Cartridge Overview and Features
The Moen 1222 cartridge is designed for single-handle faucets, allowing users to adjust water temperature and flow with a single motion. The cartridge incorporates technologies aimed at minimizing dripping through quality seals and construction. It is constructed from brass and plastic materials. A key feature of the Moen 1222 is its compatibility with a range of Moen faucet and shower trim kits, offering versatility during fixture updates or renovations. The cartridge facilitates a precise and intuitive user experience.
Preparation for Cartridge Replacement
Prior to beginning the cartridge replacement process, several preparatory steps are necessary. The primary step is to turn off the main water supply to prevent water from flowing during the procedure. After shutting off the water supply, the faucet handle should be opened to release any remaining water pressure within the lines and fully drain them.
The following tools are recommended for the replacement: a Moen Cartridge Removal Tool, a Phillips screwdriver, a hex wrench, adjustable pliers, needle-nose pliers, and safety glasses. While safety glasses are listed as optional, their use is advisable to protect the eyes from potential debris.
Removing the Existing Moen 1222 Cartridge
The removal process involves several steps to disassemble the faucet handle and access the cartridge. First, the handle must be detached by unthreading the set screw. Following this, the handle adapter screw should be loosened, and the adapter itself removed. Next, the Key Stop and Adjustable Temperature Limit Stop are removed, followed by the Stop Tube.
The Cartridge Retaining Clip is then removed using needle-nose pliers. It is important to ensure the cartridge is in the ON position with the notch in the stem facing up when attempting to remove the retaining clip. Once the retaining clip is removed, the Moen cartridge can be extracted from the valve. The Moen Cartridge Removal Tool can also be utilized to assist in the cartridge removal process.
Installing the New Moen 1222 Cartridge
After removing the old cartridge, the installation of the new Moen 1222 cartridge can begin. Before inserting the new cartridge, it is recommended to apply DANCO Waterproof Silicone Faucet Grease to the cartridge oval on both sides. This lubrication aids in smooth operation and helps create a watertight seal.
The new cartridge should be inserted into the valve with the HC symbol and notch in the Cartridge Stem facing up. Once the cartridge is properly positioned, the Retaining Clip should be reinserted to secure the cartridge in place. The cartridge should then be turned to the OFF position, ensuring the notch in the stem faces down.
Following this, the Stop Tube, Adjustable Temperature Limit Stop, and Key Stop are slid onto the cartridge stem. Finally, the Handle Adapter and Handle are reinstalled, completing the installation process.
