This article will explain how to install a ceramic disc cartridge for a single-handle faucet.

Please note that the images are for reference only. The product shown in this article may differ from yours, but the information below is still relevant.

To install a ceramic disc cartridge, you must:

1. Remove the old cartridge.
2. Install the new cartridge.
3. Test for leaks.

Please Note: Before doing any work on your faucet, ensure you have shut off the water supply for the faucet.

Once the water is turned off, you are ready to begin.

Step 1 - Remove the old cartridge

• After you have removed the handle, remove the trim cap by unscrewing it counter-clockwise. If the trim cap is difficult to remove, wrap a rubber glove around it for a better grip.

• Apply a pair of pliers or an adjustable wrench on the flat slots of the lock nut. Rotate counter-clockwise to remove the lock nut.

• Hold the stem of the cartridge and pull up until the cartridge is completely removed from the faucet body.

STEP 2 - Install the new cartridge

• Locate the locating pins on the bottom of the cartridge and locate the corresponding holes in the faucet body. Insert the cartridge and rotate it until it locks into place.

• Re-install the lock nut with a pair of pliers or an adjustable wrench to grip the flat slots. To avoid over-tightening the lock nut, hand tighten the lock nut clockwise first, then with a pair of pliers or adjustable wrench, rotate a quarter turn further. Overall 10-14 lbs of torque are required to properly install the lock nut.

• Re-install the trim cap by rotating it clockwise.

Step 3 - Test for leaks

• Once all of the parts are re-installed, turn on the faucet water supply and turn the faucet on. If you notice that the water is leaking from the ceramic disc cartridge, rotate the lock nut another quarter turn with a pair of pliers to tighten it further and test once again.
