How the Johnson Cup® Jet-Flo® Waterer Works
The Control Cup fits loosely within the base cup and is provided with a rubber seat which rests on the jet and thereby controls the water level.
The Cover fully encloses the control cup and serves as a Drinking Basin. Water flows freely from within the control cup into the drinking basin through an opening located slightly above the bottom of the drinking basin.
As the water is used from the drinking basin, the control cup rises allowing more water to enter. When the proper level is reached, the weight of the water in the control cup shuts off the supply of water.
The reducer bushing screws into a 1/2" pipe fitting. An Automatic Shut-Off and Check Valve in this bushing provides easy flushing of the water supply line and stops flow of water when the cup is removed for cleaning. This valve also prevents backward flow in the event of water pressure failure.
Note: The Jet-Flo Waterer is designed to work best at 20 to 45 psi water pressure. If pressure is higher, install a pressure regulator, set at 45 psi, in the supply line ahead of the waterers.
