Moen Bathroom Faucet Cartridge: A Comprehensive Guide to Understanding and Replacing Your Moen Faucet Cartridge

When your bathroom faucet starts to drip or becomes hard to operate, chances are it’s time to replace the cartridge. If you own a Moen bathroom faucet, you’re in good company—Moen is known for its reliable fixtures and straightforward cartridge replacement process. The faucet cartridge controls water flow and temperature. Over time, mineral deposits and general wear can cause leaks or performance issues, but the good news is you don’t need to replace the whole faucet: just the cartridge typically solves the issue. You’ll need to identify your Moen faucet model to select the correct replacement cartridge—common ones include the Moen 1222, 1225, and 1255 cartridges. Once you have your new cartridge, shut off water to the sink, remove the handle and retaining clip, and swap out the old cartridge. Take pictures during disassembly to make reinstallation a breeze.
