Single-handle Disk (ceramic Disk) Faucet Repair and Installation

Single-Handle Disk (Ceramic Disk) Faucets

A single-handle disk faucet is made with a pair of ceramic or plastic disks encased in a cylinder. The upper disk rotates when you turn the handle. Water flows when the inlets of the upper and lower disks line up.

Getting the parts
If water wells up around the handle or drips out of the spout, replace the seals with exact duplicates. If that does not solve the problem, replace the entire cylinder -- you cannot open it to replace disks. If water flow is slow or erratic, particles of rust and minerals may be clogging the inlets. Cleaning them solves the problem.

Prestart Checklist

Less than an hour for most repairs

Screwdriver, hex wrench, cleaning brush

Shutting off water, dismantling a faucet, installing small parts

Shut off the water, close the sink stopper, and place a rag in the sink to catch any parts

Repair kit with seals and O-rings, silicone grease

Step One

Shut off the water. Turn the faucet on until the water stops running. To remove the handle you'll probably need to unscrew a setscrew using a hex wrench or small screwdriver. Lift off the handle and remove the dome housing.

Step Two

Pull out the cylinder that contains the disks and take it to a home center or hardware store to find replacement parts. The O-rings can be pried out of the cylinder using your fingers.

Step Three

On some models removing the bottom plate reveals the rubber seals. Remove them with a small screwdriver, taking care not to nick the plastic housing. If the cylinder is cracked or scored, replace it. Otherwise buy a kit with the rubber seals and O-rings.

Step Four

Before replacing the rubber parts, gently clean away scum and debris from the seats using a toothbrush or a nonmetallic abrasive pad. Rub a little silicone grease on the rubber parts.

Step Five

Reassemble the cylinder. Install the cylinder so it faces the same direction as it did before.
