase a non-spray faucet and convert it to a sprayer model using my existing side spray?

No, kitchen faucets with hose and sprays have different valve bodies than non-sprayer models.

Can I purchase a spray faucet and convert it to a non-sprayer model?

Yes, kitchen faucets with hose and sprays have a connection for the side spray hose that can be plugged off. Service kit number 143530 can be ordered to disable the side spray.

Can I install a kitchen faucet without a hose and spray in a 4-hole sink?

Yes. You can use a non-spray model faucet, which utilizes 3 holes, and take advantage of the extra hole by using a liquid soap/lotion dispenser or other accessory. The fourth hole can also be capped with a sink hole cover.

I just replaced the cartridge in my Moen kitchen faucet and the handle will not stay in the on position, how do I fix this?

During manufacturing, lubrication (silicone) is used on the cartridge. The combination of lubrication and the weight of the handle can cause the faucet to self-close. This can be corrected in several ways:

If your faucet has a 1225 cartridge:

  1. Make sure all screws are tight.
  2. Remove excess silicone from center stem of cartridge.

If your faucet has a 1255 cartridge - replace the cartridge.

If your faucet has a 4000 cartridge - tighten the cartridge nut or replace the cartridge.

If the faucet has a handle connector:

  1. Change the handle connector.
  2. Check the old cartridge stem for a gray metal washer. This washer must be transferred to the stem of the new cartridge.

My kitchen faucet handle is hard to operate. What can I do to correct this?

For one-handle faucets with a 1225 cartridge, simply remove the cartridge and lubricate it both inside and out with silicone-based grease (Moen part number 99915). Do not use plumber's grade faucet grease, silicon sprays or any lubricant that contain petroleum. Petroleum based lubricants may react with rubber seals and actually cause the faucet to become even more difficult to operate.

For two-handle faucets, we recommend replacing the cartridge. The part number for a two-handle kitchen cartridge is 1224. You can purchase these parts online by visiting our Replacement Part Store.

For one-handle faucets with a 1255 or 4000 cartridge, replace the cartridge.

Does Moen make undermount sinks?

Moen makes a variety of both undermount and drop-in sinks, made from stainless steel, click here to view our sink collections.

What size basket strainers do I need for my new sink?

Basket strainers are typically standard in size and fit most sink openings - 3½" for kitchen sinks and 2" for bar sinks.

Why don’t basket strainers come with new sinks?

Due to the variety of color, style and garbage disposals available, basket strainers are usually sold separately.

How can I find my model number?

Exact model numbers can be found on your box or on your instruction sheet. If unavailable, you may find the general family series number on the back of the spout (non pullout). The series number will not be exact model number, but it will be helpful when used in conjunction with the faucet images shown in our Replacement Part Locator. New faucets may have a model identification tag attached to the supply lines of the faucet.

I have located a number on my faucet, but your website states it is not a model number. What number is this?

This number can be a series number or a component number. A series number will indicate the "series" of faucet, but not the exact number within that series. A component number is used during the manufacturing process, and it will also not indicate your model number. Please view our Replacement Part Locator to determine the model of your faucet.

My faucet has a high-arc spout, and it does not immediately shut off after the handle (or handles) are turned off. Why is this?

This is a normal characteristic of any faucet with a high-arc spout. After the handle (or handles) are shut off, there is still water inside of the spout. Any residual water past the arc of the spout will slowly drip out of the spout. Gravity will pull this water from the spout; however, it should stop after several minutes.

Cleaning & Care

What kind of cleaner can I use on my LifeShine® faucet?

The LifeShine can be cleaned with most household cleaners (including mild abrasives), when used according to the manufacturers' instructions for use. Avoid using any cleaners or pads/sponges that are unsafe for polished metallic surfaces. Most green, fibrous pads or sponges contain microscopic mineral particles that can scratch a faucet's finish, including LifeShine finishes. Cleaner manufacturers may change their formulations at any time; therefore, Moen does not recommend any specific cleanser. Immediately after cleaning your faucet, wash off remaining cleanser with water. To remove water spots, use a soft, damp cloth. We also suggest a periodic application of a quality, non-abrasive wax such as car wax or furniture wax. For faucets with clear knob style handles, cleaners should be approved for acrylics.

What kind of cleaner can I use on non-LifeShine components?

