The repair of a kitchen sink that is leaking can instantly remove a major sound annoyance without taking up much time, effort, or financial investment. If you have a double handled, ceramic disc kitchen faucet, the fix is particularly easy.

What is a double handled, ceramic disc kitchen faucet? The handled part is self-explanatory: your sink has two operational handles, one each for hot and cold water supply. The ceramic disc part refers to the type of valve inside each handle that tells that faucet when to let water through that supply line and how much to let through, according to how much you turn the handle. A ceramic disc sink has a round ceramic disc attached to a cylinder.

Don't know what kind of sink you have? Consult the owner's manual, take apart the handle and look inside, or call a plumber for help.

What You Need:

  • Screwdriver
  • Wrench
  • Kitchen sponge
  • General, all-purpose cleaner
  • Replacement parts kit or replacement seals

Step 1: Prep the Area for Repairs

Start by turning off the water supply by locating the shut-off valve on the pipes under your sink. Turn the valve firmly in a clockwise direction until it stops turning. Test that the water is off by turning on the faucets and checking for a trickle. Leave the faucets turned on to relive pressure when you go to turn the water back on later.

Step 2: Remove the Cylinder

Remove the handles from the sink by unscrewing the screw that goes through the top of each handle. Set the screws and handles safely off to the side for safekeeping.

You should now see a tall cylinder sticking out of the faucet hole.  Remove the nut or screw holding the cylinder in place. Pull the cylinder out and turn it over. You should see rubber seals. Gently pry those seals off with a screwdriver.

Examine the cylinder for signs of dirt or mineral buildups. Clean the surface of the cylinder using a clean kitchen sponge and a general, all-purpose cleaner. Slide the replacement seals onto the cartridge and place the cartridge back in the hole. Secure the cartridge with its nut or screw.

Step 3: Reassembly

Replace the top of the handle and reattach the screw. Remove the plug from the sink drain. Turn the water supply back on at the shut-off valve. Make sure you turn the water back on slowly as a sudden burst of water pressure can damage the ceramic discs. Contact a company, such as Hillside Plumbing and Heating for more information.
