How Do I Fix a Dripping Shower Faucet?

The water supply lines are usually located directly behind the shower handles. There should be an access hatch that allows you access to turn off the supply lines. If not, then the supply lines are probably located directly below the shower, in the basement.

Turn Off the Water Supply Lines

The water supply lines are usually located directly behind the shower handles. There should be an access hatch that allows you access to turn off the supply lines. If not, then the supply lines are probably located directly below the shower, in the basement.

Remove the Handles

Pry off the cap that covers the end of the handle with a flat-head screwdriver. Then, unscrew the screw that is inside. With the screw removed, the handle should slide right off of the post.

Remove the Faucet Stem

Use a stem removing tool (available from your local hardware store) to unscrew the stem from the supply line. It will probably be tightly installed, so this may require some force to get it unseated. Examine the stem to see if the threads are corroded or dirty. Clean off the stem as well as possible.

Check the Washer

At the base of the stem is a washer that's held in place by a screw. Check the washer. If it is broken, brittle or it doesn't fit, this will be the cause of the leak. Remove the screw and take the washer out.

Replace the Washer

Take the washer to your local hardware store and purchase a replacement. Install the new washer and secure it in place with the washer screw.

Reinstall the Stem and Handle

Wrap a fresh layer of Teflon tape around the threads on the stem and then screw the stem tightly back into place. Slide the handle back over the stem and secure it in place with the screw. Then, simply snap the cap back in place and turn the water supply lines back on.
