The Pfirst Series single handle kitchen faucet is Pfister’s builder-grade model and is a ball valve, like Delta’s Foundations line, not a cartridge faucet. The rebuild is the same idea: new seats and springs under the ball, and a new cam on top if it leaks around the cap. The two handle Pfirst G136-400 is a different design with 974-098 shear valves.
Before you start. Shut off the two small valves under the sink by turning them clockwise, then open the faucet to confirm the water has stopped. Plug the drain so small parts cannot fall in. You will need a screwdriver, an adjustable wrench or pliers, and for most handles a hex key (an Allen wrench, sold as an inexpensive set at any hardware store). If a shutoff valve will not turn or starts to drip, or anything is corroded and will not loosen with moderate force, stop and see when to call a plumber. New to this? Start here explains the parts and tools in plain language.
