Freezeless ground hydrant and method for operating same

摘要

The present invention is for a freezeless ground hydrant having a nozzle above ground and having a main valve adapted to be connected to an underground source of water pressure at a point located below the frost line in the soil. Also underground is a drain water storage system including a storage cylinder. When the hydrant is turned off, the residual water in the nozzle drains into the cylinder and is retained there until the hydrant is turned on again. When the hydrant is turned on, a mechanical linkage connected to the hydrant handle causes the cylinder to expel the drain water therein through a drain line which extends upwardly above the ground.
