How to Repair Single Handle Kitchen Faucet
Leaky kitchen faucets are bothersome not to mention a waste of water and money.
This repair is for kitchen faucets with a cartridge and only one handle. It’s very easy to do.
To repair a single handle kitchen faucet you only need a few tools and about 30 minutes to one hour of your time.
Tools needed for the job:
- An Allen wrench set
- A pair of channel lock pliers
- Phillip’s screwdriver
- An old towel
- A new cartridge for your faucet
- A small jar’s lid
Shut off both the hot and cold water valves located under your sink.
Release any remaining pressure in your faucet by turning it on after the water has been shut-off.
Cover the kitchen sink’s drain with an old towel to protect the sink from getting scratched up and to keep any small parts from falling down the drain.
Pop-off the decorative cap (hot/cold emblem) on the front of the faucet.
Select the proper size Allen wrench from your set and remove the screw on the front of your faucet. Place the removed screw in the lid of the small jar so that you don’t misplace it.
Take the faucet apart so that you can remove the cartridge. Many times there is a little Phillip’s screw on top that needs to be removed first before you can pull out the cartridge. You may have to hold the housing in place with the pliers while you remove the screw.
Sometimes there isn’t a screw and the old cartridge can simply be removed with a pair of channel lock pliers. There are usually small groves where the pliers can grip on to remove the housing that’s holding the cartridge in place.
Take out the old cartridge but pay close attention to the position in which the cartridge sits within the housing. You will need to insert your new cartridge in the same manner. Take a picture with your smartphone to aid your memory.
Note: A lot of the times you may not need to replace the cartridge. There may be a small piece of debris that’s lodge in the cartridge that’s causing the faucet not to shut-off all the way. Check to make sure there is no obstruction in the cartridge before you buy a new one.
Take the old cartridge with you to your local plumbing supply so that you can get a perfect match.
Place your new cartridge and insert it into the faucet in the same way that your old cartridge was sitting.
Replace any screws, clamps or housing you removed previously.
Reattach the single handle kitchen faucet’s handle and secure firmly with the screw you previously placed in the jar’s lid.
Put back the decorative cap back on the faucet.
Finally, turn the sink’s water supply back on and check to see that there are no leaks.
