A leaking Price Pfister bathtub faucet can cause several problems like additional mold growth in your tub near the drain, not to mention the consistent dripping sound in the bathroom.
However, it is a fairly simple problem to fix, if you know how to take apart the Price Pfister bath faucets and get to the cartridge. This cartridge is the only part you need to replace, and it is the one part responsible for controlling the water flow in the faucet.
Shut off the water by closing the home’s main water line near the water heater.
Unscrew the screw underneath the handle along the bottom of the handle with an Allen wrench and remove the handle by pulling it back and away from the faucet.
Unscrew the screws in the trim plate behind the faucet and remove this part. Unscrew the trim sleeve, a cylindrical part on the faucet body, and remove from the faucet.
Unscrew the four screws on the collar around the cartridge in the faucet body with a screwdriver. Take the cartridge out of the faucet body. Replace the cartridge with a new one matched to your model of Price Pfister faucet. Replace the collar and tighten the screws.
Replace the trim sleeve, trim plate and handle and tighten all hardware.
