Replacement Shower and Tub/Shower Valves

Q. "How do the shower stall faucet bodies attach to the shower stall?"
A. They are very easy to install. Remove the index buttons and unscrew the handle screws and remove the handles. Next, unthread the chrome plated escutcheon flanges and remove them and the red fiber gasket from the valve. The brass body threaded shanks are 1" diameter and the holes in the metal or fiberglass wall should not be larger than 1-1/8" in diameter. Determine if the piping will be dropping in from the ceiling or rising up from the floor and adjust the placement of the valve accordingly. Push the threaded shanks into the holes in the metal or fiberglass wall from the backside of the shower wall. You may need someone to help you hold the valve in place from the back side as the red fiber gasket and the chrome plated escutcheon flanges are installed from the inside of the shower. With the threaded shanks pushed through into the shower wall, place the two red fiber gaskets on the two shanks, one on each shank. Thread the chrome plated escutcheon flanges onto the threaded shanks hand tight. The red fiber gasket helps the escutcheon flanges to slide smoothly while being tightened, and once tight help to create a water tight seal. Once hand tightened then tighten the escutcheon flanges just a quarter of a turn more with a wrench. Do not over tighten or you can break the escutcheon flanges. Now re-install the handles and the valve is mounted to the wall of the shower.
