Gerber shower faucet repair is generally going to be very similar to Gerber bathtub faucet repair. Gerber manufactures single handle, dual handle and triple handle faucet designs.
Regardless of which design you have in your home, repairing Gerber tub faucets is generally the same no matter which design you have in your home.
There are two main reasons why faucets need to be repaired so frequently. The first is that the faucets receive a lot of wear-and-tear because of constant use. Secondly, hard water and mineral deposits combine to wear out the washers and seals within the faucet.
Before you begin any work on your faucet, make sure that the water is turned off to the faucet that you will be working on and open the valve to let any water remaining in the pipes drain out. Remove the screw in the center of the handle so that you can remove the handle. The screw may be concealed by a decorative cover that you will need to remove to access the screw.
Next, remove the escutcheon plate behind the handle by removing the retaining screw(s) and pulling the plate away from the wall. The cartridge should now be completely exposed. Use a pair of adjustable pliers to pull the cartridge out. Try to pull straight out so as to avoid damaging the fixture.
Clean the cartridge and look for signs of wear and damage. Replace any parts that look old, cracked or worn and replace the fixture in the opposite order that you removed it. Turn the water back on at the main valve and test out faucet. If the leak is no longer present, you have repaired the shower faucet. If, however, the leak still persists, call a licensed plumber to determine what the problem is with your tub or shower faucet.
