If you notice that water is constantly leaking from your shower, it might be time to change the shower washer. The washer in your shower faucet can get worn or damaged due to normal wear and tear, so you should replace it as soon as possible. Instead of calling a plumber, you can do the job yourself and save some money. With the right set of tools and this guide, you will be able to change the washer on your shower faucet.

Step 1 - Shut off the Water Supply

Shut off the water supply to the shower faucet. If you don't have an individual shut off valve for the shower faucet, you will have to shut off the main supply to your home.

Step 2 - Drain the Water

Open the faucet to drain out any remaining water that may be still in the shower.

Step 3 - Remove the Handle

Remove the handle from the stem of the faucet.

Step 4 - Remove the Nut

You can use a bit of penetrating oil to loosen the nut, and then use the pliers to completely remove the nut from the escutcheon.

Step 5 - Remove the Screws and Washer

Use the screwdriver and remove the screws on the faucet stem. Once the screws are out, you will be able to remove the shower washer. Remove the washer and keep it aside.

Step 6 - Buy a New Shower Washer

Buy a new washer for your shower. You can take the washer to the local hardware store and get a replacement. Make sure the new washer is the same size as the one you just removed from the shower faucet.

Step 7 - Replace the Washer

Replace the washer by putting the new washer in its place.

Step 8 - Replace the Screws

Replace the screws on the faucet stem one by one. Use the screwdriver to tighten the screws.

Step 9 - Use Plumber's Putty

Use the plumber's putty at the bottom of the escutcheon. You only need to use a small amount.

Step 10 - Reconnect the Faucet Stem

Reconnect the faucet stem and handle and reinstall the faucet.

Step 11 - Open the Water Valve

Now you can open the water valve for the faucet or the main supply valve, whichever you turned off. Open the shower faucet and check the shower; it should be working fine now.

That's all you need to do to change the shower washer. The job is not too difficult, and you can do it yourself. It's not a job that will take up much of your time, and you'll save some money, too.
