How to Repair a Single Handle Leaky Shower Faucet
- 1). Turn off the water supply to the shower by shutting off the mains.
- 2). Remove the cover from the faucet handle by prying it up with a pocket knife. Look for a hex screw at the base of the handle if it does not have a cover and remove the hex screw using a hex screwdriver to remove the handle.
- 3). Remove the screw from the handle using a Phillip's-head screwdriver and pull the handle off the cartridge behind it.
- 4). Pull up the retaining clip at the top of the cartridge by sliding a flathead screwdriver underneath it and pulling the clip out. Remove the washer from the end of the stem by pulling it off.
- 5). Place the cartridge removal device that is packaged with your replacement cartridge over the cartridge and turn it using a wrench until the cartridge is removed.
- 6). Align the new cartridge inside the valve and push it in until it is flush. Attach the handle, turn on the water and test the shower.
