Patent

CA 2488953

A freezeless wall hydrant has a fluid inlet end connected to a source of pressurized water, and a fluid outlet end. A check valve is placed in the bore of the valve body and is spring loaded to open only when extreme water pressure within the inlet valve lifts a spring loaded piston element to permit the highly pressurized water to move through the bore in the valve body and be relieved as it escapes rearwardly into the original source of pressurized water.
