How to Fix a Double Handle on a Moen Faucet

Cleveland Van Cecil

Moen makes a two-handled kitchen faucet that uses cartridges to control water flow. Cartridges turn inside the faucet and as a hole in the cartridge aligns with the water supply line, water shoots out of the spout. A series of washers inside the cartridge keep it from leaking.

Double faucet handle leaks may have a washer issue.

When the handle of the faucet starts dripping water, the cartridge is likely the culprit.

  1. Turn the handle on the water supply line underneath the sink to shut off the water to the faucet. Open the faucet to drain any water from the lines.

  2. Remove the cap on the top of the faucet handle using a flat-tip screwdriver. Remove the screw holding the handle on the unit with a Phillips screwdriver. Remove the handle from the unit.

  3. Remove the brass nut from around the handle using a wrench. Turn the brass nut counterclockwise to remove it.

  4. Grab the top of the cartridge with a wrench and wiggle it back and forth.

  5. Insert the new cartridge into the faucet and reassemble.