Do not use cleaners that contain abrasives, harsh chemicals, alcohol, or other organic solvents. Avoid using any other cleansers or pads/sponges that are unsafe for polished metallic surfaces. Most green, fibrous pads/sponges contain microscopic mineral particles that can scratch a faucet's finish. Cleaner manufacturers may change their formulations at any time; therefore, Moen does not recommend any specific cleaner. Immediately after cleaning your faucet, wash off remaining cleaner with water. To remove water spots, use warm water and a soft, damp cloth. To preserve the luster of your faucet, occasionally apply a high quality non-abrasive wax, such as car wax or furniture polish. For faucets with clear knob style handles, cleaners should be approved for acrylics.

How do I replace my Moen cartridge?

For single-handle faucets with push/pull action handles, please view our Animated Installation Help for the 1225/1220 cartridge. Step by step instructions are included with all Moen replacement cartridges - refer to the cartridge model that you have.

For two-handle models, please view our Animated Installation Help for the 1224 cartridge.

How do I install my kitchen or bathroom faucet?

For directions, refer to your specific model's installation instruction sheet. You may also try our Animated Installation Tutorials and Installation Videos for more assistance. These tools may help you during your faucet installation:

  • Flashlight
  • Screwdrivers
  • Adjustable Wrench
  • Channel Locks or Pliers
  • Safety Glasses
  • Basin Wrench
  • Flexible Supply Lines
  • Plumbers Putty
  • Silicon Sealant
  • Thread Seal Tape

Consult your faucet's box for a list of required tools.

Will it take me long to install a faucet?

The most time-consuming, and sometimes challenging step, will be removing the old faucet, especially if your water supply connections are corroded (and, therefore, hard to disconnect). By using the installation guide, installing the new faucet, however, should be relatively simple.

Document the model number and retain both your paperwork and receipt for model identification.

What tools will I need to install or fix my faucet?

Before you leave the store with either your new faucet or the replacement part you need, make sure you have these items to help install the faucet or part easily. These items are also listed on the Moen package:

  • Phillips and Regular Screwdrivers
  • Adjustable Wrench (or basin wrench for hard to reach areas)
  • Flashlight
  • Pliers
  • Plumber's Putty (not required on all installations)
  • Thread seal tape
  • Allen Wrench (not required on all installations)

What are "sweat and/or cc fittings" and what does it mean "to sweat a pipe"?

Soldered fittings, also called "sweat fittings," are used to join copper pipes such as those commonly encountered in some in-wall tub and shower applications. Soldering a pipe joint or "sweating a pipe" is accomplished by heating a copper fitting with a propane torch until the fitting is just hot enough to melt metal solder. The heat draws the solder into the gap between the fitting and pipe to form a water tight seal. Soldering requires some skill and attention to safety, but it creates a strong bond when joining copper pipes. Flexible copper tubing can also be joined with compression fittings or flare fittings (these do not require soldering).

Can I join copper to PVC tubing? If so, how?

Yes. Rigid plastic PVC (Polyvinyl-Chloride) tubing can be joined to copper using "grip fittings." Each side of a grip fitting contains a narrow grip ring and a plastic compression ring (or rubber O-ring) that forms the seal.
Useful Tips:

  • Use penetrating oil to help loosen corroded mounting nuts.
  • Use a hacksaw for cutting steel or plastic pipe.
  • Use a basin wrench for those hard to reach areas.
  • Use a tubing cutter to make straight, smooth cuts in plastic and copper tubing.
  • Wrap thread seal tape clockwise around threaded joints to ensure a tight seal.

When do I need to use thread seal tape, pipe dope or plumber's putty?

Thread seal tape and pipe dope are both effective pipe sealants. However, many people prefer using thread seal tape since it is cleaner to work with than traditional grease or paste-like sealants. Plumber's putty is used to form a water tight seal between the sink and the faucet and between the sink and the drain. Some of our models include gaskets making sealants optional. Plumber's putty is not for use on threaded pipe joints or marble surfaces.

I have received some parts to repair my faucet. Is this something that I can repair?

It is impossible to determine if someone will be comfortable performing their own repair on a faucet. Instructions are included with most parts, and it is recommended that those instructions be reviewed. If there are questions regarding the instruction, contact 1-800 718 4345. We can provide answers to your questions, which should help you determine if the repair will be something that you are comfortable with.

What should I look for when purchasing a faucet?

When purchasing a faucet, you should consider quality, features, and style. Moen faucets are a perfect combination of all three!


