To address this issue, verify that the handle is turned all the way counter-clockwise to the 9 o’clock position. If the handle stops before reaching this point, then the temperature limit stop will require repositioning. Additionally, if the water pressure drops while transitioning from cold to hot, the 1222 cartridge may need to be replaced.

Moen recommends cleaning and flushing the valve body when installing a new cartridge. Doing so removes any mineral build-up and loose debris that may have accumulated inside the valve body. These particles have the potential to damage the new cartridge or block the flow of water.

If you have a one-handle faucet with a 1222 cartridge, you can lubricate it by removing the cartridge and applying a silicone-based grease (DANCO Waterproof Silicone Faucet Grease) to both its interior and exterior.
