If your shower faucet leaks, it will cause problems with your surrounding drywall and wall frames. Mold or rot occurs because of water buildup. Repairing this problem is fairly simple, however. The best part is you will not have to go behind the wall to make the fix. You just need some handyman skills, the right tools and about half an hour.

Things You'll Need

  • Small knife
  • Allen wrench
  • Needle nose pliers
  • New faucet cartridge

Video of the Day

Shut off your main water valve or the valves leading to the shower to stop water flow.

Pry off the cap on the shower handle with a knife, if there is one. Locate the screw on the faucet handle, and loosen it with an Allen wrench. Slide the handle off the stem of the faucet.

Remove the cartridge clip around the tip of the faucet with a pair of needle nose pliers. Pull the washer and cartridge out of the faucet head by hand or with your pliers.

Insert a new faucet cartridge into the faucet head so the notched sections align and it easily slides into place. Put the washer back on. Reinstall the clip by pressing it around the faucet head. Slide the handle of the faucet back onto the stem.

Place the screw into the top of the handle and use the Allen wrench to secure it. Then push the cover cap back on so it snaps into place.
