Replacing a Seat Washer

Tools and Materials Needed:

  • Adjustable wrench
  • Repair kit
  • Utility Knife
  • Screwdriver
  • Handle puller

Plumbing Tip: If you can’t break the faucet handle loose from the stem by prying with a screwdriver, use a handle puller.  They are pretty affordable.

1. Shut off the water supply at the shut-off valve and then pry the index cap from the handle with a sharp tool. (ex: utility knife)

2. Use a screwdriver or Phillips to remove the handle screw from the handle.

3. Drive the stem of the puller into the screw hole.

4. Use an adjustable wrench and loosen the bonnet nut.

5. Lift the stem to expose the seat washer and screw.

6. Reattach the handle to make working on the stem easier, and remove the washer screw.

7. Choose the correct size and shape replacement washer for your faucet by examining the valve seat, and press it into the stem’s retainer.

8. Tighten the washer screw in place and coat the washer ad stem threads with heat-proof faucet grease before reinstalling the stem.

  1. water damage says:

    We recently had a slab leak in our home and have a lot of water damage downstairs and think we may have mold. I’m not sure if testing is a good idea or if we can assume we have it based upon the fact it was a pretty big flood? All our baseboards and drywall got wet about 4 feet up from the floor … total nightmare!

    I appreciate your helpful information.
