If your Moen faucet is leaking, a simple repair may correct the problem. Moen uses a cartridge system to control water flow. This is true in all models, including the Camerist. It takes just a few basic skills to replace the cartridge and no special tools are required. It requires about a half hour of time. After the replacement, the faucet will operate like new again.
Things You'll Need
Allen wrench set
Replacement cartridge kit
Turn off the water supply to the faucet.
Take out the cap on the front of the faucet and remove the screw under it with an Allen wrench. Pull off the handle by lifting it straight up and off the base.
Loosen the handle dome and cartridge nut by turning them to the left and lifting them off the faucet. Discard the cartridge nut.
Pull the cartridge out of the faucet. Gently twist it back and forth with pliers if it does not come right out. Remove the O ring and spacer and replace them with new ones from your kit. Insert a new cartridge, also from the replacement kit.
Replace the cartridge nut with the new one supplied in your repair kit, and tighten it down with pliers. Install the handle dome and handle. Tighten the handle screw with an Allen wrench.
