Moen 2 Handle Bathroom Faucet Cartridge Replacement

Replacing a Moen 2 handle bathroom faucet cartridge is a relatively simple task that can be completed in under an hour. By following these step-by-step instructions, you can save yourself the expense of calling a plumber.

Materials:

* New Moen 1222 or 1225 cartridge * Allen wrench * Adjustable wrench * Screwdriver * Bucket or bowl * Rags or paper towels

Steps:

Turn Off the Water Supply:

Locate the water supply valves beneath the sink and turn off both the hot and cold water valves by turning them clockwise. Open the faucet handles to release any remaining water pressure. 2.

Remove the Faucet Handles:

Using the Allen wrench, remove the small set screws located on the front of the faucet handles. Once the set screws are removed, pull the handles straight towards you to remove them. 3.

Unscrew the Bonnet Nuts:

Beneath each faucet handle, you will find a bonnet nut. Use the adjustable wrench to loosen and remove the bonnet nuts. Be careful not to damage the finish of the faucet. 4.

Remove the Cartridges:

Once the bonnet nuts are removed, you can pull the cartridges straight out of the faucet body. The cartridges will have two O-rings, one on each end. Inspect the O-rings for any damage and replace them if necessary. 5.

Insert the New Cartridges:

Align the splines on the new cartridges with the splines in the faucet body and push the cartridges into place. Make sure the cartridges are fully seated and the O-rings are properly aligned. 6.

Tighten the Bonnet Nuts:

Hand-tighten the bonnet nuts onto the faucet body. Use the adjustable wrench to further tighten the bonnet nuts, but be careful not to overtighten them. 7.

Reinstall the Faucet Handles:

Place the faucet handles back onto the stems and tighten the set screws with the Allen wrench. 8.

Turn On the Water Supply:

Turn on the water supply valves beneath the sink and check for any leaks. If there are any leaks, tighten the bonnet nuts a little more. 9.

Test the Faucet:

Open the faucet handles and adjust the water temperature and flow to ensure that the new cartridges are working properly and that there are no leaks.

Tips:

* If you are unsure about which replacement cartridge you need, consult the Moen website or a qualified plumber. * If the faucet is old or the cartridges are particularly difficult to remove, you may need to use a penetrating oil to loosen them. * If you encounter any difficulties during the replacement process, do not hesitate to contact a qualified plumber for assistance. Replacing a Moen 2 handle bathroom faucet cartridge is a straightforward and inexpensive repair that can be completed in a matter of minutes. By following these instructions carefully, you can ensure that your faucet is functioning properly and avoid the hassle and expense of calling a plumber.
