Price Pfister single handle shower faucets operate either by rotating the handle or pulling the handle up or out. Despite the different handles, the faucet always functions in the same basic way: water enters the faucet through the hot and cold lines then flows through the cartridge and valve, where the water is mixed and the temperature established. A faulty valve and cartridge can cause a leaky faucet, irregular water temperature, no hot water, or a handle that won't move. You can repair the faucet by replacing the valve and cartridge.

Turn off the main water valve for the house. Turn on the faucet to relieve line pressure and drain the water. Cover the drain with a towel to keep parts from being lost down the drain.
Take off the handle screw under the handle using an Allen wrench, turning counterclockwise. Certain models of Price Pfister faucets have acrylic or metal handles with decorative buttons that conceal the handle screw. Use a small screwdriver to pry off the button. Use a screwdriver to remove the handle screw. Lift off the handle. Remove the limit stop, or dome cap (on certain models).
Remove the hub screw using a screwdriver or Allen wrench (depending on the faucet). Turn the stem extender counterclockwise and remove it. Turn the threaded retaining sleeve, or ring, counterclockwise to remove it. Lift the escutcheon (wall flange) from the wall.
Remove the brass flange that secures the valve using a screwdriver to remove the 4 screws. Pull the valve assembly straight out of the faucet. The cartridge is located directly behind the valve (some valves and cartridges are one piece); pull it straight out. Use a towel to dry up any water discharge as the valve is pulled out to avoid water leaking inside the wall. Use a wire brush or toothbrush to remove any corrosion from the faucet.
Insert the new cartridge and push it all the way into the faucet. Insert the replacement valve or stem assembly. Make sure the mark indicating which direction to turn the valve assembly is in the correct position (check the instructions). Insert the brass flange onto the valve assembly, replace the screws and tighten with a screwdriver to secure the valve assembly. Assemble the rest of the faucet by reversing your steps. Pick up the towel from the drain. Turn on the water and check the faucet for leaks.
Tips and warnings
- Take a picture with a digital camera or your cell phone of each step of the disassembly as a reminder of how the parts fit into the faucet.
- For severe corrosion, it may be necessary to use chemicals to remove it. Wear safety glasses and rubber gloves and ventilate the area. Rinse the chemicals thoroughly from the faucet with water.
