DIY steps
- Turn off the water supply to the shower by locating the shut-off valves and turning them clockwise. Open the shower faucet to drain the water from the pipes. Put on your safety goggles and gloves to protect yourself from any potential debris or water spray.
- Disassemble the shower handle by removing the screw that holds it in place. Gently pull the handle off the stem, taking care not to damage the surrounding area. Use an adjustable wrench to loosen any additional retaining rings or clips that hold the cartridge in place.
- Use a cartridge puller to carefully remove the old cartridge from the shower valve. Be prepared for any remaining water to spill out during this process. If the cartridge is stuck, do not force it, as this can damage the surrounding valve body.
- Inspect the valve body for mineral buildup or debris and clean it with a rag, ensuring a smooth surface for the new cartridge. Do not apply plumber's tape to a cartridge; replace or lubricate O-rings only as specified by the cartridge manufacturer.
- Insert the new cartridge into the valve body, ensuring it is properly seated and aligned. Replace the retaining ring or clip that secures it; use a cartridge puller only to remove a cartridge, not to secure one.
- Reassemble the shower handle by replacing the screw and any additional retaining rings or clips. Turn the water supply back on and check for leaks by running the shower faucet through several cycles.
- Dispose of any leftover materials and clean up the work area. Check the shower faucet periodically to ensure the new cartridge is functioning properly and there are no leaks.
