What Are the Parts of a Pull-Out Faucet?

The major components of a pull-out kitchen faucet are the handle, the cartridge, the faucet body, the spray head and the pull-out hose. Other smaller parts that make up the assembly are the aerator, the deck plate, mounting hardware, O-rings and washers.

Manufacturers offering pull-out spray faucets include Price Pfister, Delta, Kohler, American Standard and Moen. Home improvement and plumbing supply stores typically sell these fixtures as a complete assembly, but homeowners can fix minor problems and save money by replacing certain parts rather than the entire faucet. Leaks, for example, typically occur at the connections on either end of the chrome pullout hose, and a clogged aerator may cause pressure loss.
