Abstract
A pull-out faucet has a hollow faucet body with open top and bottom ends and a cylindrical (laterally extending) side opening. A hollow, cane-shaped spout mounts to the top end and seats a spray head at one end. A separate valve block mounts in the housing through the side opening and connects to a mixing valve cartridge lying adjacent thereto on a lateral side. Water supply hoses snap into inlet passages of the valve. One end of a counterweighted spray hose assembly snaps into an outlet passage of the valve block and the other end connects to the spray head. The spray head can be extended from the spout and then retracted. A method of assembling the hoses and valve assembly into the hollow faucet body through the side opening is also disclosed.
