How to Change a Price Pfister Shower Cartridge: A Step-by-Step Guide

Replacing a worn-out Price Pfister shower cartridge can be a surprisingly straightforward DIY project, saving you the cost of a plumber. This guide provides a clear, step-by-step process, empowering you to restore your shower's functionality with ease. This process applies to many Price Pfister shower valve models, but always refer to your specific model's instructions if available. Before beginning, remember to turn off the water supply to avoid a soaking!

What You'll Need:

• New Price Pfister Shower Cartridge: Ensure you purchase the correct replacement cartridge for your specific model. The model number is usually found on a sticker on the valve body itself. Take a picture of the label to avoid errors.
• Screwdrivers (Phillips and flathead): You'll likely need both types.
• Pliers (needle-nose are helpful): For gripping small parts.
• Penetrating oil (optional): To loosen stubborn screws.
• Towels: To absorb any spilled water.
• Flashlight: To illuminate the area if needed.

Step-by-Step Instructions:

1. Turn Off the Water Supply

This is crucial! Locate the shut-off valves for the hot and cold water lines supplying your shower. Turn both valves clockwise to completely shut off the water. To double-check, turn on your shower faucet to ensure no water is flowing.

2. Remove the Shower Handle(s)

Most Price Pfister shower valves have a decorative handle or handles. These usually require a small screw underneath or on the side, hidden by a small cap. Carefully remove this cap (often using a flathead screwdriver), then remove the screw(s) securing the handle(s). Pull the handle(s) straight off.

3. Access the Cartridge Retaining Nut

Once the handle(s) are removed, you'll see the cartridge retaining nut. This nut secures the cartridge in place. It might be a simple nut or it might be more complex, potentially requiring a specialized tool provided by Price Pfister for some models.

4. Remove the Retaining Nut

Use the appropriate pliers (or screwdriver if required) to carefully turn the retaining nut counter-clockwise. It may be tight; use penetrating oil if needed and allow it to soak in for a few minutes. Be gentle to avoid stripping the nut.

5. Remove the Old Cartridge

With the retaining nut removed, the old cartridge should now be easily pulled out. It may be slightly stubborn, but a gentle tug should be sufficient. Note the orientation of the old cartridge before removing it; this will help you install the new one correctly. Take photos of each step if you're unsure.

6. Inspect the Valve Body

While the cartridge is out, take a moment to inspect the valve body for any signs of damage, mineral build-up, or corrosion. Clean any debris you find.

7. Install the New Cartridge

Carefully insert the new cartridge into the valve body, ensuring it's aligned correctly. Refer to the orientation of the old cartridge if necessary. Push it firmly until it seats properly.

8. Reinstall the Retaining Nut

Tighten the retaining nut by turning it clockwise. Do not overtighten; this can damage the nut or the cartridge.

9. Reinstall the Handle(s)

Reattach the handle(s) to the valve body, making sure they're securely fastened with the screw(s). Replace any decorative caps.

10. Turn the Water Supply Back On

Slowly turn the hot and cold water supply valves counter-clockwise to turn the water back on. Check for any leaks around the valve and handle.

11. Test the Shower

Turn on the shower and check for proper hot and cold water flow. If everything works correctly, congratulations! You've successfully replaced your Price Pfister shower cartridge.

Troubleshooting:

• Cartridge Doesn't Fit: Double-check you've purchased the correct replacement cartridge for your model.
• Water Leaks: Ensure the retaining nut is tightened sufficiently but not overtightened. Recheck all connections.
• No Water Flow: Verify the water supply valves are fully open.

Remember, if you encounter any significant difficulties, it’s always best to consult a professional plumber. This guide is intended as a helpful resource for simple cartridge replacements, but professional assistance may be required for more complex issues.