One-piece Washerless Cartridge Construction – Moen's innovative one-piece cartridge means no washers or springs–the most common causes of leaks. The self-contained assembly has fewer parts meaning greater reliability and worry-free performance year after year.

Moen's Ceramic Disc Design – A revolutionary ceramic disc design provides like-new operation for generations of use. European ceramic disc cartridge technology allows for harsh water conditions.

Moen's 1255 Duralast cartridge – provides a consistently smooth handle feel for the life of the faucet. Turn it on. Turn it off. Every time, the faucet will feel like new and perform like new. Smooth handle movement offers precise control, allowing you to fine-tune temperature balance.

Lifetime Warranty – Moen faucets come with a (Limited) Lifetime Warranty against leaks, drips, and finish defects. (post 1995 to the original home owner)


Pressure-Balancing – We've all been there. The shower becomes instantly scalding hot or ice cold because someone turns on a washing machine or flushing a toilet. Our pressure-balancing Moentrol, PosiTemp, and our thermostatic ExactTemp valves help guard against "shower shock."

LifeShine® Non-Tarnish Finishes – Use it everyday, you will never scrub or wear-off the beauty of a LifeShine finish. It gives you the option of designer finishes with the durability of chrome, and it is warranted not to tarnish, corrode, or flake off…for life.

Our revolutionary M-Pact common valve system allows you to completely upgrade the style of your bathroom sink faucet or your tub and shower faucet without replacing any of the plumbing. You can upgrade the style at any point in the decorating or construction process or switch style years down the road without replacing any faucet plumbing. MPact

Quick Installation – Our products are designed to be installed in a short period of time. Whether you are a plumber or a do-it-yourselfer, installation will be quick and easy.


Buy It For Looks. Buy It For Life® – Moen faucets are built for your lifestyle. Clean and classic or bold and contemporary. Whatever you are after, Moen offers a variety of styles designed to complement today's decors.

What causes a Moen faucet or valve to leak or drip?

Without a specific model number, it is hard to determine the exact cause of a leak. In general, leaks are often caused by a scratched or torn cartridge, O-ring, or grommet. Typically, a cartridge replacement will correct this type of leak.

What is the advantage of a Moen cartridge?

Our cartridge design made history by being named one of the "best 100 inventions of the 21st century". Our one-piece cartridge is a self-contained assembly; with fewer parts, there is less to go wrong. Our cartridges do not have washers or springs that wear easily, and are easy to repair or replace. Our competitors' designs are often more complicated due to their many movable and loose components. Having more parts increases the potential for more problems, which leads to more repairs. Below are some of the reasons why we are still the standard, more than 40 years after our cartridge was first used in a Moen faucet:

  • Simplicity – Our cartridge assembly contains no complicated parts, requiring less maintenance.
  • Design – Our design eliminates washers and springs, the most common causes of leaks and drips.
  • Ease of Installation – Our one piece design makes replacement quick and painless.
  • Limited Lifetime Limited Warranty – Our faucets are made to last. If something should go wrong, replacement parts will be sent free of charge (see our warranty for details).
  • Material – All of our cartridges are made from high-tech material for optimal performance and long life.
  • Ease of Use – Our handle operation is smooth with the cartridge's greased piston.

Do all Moen products consist of one standard of quality regardless of whether the distributor is a retail or wholesale supplier?

Moen's production line does not differentiate between wholesale and retail models. There is only one grade of brass, only one grade of cartridge and only one grade of warranty coverage–the best. While the numbering system for Moen's wholesale distributors and retail distributors may vary and subtle installation and trim differences may exist. These may include, but are not limited to, packaging, threaded or slip-fit style tub spouts and metallic or non-metallic drain assemblies. The quality and limited lifetime warranty against leaks, drips, materials, and workmanship remain the same for all of our products.

Is there an adjustment that I can make to my faucet to increase the flow of the water?

In 1992, the federal government passed the Energy Policy Act. This law placed strict regulations on flow rates. All manufacturers must adhere to these standards and no adjustments can be made. In some cases, you may be receiving less than the maximum allowable water flow rate. Normally, this is due to low water pressure, a blockage in the plumbing or in the faucet, or a faucet malfunction.

WaterSense is a program sponsored by the Environmental Protection Agency (EPA) to promote water efficiency (it is similar in nature to the EPA's Energy Star program). A product with the WaterSense label indicates that it meets water efficiency and performance criteria outlined by the EPA to help you reduce water use in your home.

