Replacement Directions

screw-cover-small1. Turn off the water supply:

Turn off the water supply by turning the water supply valve(s) clockwise until it can no longer be turned.

2. Remove Faucet Handle:

  • To remove the faucet handle, you must first find the cap which covers the screw that holds the handle and faucet together. Once the cap has been located, use the flat head screwdriver to pry the cap off. Set the cap aside in a place in which it will not be lost.
  • Once the screw has been exposed, use the appropriate sized Allen wrench or Phillips head screwdriver to remove the screw.
  • Now that the screw has been removed, pull the handle off of the faucet. Set the screw and handle in a safe place.

3. Remove Parts to Get to Cartridge

  •  All faucets are not made the same. In some cases you may see a retaining nut as soon as the handle has been removed. If this is the case, use an adjustable wrench or pliers to unscrew the retaining nut.
  • If the retaining nut is not the first thing you see once the handle has been removed, you will most likely find a decorative collar. Unscrew the decorative collar and set it aside.
  • Next you will find a bracket which is attached to the faucet cartridge. Using a Philips head screwdriver, remove the screw holding the bracket in place. Once the screw is taken out, remove the bracket and set it aside in a safe spot.
  • Now  you should see a white plastic ring. Remove this ring and set it aside.
  • You should now see a stem washer. Remove the washer and set it aside as well.
  • Finally, you should finally be able to see the retaining nut, if you have not already found it. Remove the retaining nut by screwing it counter-clockwise with an adjustable wrench or a pair of pliers.

4.Remove Cartridge:

  • You will now be able to see the faucet cartridge. The cartridge is kept in place by a U-shaped brass clip. To remove this clip, place your flat head screwdriver behind it and pry it off. Once free, remove the clip and set it aside.
  • Now you can use a pair of pliers or an adjustable wrench to remove the cartridge. Sometimes this can be difficult, as minerals from water may collect and wedge the cartridge in tighter. If this is the case, most cartridge replacement kits come with a plastic square-shaped tool. Place this plastic tool on top of the cartridge and us a pair of pliers or a wrench to loosen the cartridge by twisting it back and forth. In some extreme cases, the cartridge may still remain stuck. If this happens, you will need to use a Cartridge Puller.

5.Replace Cartridge:

  • Apply a coat silicone plumber’s grease to all rubber parts of the new replacement cartridge.kerox
  • Pull the stem of the replacement cartridge to until it is facing in an upward position.
  • Take your replacement cartridge and place it into the cartridge housing, making sure that it is aligned correctly. The cartridge tabs should be correctly aligned in the clip notch. Make sure the cartridge is pushed down all the way.
  • Re-install the retainer clip. You will know the clip is correctly placed when you hear a click noise. The square-shaped plastic tool that came with your cartridge replacement kit may be used to help turn the cartridge until it is properly aligned with the retaining clip.

6. Reassemble Faucet Handle:

Now that the replacement cartridge is in place, reassemble the each part of the faucet handle in reverse order of which you removed it.

7. Turn the Water Supply Back on

8. Test the Faucet

  • Now that your faucet is reassembled, test it by turning on the water. Make sure there are no leaks.
  • If your hot and cold water have been reversed, this means you put the cartridge in backwards. You will need to disassemble the faucet handle again and reverse the cartridge.
