Compression shower valves are the oldest type of shower valves available in today’s market. However, stopping leaks on this type of shower valve might be easier than you think. Our goal is that by the end of this article, you’ll feel confident enough to tackle this project on your own.
Remove the Handle
Shut off the water supply to the shower. Since compression shower valves typically do not have integral screwdriver stops, it might be necessary to shut off the water at the main water valve at the front of your home.
Pry the indicator button loose by carefully inserting a blade underneath the button and using a Philips screwdriver to remove the handle.
By hand, unthread the flange and nipple.
Remove the Stem
Using either an adjustable wrench or channel lock pliers, remove valve stems by unscrewing in a counter-clockwise direction.
Inspect the Stem.
Once you have removed the stem inspect it for signs of damage, especially on the area around the rubber washer at the bottom. If there is no damage to the stem, remove and replace the rubber washer.
Inspect the Seats
Inspect the seat. If the rim shows signs of wear and tear, remove it with the aid of a seat wrench and replace it.
- With a rag, cover the tub or shower drain. This will prevent small parts from falling into your drain.
- Make sure that the water supply is closed.
- After replacing the appropriate parts, remove the showerhead.
- Turn on both valves and let the water run for at least 30 seconds; this will flush debris from the lines.