Our showerheads include a pressure compensating flow regulator that actively delivers the best water flow for the amount of water that is available. Removal of this will actually diminish performance.

How can I purchase repair parts?

There are three ways you can purchase repair parts. One way is through a local Moen dealer. Second, is through our online store. Third, is by calling our Consumer Services Center at 01 800 718 4345 Customer Service Monday through Friday 8:00 AM to 6:00 PM.

How long does it take to ship parts if I purchase direct from Moen?

Stocked items will arrive within 7-10 business days. If you need your part to arrive sooner, we do offer expedited shipping.

I don't see my faucet on your website, does that mean it's no longer serviceable?

We carry many parts for discontinued models; however, there are exceptions. To determine if we have the part you need, we will ask you to provide the age of your faucet and the model number.

If I contact Moen directly for warranty parts, what type of questions can I expect to be asked?

You can expect to be asked the following questions: What is your faucet's model number? Where did you find the model number? Can you provide proof of purchase? What is the age of your faucet? What is the problem you are experiencing and has any work been done to correct it?

Please be near your faucet when you contact us as we may need to ask further questions or recommend a resolution.

How can I find my model number?

Exact model numbers can be found on your box or on your instruction sheet. If unavailable, you may find the general family series number on the back of the spout (non pullout). The series number will not be the exact model number, but it will be helpful when used in conjunction with the faucet image shown in our Replacement Part Locator. Some of our newer model faucets may have a model identifying tag attached to the supply lines.

I have a Moen 1 handle kitchen faucet and need to replace the O-rings. What are the steps to do this?

Changing the O-rings for most Moen 1 handle kitchen faucets can be done without doing anything below the sink except turning off the water at the supply line valves.

Remove the faucet handle. Most models have a screw behind a red/blue plug button or under the handle cap . After the plug button or handle cap has been removed, use a 7/64" hex wrench to remove the handle screw. Follow the parts breakdown for the order of the handle mechanism. Once the handle mechanism kit is removed (including the spout retainer nut) rotate the spout back and forth while pulling up.

Some Moen faucets have handles that remove by loosening the screw in the back of the handle. To loosen this screw use a 3/32" hex wrench. After the handle has been removed unscrew the spout collar nut by turning counterclockwise then lift and rotate the spout.

Remove the existing O-rings from the valve body noting the location of each. Clean (with 50/50 solution of vinegar and water) the inside of the spout and the outside of the valve body. Lubricate the O-rings using the silicon grease included and install the new O-rings on the valve body. Apply the lubricant to the outside of the valve body and the inside of the spout hub.

A helpful hint:

Always lubricate faucet O-rings with silicone-based grease (Moen part number 99915). Do not use plumber's grade faucet grease, silicon sprays or any lubricant that contain petroleum. Petroleum based lubricants may react with rubber seals and actually cause the faucet to become even more difficult to operate.

Re-install the spout, handle mechanism kit and the handle in the reverse order.

Is the same procedure followed for the 2 handle kitchen faucet?

Changing the O-rings on a 2 handle kitchen faucet is usually easier than a 1 handle. It is not necessary to turn the water off under the sink provided that no one turns the faucet handles to the on position while servicing.

Identifying the specific model number of your faucet and viewing the parts breakdown is suggested .

If the spout rotates and extends towards the sink at a low angle, a cap on the top of the spout unscrews (counterclockwise). A rubber jar gripper or a strap wrench makes this part of the job easier. Once the cap has been removed, rotate the spout while pulling upward.

If your faucet has a spout that is a high fill, cathedral or high arc spout there will be a collar that unscrews counterclockwise. When the collar has been loosened, pull up on the spout and remove it from the faucet. Many spouts will also feature a split white nylon washer to help secure the spout to the faucet.

Follow the same procedure for cleaning, replacing and lubricating as detailed above.

MotionSense™ Operation

How does MotionSense™ operation differ from a standard mechanical faucet?

MotionSense gives you three unique ways to operate the faucet. In addition to featuring a familiar mechanical handle, you can activate the faucet in hands-free mode by waving your hand over the faucet at the Wave Sensor or by placing your hands or an object under the spout at the Ready Sensor.

How do I turn the faucet on/off?

There are three unique ways to turn the faucet on and off:

  • Place your hands or an object under the spout, and the Ready Sensor will sense you in the activation zone. The water will turn off when you exit the activation zone.
  • Motion your hand over the Wave Sensor on the top of the faucet. The water will continue to run until you wave again to turn it off. There is also an auto-safety feature shutoff.
  • The familiar mechanical handle works just like any other Moen® faucet.

