ABSTRACT:
A yard hydrant includes a discharge nozzle above ground level connected to other vertically reciprocal working parts in the ground below the frost line. A cylindrical water reservoir unit, disposed below the frost line around said working parts, includes a diaphragm assembly removably attached to such working parts for reciprocation therewith, and a deformable diaphragm on said assembly provides a water storage area. Residual water in the hydrant when it is turned off is collected in the storage area and returned to the hydrant for discharge through the nozzle when the hydrant is turned on. The working parts are removable from the diaphragm assembly for servicing and repairs.
