How to Fix a Leaking Pressure Balance Shower Valve

Remove Handle and Face Plate

• Remove indicator button and loosen handle using an Allen (Hex) wrench.
• Using a Philips head screwdriver, remove screws securing the face plate. Then remove face plate.
• Check to see if your valve is equipped with screwdriver stops. If it is, close both valves by turning them in a clockwise direction using a flathead direction.

Remove the dome cap and sleeve

Remove dome cap by hand. Then using channel locks or an adjustable wrench, remove the retaining sleeve.

Inspect and clean spool

Now that you have the spool out shake it side to side. You should hear a rattle.

If you don’t hear it rattle, you can either soak it overnight in a 50/50 solution of water and vinegar to dissolve any mineral deposits that are impeding the plunger from moving freely–or you can always just replace it.

Replace the cartridge

Use the cartridge to properly identify the replacement part.

Assemble everything as it was.

TIPS

• 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 shower head.
• Turn on both valves and let the water run for at least 30 seconds. This will flush debris from the lines.