Is it safe to have electronics under my kitchen sink?

Yes, similar to your disposal and dishwasher lines, electronics are safe for under the sink area.

How do I turn the faucet off with the sensors? With the handle?

The Ready Sensor will turn off when you exit the activation zone. The Wave Sensor will turn off when you wave your hand over the spout. If you move the mechanical handle on the product, then you need to turn the water off by using the handle. The mechanical handle will always override the electronics mode.

How do I change the water temperature?

Simply use the handle like you normally would. Pull the handle out from the faucet; tilt forward for cold water, backward for hot water. For hands-free mode, change the preset mix on the control box under the sink.

How do I adjust the flow?

You can control the flow or amount of water with the mechanical handle. You cannot adjust flow in hands-free mode. Your faucet will come with a maximum flow rate of 1.5 gpm. This maximum is not adjustable.

How do I increase my water pressure?

Water pressure is driven by your home's water supply. If you are experiencing low flow, Moen recommends that you check your screen filters in the spray head and pulldown hose.

Simply unscrew the spray head and rinse the filter screen as shown:

The filter screen within the hose can also be cleaned as shown:

What is the standard temperature? How do I change it?

To change the temperature, simply use the handle like you normally would. Pull the handle out from the faucet; tilt forward for cold water, backward for hot water.

When in the hands-free mode, the water temperature will be factory preset at slightly above mid-mix (lukewarm).

You can change the hands-free water temperature on the control box. To do this, adjust the round dial clockwise for colder temperature and counterclockwise for hotter temperature.

What are the two lenses on the spout? What do they do?

The two lenses allow the electronic sensors to see what is in the zone. The sensors are a durable polycarbonate material.

How does the faucet know to activate in electronics mode?

The faucet is based on Infrared technology that senses objects within the activation zone.

What does the blue light indicate?

The blue light indicates that you are in electronics mode. The blue light will come on for two seconds whenever electronics mode is activated.

The blue light will flash rapidly to indicate battery life is low (applies to battery-powered option only, not AC service kit).

How do I disable the sensors?

Simply hold your hand above the Wave Sensor for five seconds. The water will stop running and your sensors will be disabled. To re-enable the sensors, go through the same process, holding your hand above the Wave Sensor.

How long will the water stay on in electronic/hands-free mode?

The Wave Sensor features a two-minute safety shutoff feature to ensure water will not run continuously if accidently left unattended. This auto shut-off is a safety feature that assures you won't need to worry about the water running when the faucet is not in use.

When using the Ready Sensor, the faucet shuts off when your hands or an object leaves the sensing zone.

Why does my faucet turn on unintentionally?

If you or an object enters the activation zone, it will turn the water on. Sometimes this can happen when you are reaching for an item behind your sink.

Does the faucet have Reflex®? Will Reflex still work?

Yes, the faucet still has Reflex. The hose bracket was designed as part of the system to ensure that Reflex will still work properly, no matter where the control box is placed under the cabinet.

What is the spout range of motion?

The spout can rotate 100 degrees.

How durable are the electronics?

The electronics are very dependable. The circuit board is completely potted* for protection from water and moisture. The electronics box can be easily replaced by removing one screw and disengaging two connectors. All connectors are UL®-listed and ROHS (Restriction of Hazardous Substances Directive)-compliant. * In electronics, potting is a process of filling a complete electronic assembly with a solid or gelatinous compound for resistance to shock and vibration, and for exclusion of moisture and corrosive agents.

What finishes are available?

The faucet is available in Chrome, Spot Resist™ Stainless and Oil Rubbed Bronze.

Can the faucet be mounted with left- or right-handle installation?

Due to the hose and cable management, the handle must be mounted on the right side.

MotionSense™ Installation and Power Information

How does the installation differ from a standard mechanical faucet?

There are a few additional steps. You will need to mount the control box and battery pack under the sink. You won't need any additional tools outside of those required for a standard faucet installation. The project will only take slightly longer than a standard kitchen faucet installation. A crescent wrench, a Phillips head screwdriver and Moen mounting sleeve tool (SKU # 118305, included) are needed. There are also four extra hose connections, but they are simple push-fit connections.

How is MotionSense powered? Does it need to be plugged in?

Six AA batteries power the faucet. Under normal operation, they should last approximately one year. To replace them, simply open the battery pack door and remove them -- just like replacing batteries in a TV remote.

