How to Repair a Cuthbert Faucet

Steve Smith

A Cuthbert faucet, like many other brands, has an internal cartridge that is a valve to control water flow. This cartridge is seated inside the body of the faucet. When it becomes worn out, water seeps through the cartridge and out the spout. Repairing the faucet is as simple as replacing the cartridge with a new one. You can only use Cuthbert cartridges in a Cuthbert faucet, although the steps to replace the cartridge are the same as in many other brands.

Step 01

Shut off the water supply to the faucet. Take out the plastic cover on top of the faucet's metal handle.

Step 11

Remove the screw under this cap with an Allen wrench and pull the handle off. Or attach a handle puller to the handle and turn the center knob on the handle puller to pull the handle off for you.

Step 21

Grip the base of the brass stem, the part under the handle, with a pair of pliers. Turn it counterclockwise to remove it. Take the stem out, which contains the cartridge valve. Unscrew the small screw at the base of the rubber gasket on the bottom with a screwdriver. Pull the gasket off.

Step 31

Unscrew the nut on the top of the stem by turning it counterclockwise. Pull the rubber O ring off the stem. Place a new gasket on the new stem and tighten the stem screw with a screwdriver.

Step 41

Insert the new stem into the nut and turn clockwise to thread it. Install the new stem in the faucet and turn it clockwise to tighten. Replace the remaining parts to rebuild the faucet.
