Price Pfister Shower Faucets
There are a couple of common signs that a Price Pfister single-handle shower faucet could use a cartridge repair or replacement. One is a handle that's hard to pull out. Replacing the cartridge will fix this problem, but you can also try simply lubricating the O-rings on the cartridge. Another problem is a water drip when the shower is turned off. In this case, replacing the cartridge is the only solution. These two issues are common with Price Pfister Avante cartridges, and you can find replacement cartridges at most large home centers and through online plumbing parts suppliers.

Turn Off the Water
Shut off the water supply to the faucet by turning off the shower's shutoff valves (if it has them) or by turning off the main water supply shutoff valve to the house. Look for shower shutoffs on the water supply pipes near the shower; they may be concealed behind an access panel on the wall opposite the shower, or they might be under the floor if there is a basement or crawlspace below. Your home's main shutoff valve is on the main water supply pipe coming into the house and is probably located in a basement or crawlspace.Continue to 3 of 6 below.

Remove the Faucet Handle
Remove the decorative cap covering the handle screw on the faucet knob, using a small flat-head screwdriver to pry off the cap. Loosen and remove the handle screw, which usually requires a Phillips screwdriver. Pull the handle straight out away from the wall to remove it.Continue to 4 of 6 below.

Remove the Escutcheon
Unscrew the escutcheon by turning it counterclockwise. It's best to do this by hand, if possible. Otherwise, use tongue-and-groove pliers, and protect the escutcheon from the pliers' jaws with a rag or a scrap of leather.Continue to 5 of 6 below.

Pull Out the Cartridge
Remove the large nut that holds the cartridge in place, turning it counter-clockwise with tongue-and-groove pliers. If the nut is stuck, spray some penetrating oil on the threads, wait about 15 minutes, then try again.
Note the orientation of the cartridge; you must put it (or its replacement) back in the same way.
Remove the cartridge by pulling it straight out of the valve, using the pliers. If the cartridge is hard to pull out, you can try putting the handle screw back onto the end of the cartridge and using it to get a better grip with the pliers.Continue to 6 of 6 below.

Replace or Lubricate the Cartridge
Lubricate the O-rings on the old cartridge with a small amount of waterproof plumber's grease. Reinstall the cartridge, using the same orientation as before. Push the cartridge all the way into the valve, then screw the retaining nut back on, and tighten it with pliers. Alternatively, install a new cartridge using the same techniques.
Turn the water back on and test the faucet before before completing the reassembly. You can simply fit the handle onto the cartridge to turn the water on and off, testing both the hot to cold water flow. If all works well, pull off the handle, then reinstall the escutcheon. Fit the handle back on and secure it with its screw, and add the decorative cap.
Note: If the caulk around the trim plate is loose or cracked, scrape it out with a razor scraper, then caulk all the way around the trim plate with pure silicone caulk to prevent any water from getting behind the plate and into the wall.
