Deep socket kit
Diverter valve washer
Price Pfister uses a handle-operated diverter valve for its shower assemblies. The valve is located behind the middle handle of the three-handle faucet assembly. Price Pfizer's diverter valve uses a compression stem and a single rubber washer to redirect the flow of water from the tub's spout to the shower head so that the shower can be used. Once this single rubber washer has worn out, leaks will result even when the diverter is closed. Fixing a leaky Price Pfister diverter valve for a shower assembly is not complicated.
Cut off the water supply by turning the supply valve in a clockwise direction. The supply valve is next to the main water meter outside of the house.
Remove the diverter valve's handle. First remove the single screw in the center of the handle with a screwdriver, then pull the handle away from the wall.
Remove the single retainer nut that secures the trim plate against the shower's wall. The trim plate is the chrome piece that rests against the wall of the shower and conceals the diverter valve. To remove the retainer nut, grasp the nut with slip-jaw pliers, then twist the nut in a counterclockwise direction until loose. Pull the trim plate away from the wall to remove it.
Remove the diverter valve from within the shower's wall with a deep socket kit. The deep socket kit is specifically designed to access and remove the diverter valve, as the valve is recessed within the wall. Simply position the tool over the diverter valve, then twist the deep socket kit in a counterclockwise direction to unscrew the valve.
Remove the single screw at the back end of the diverter valve with a flathead screwdriver. This single screw holds a rubber washer against the valve. This washer must be replaced. Once the screw is removed, take the washer to a hardware store to find an exact replacement. Coat both sides of the replacement washer with heat-proof grease, then slide the washer onto the screw. Insert the screw into the back of the diverter valve, then tighten the screw with a flathead screwdriver.
Insert the diverter valve into the assembly within the shower's wall, then tighten the valve by turning it in a clockwise direction with the deep socket kit. Place the trim plate over the diverter valve, then install and tighten the plate's single retainer nut with slip-jaw pliers to secure the plate in place.
Install the diverter valve's handle. First slide the handle onto the diverter valve, then insert and tighten the handle's single screw through the center of the handle. Turn the water supply valve in a counterclockwise direction to restore the structure's water supply and to complete the repair.
