Understanding the Function of a Price Pfister Shower Cartridge
A shower cartridge is a valve component that controls the mix of hot and cold water flowing through the showerhead. In Price Pfister faucets, this cartridge plays a vital role in ensuring a balanced water temperature and pressure. When the handle is turned, the cartridge adjusts the water flow from both hot and cold lines, providing the desired mix for your shower.
Over time, wear and mineral buildup can affect the efficiency of the cartridge, leading to leaks, drips, or uneven temperature control. That’s why knowing when and how to replace a Price Pfister shower cartridge is essential for every homeowner.
Common Symptoms of a Faulty Cartridge
- Leaking from the showerhead when the water is turned off
- Difficulty adjusting water temperature
- Inconsistent or fluctuating water pressure
- Stiff or stuck faucet handle
These issues can often be resolved by cleaning or replacing the cartridge with a compatible Price Pfister model.
Types of Price Pfister Shower Cartridges
Price Pfister, now often branded as Pfister, offers a range of cartridge models to suit different faucet types and installations. It’s important to identify your current cartridge to select the correct replacement.
Single-Handle Shower Cartridges
Most modern Price Pfister shower systems use a single-handle cartridge, which controls both water volume and temperature. Models like the 974-291 or 974-042 are common in many homes and compatible with several Price Pfister faucet styles.
Two-Handle Shower Cartridges
Older shower setups may use two separate cartridges for hot and cold water. These are often found in classic or vintage bathroom designs. Replacing these cartridges usually involves identifying the correct left-hand and right-hand model.
Thermostatic Cartridges
Some high-end Pfister systems feature thermostatic cartridges that automatically maintain a pre-set temperature. These cartridges are more complex and may require professional installation, but they offer superior control and comfort.

Before purchasing a replacement, identifying the correct model of your shower cartridge is essential. You can do this by:
- Checking the faucet manual or original installation documentation
- Looking for a part number on the old cartridge
- Measuring the length and design of the cartridge
- Taking the old cartridge to a hardware store for comparison
If you’re unable to determine the model, Pfister customer support can often assist by matching a photo or description with the correct part.

Step-by-Step Guide to Replace a Price Pfister Shower Cartridge
Follow these steps carefully to replace the cartridge safely and correctly:
Step 1: Turn Off Water Supply

Step 4: Clean the Valve Body
Remove any debris, mineral buildup, or old grease inside the valve housing. Use a cloth or mild cleaner as needed.
Step 5: Install the New Cartridge
Apply silicone grease to the O-rings of the new cartridge. Insert it into the valve body, ensuring it’s aligned correctly and pressed in firmly.
Step 6: Reassemble and Test
Reattach the trim plate and handle. Turn the water supply back on and test the shower. Check for leaks and ensure smooth temperature adjustment.
