ABSTRACT:
A faucet includes a body having a main bore including an inlet and an outlet. A bonnet and spout are connected to the body. A stem includes a first portion inserted into the outlet of the main bore and a second portion that projects through the bonnet chamber to a distal end. The first portion of the stem comprises a flow path and the stem is slidably movable relative to the body and bonnet between a first position and a second position. A seal is carried by the stem and is engaged with the stem and sealing face when the stem is located in the first position. The seal is spaced from the sealing face when the said stem is moved to the second position. A handle is operably connected to the distal end of the second portion of the stem. A spring biases the stem to the first position.
