How to Fix a Shower Faucet

water dripping from faucetA faulty shower faucet can be such a nuisance, with the cringe-y noise, enduring drips that may quickly shoot up your utility bill, and the dry rot or mold that forms around the bathroom wall with the leak. This makes it important to replace the old shower faucet with a new unit.

But first, what are some causes of a damaged or leaky faucet?

Causes of a Leaky Faucet

  • Water pressure

If you observe that the shower faucet drips water when the handle moves a certain way, then you may be dealing with water pressure problems, leading to the leak.

  • Faulty Cartridge

A cartridge-style faucet is found in faucets with two handles, one for cold and one for hot water. The valve on each handle spot controlling the flow of water into the faucet is the cartridge, and damage to the cartridge may cause the faulty faucet.

  • Broken Washers

Washers undergo a lot of friction, which could cause them to wear out, leading to leaking of the shower faucet. It may also be that the washer was not installed properly or is the wrong size.

How to Fix a Shower Faucet

You can learn how to fix a shower faucet yourself or you can hire a plumbing service for faucet repair. There are two kinds of shower faucets:

  • The Single Handle Shower Faucet
  • The Two-handle Shower Faucet

Single Handle Shower Faucet

  1. Turn the shower off and take out the handle
  2. Also, take out the escutcheon plate. This is so that you can get through to the shower valve.
  3. Get a plier and, with it, loosen the locking nut and pull the cartridge from the valve’s center.
  4. Next, push a new rubber seat along with a spring into the valve by putting it on the end of a pencil and pushing it in. Repeat this for all the other seats.
  5. In the existing valve, put in the new cartridge
  6. Then get the O-ring, slip over the cartridge, and, with the pliers, tighten the locknut.
  7. Fix a new escutcheon plate over the valve and screw it until it is tightly held in place.
  8. Put the new handle onto the valve and then turn on the water.
  9. Adjust the water temperature to 120 degrees Fahrenheit and finally, install a temperature limit so that the valve does not scald.

Two-Handle Shower Faucet

  1. Start by extracting the cover cap to reveal the screw
  2. Once you have the screw in sight, take it out, along with the handle.
  3. Next, go to the faucet stem, loosen it and take it out of the valve body.
  4. Then put the new parts one after the other. These include the O-rings, flat washers, faucet washers, and seals. Don’t forget to take out the screw first before putting it in the washer.
  5. Replace the faucet stem; lubricate linear grooves using plumber’s grease.
  6. Replace the handle and test the valve by running the water. Afterward, plug trim to the wall.
