Step 1) As always, turn off the water to the faucet and open the faucet to drain all the water pressure.
Step 2) Remove the handle. Usually there is a cover plate, then underneath is a Phillips style screw that must be removed in order to slide the handle off of the cartridge.
Step 3) Remove the cylindrical sliding cover, and the cartridge retainer clip. This is a small brass clip that holds the cartridge in the faucet body. It can be removed by pulling it straight up out of the groove in the brass body.
Step 4) Pull the cartridge out of the faucet body. To make this step easier, use the cartridge puller!
Step 5) Grease the new cartridge with plumbers grease and insert it straight into the body and re-install the retainer clip and the handle. The 1222 posi-temp cartridge should have an H and a C marked on the cartridge to help in installing it properly. Install the H on the left side.
Step 6) Turn on the water to test the repair. Make sure the hot and cold are coming out properly. If the hot and cold are reversed, then you will want to go back and twist the cartridge 180 degrees in the faucet body to reverse the hot and cold ports of the cartridge.
