Tutorial: Installing the Moen 1200 or 1225 Cartridge

Overview

cartridge 1200 or 1225

To complete the project, you should first gather the tools and all the parts you will need. Next, the basic steps are to disassemble the handle, remove the cartridge, reinstall the new cartridge, and test your water.

You should have the following tools available to you before you start: adjustable wrench, channel-lock pliers, open-ended wrench, safety glasses, flashlight, and screwdrivers. You will also need to have a hex wrench (7/64th or 3/32nd, depending on the faucet).

Before You Start…

  • Skill Level & Time to Complete
    • Beginner - About 1 hour
    • Intermediate - About 30 minutes
    • Advanced - About 15 minutes
  • Caution: Before beginning your repair, always turn your water supplies OFF. Then turn your faucet on to be sure the water is completely off and to relieve water pressure.
  • Faucet models have slightly different instructions. Please review each step before installing.
  • If there are no shutoffs under the sink, you would need to shut the water off to the home.


We recommend to always flush the valve before installing the new cartridge:

  • Clean the inside of the valve body with a soft bristled nylon brush (e.g. old toothbrush), to remove any mineral buildup.
  • The next step will send a lot of water through the open valve. Use bowls or similar devices to redirect water from the open valve back to the sink or tub. You may also want to put a towel over the open valve to collect the water.
  • Then, turn on the water supply lines to flush clean water through the open valve. This will push debris up and out of the unit.
