ABSTRACT:
A ground hydrant includes an elongated hollow water flow pipe positioned from above the ground to below the frost line in the ground, a flow control valve, and a housing which mounts the flow control valve at a position below the frost line in the ground. The flow control valve has a spherical body with an approximately right angle flow bore through it and a hollow extension tube disposed in flow communication with the flow bore and projecting outwardly from the body and coupled in flow communication with the lower end of the flow pipe. The housing mounts the flow control valve extension tube and spherical body for rotation about the longitudinal axis of the flow pipe between opened and closed positions in which flow communication is respectively permitted and prevented from a pressurized supply of water to the flow tube via the flow bore and extension tube. The flow control valve is rotatable between the opened and closed positions by rotating the flow pipe about its longitudinal axis. The flow pipe can be unthreaded from or threaded with the extension tube of the flow control valve when the control valve is at its closed position. The hydrant also has a support pipe disposed around and spaced sufficiently outwardly from the water flow pipe to permit insertion of a heat tape between them.