There is also an AC service kit (SKU # 163712) option available. A special outlet isn't required -- only a common GFCI (Ground Fault Circuit Interrupter) outlet.

Will the valve fit under my standard sink cabinet?

Yes. The control box that houses the valve is only 6" w X 4" h X 2.5" d.

Is this compatible with the Moen Hose Corral (SKU # 159060)?

Yes, MotionSense is compatible with this system. The Hose Corral will improve pullout and pulldown performance in situations where there are under-the-sink obstructions.

Is soldering required?

No soldering is required. The supply hoses are braided with standard 3/8" compression fitting ends. The hoses that plug into the control box are push-fit connections that don't require any tools.

How long does it take to install this faucet?

We estimate one hour, but the timing will vary based on your level of previous installation experience.

What is the purpose of the hose bracket and how do I install it?

The bracket allows the pulldown hose to operate properly by keep it away from the other hoses and under the sink obstructions. To install it, place the end of the pulldown hose into the bracket, as shown below:

If needed, how do I remove the hoses once I have pushed them into the control box?

Simply push down on the gray collar that the hose has been pushed into. While pushing down on the collar, pull the hose in the opposite direction.

How do I uninstall the pullout hose quick-connect, if needed?

Press the two white flaps together that are sticking out of the back side of the black housing. While pressing them together, push towards the hose, and the white piece should pop back to its original position.

How do I uninstall the hoses?

Only hoses numbered 1 through 4 can be removed from the control box. The two hoses coming from the base of the control box are permanently attached.

MotionSense™ Care/Maintenance

How do I clean the faucet?

Use mild soap and water, and dry with a soft cloth. Avoid any abrasive cleaner or abrasive sponges.

How do I clean the lenses?

Use mild soap and water, rinse thoroughly and dry with a soft cloth. Avoid any abrasive cleaner or abrasive sponges.

How do I clean the screen filter in the control box?

Turn off the water supply lines and remove the filter cap from the bottom of the control box using a flat-bladed screwdriver. Rinse debris from the screen, then reinstall. Your flow will improve if debris was previously restricting the flow.

How do I know my batteries are dead?

A flashing blue light will appear in the Ready Sensor lens located at near the base of the spout.

What is the warranty?

Limited Lifetime Warranty against leaks, drips, finish defects to the original consumer purchaser.
5-Year warranty against electronic operation defects to the original consumer purchaser.
5-Year warranty against leaks, drips, finish defects if used in commercial installations.
1-Year warranty against electronic operation defects if used in commercial installations.

MotionSense™ Serviceability

How do I know if I need to troubleshoot the electronics?

Should you ever encounter an issue with your MotionSense electronics, the LED indicator on the control box will blink to alert you. The label on the control box demonstrates the three patterns in which the light will stay on or flash:

How do I replace the electronics box?

The electronics box can be removed in two steps. First, unscrew the screw on the bottom of the box. The box can now be separated from the control box. There are two connectors inside the electronics box that need to be disconnected. Pull the two connectors towards the screw. Once these are disconnected, the electronics box can be shipped back for a replacement.

The grey shaded area represents the electronics box:

How do I replace the control box?

Turn off the water supply at a shutoff point. Disconnect the four hoses by pressing down on the collar around the end of each hose. While pressing down on the collar, pull up on the hose, and it will come out. This should be done on the three hoses entering the top of the control box and the middle hose on the bottom of the box. The two supply hoses on the bottom do not detach from the control box. These hoses need to be detached from their connection at the hot and cold water supplies. Unplug the data and power cables. Unscrew the three mounting screws, and the box should come off the wall. It can now be sent back for a replacement.

How do I replace the spout tube?

Under the sink, remove the data cable from the control box. It is the wire to the right of the power cable. Above the sink, remove the plug button on the back of the spout. Now, push a small diameter screwdriver through the hole where the plug button was. While pressing, pull up on the spout. It should detach from the base. Be careful with the data cable. It needs to pass through a slot in the faucet base and may get caught if care is not taken. Once this is done, the spout assembly can be shipped back for a replacement.

How to replace the hose bracket?

First, remove the hose from bracket. Then, disconnect that hose at the quick connect by squeezing the white tabs together and pushing them in. Pull the hose out of the quick connect. Next, unthread the plastic hose protector at the end of the mounting shank. This piece will slide down the hose and come off. The hose bracket will slide down the hose as well.
