For more than 50 years, Price Pfister has been manufacturing faucets and fixtures in a variety of styles. Their line of kitchen faucets feature such innovations as goose neck spouts, attached sprayers and touch control. Regardless of the faucet features, taking apart a Price Pfister kitchen faucet isn't a difficult operation. The main thing to remember is to turn off the water supply before you start.
Turn off the water supply for the Price Pfister faucet. Look beneath the sink where the faucet is installed to find the two round or oval water supply knobs. Rotate these clockwise to turn off the water. Open the faucet and allow any water inside to run out.
Unscrew the metal couplings from the water supply valve with the adjustable wrench.
Remove the plastic wing nuts on the underside of the sink with the pair of pliers. The sink can now be pulled out of the countertop if needed.
Examine the handle to find the handle screw. This will be of the Allen type and located either on the front or underneath the handle, depending on your Price Pfister model. Remove the screw by unscrewing and pull the handle straight off.
Remove the collar around the top of the faucet. Unscrew the retaining nut in the middle of the faucet with an adjustable wrench. Pull this off to reveal the faucet cartridge.
Pull out the cartridge. On some models, you may need to pull out a small retaining pin in the front with a pair of needle-nose pliers before you can pull the cartridge out. If the cartridge is difficult to remove, use a pair of pliers to grasp it by the top before removing.
