How to Fix a Tuscany Shower Faucet

Tuscany shower assemblies utilize a single faucet valve to control the flow of water as well as the water's temperature. This faucet design features a metal or plastic cartridge controlled by a movable stem. Leaks from Tuscany faucets can be traced to a broken or corroded O-ring on the faucet valve itself. Thankfully, fixing the leak by replacing the damaged O-ring is an inexpensive repair which can usually be performed in approximately 15 to 30 minutes without the assistance of a professional.

Step 1

Locate the main water meter, and turn off the supply of water to the home.

Step 2

Remove the single screw in the center of the faucet's handle with a screwdriver. This screw holds the handle in place. Once the screw is removed, pull the handle off the faucet's stem.

Step 3

Remove the screws that hold the escutcheon plate against the shower's wall with a screwdriver, then remove the plate from the wall. The escutcheon plate is used to conceal the shower faucet and to prevent water from entering the interior of the wall.

Step 4

Remove the damaged faucet by first removing the single retaining nut that surrounds the faucet with a deep-socket connected to a socket wrench. Insert the socket into the wall, then turn the socket until it locks onto the retaining nut. Turn the retaining nut counterclockwise with the socket wrench until the nut is loose, then pull the nut out of the wall. Use a pair of pliers to pull the faucet out of the wall.

Step 5

Locate and replace the faucet's single rubber O-ring. The O-ring is located at the back of the faucet and can be removed by sliding the blade of a small flathead screwdriver underneath the O-ring and prying it off the faucet. Apply silicone grease to the replacement O-ring, then slide the new O-ring into place on the faucet.

Step 6

Insert the repaired faucet into the wall and install the retaining nut over the faucet with the socket wrench. Position the escutcheon plate against the wall over the faucet, then install and tighten the plate's retaining screws with the screwdriver.

Step 7

Position the faucet's handle onto the stem of the faucet, then insert the handle's single retaining screw through the center of the handle and tighten the screw with a screwdriver. Turn the water supply back on to complete the repair.
