Abstract
A freezeless wall hydrant has a normally horizontal fluid inlet tube with an interior end and exterior end. A hollow valve fitting is rigidly secured to the interior end of the inlet tube for a connection to a source of pressurized fluid. A valve seat is located on an interior end of the valve fitting. An elongated hollow tube of a diameter less than the interior diameter of the inlet tube is positioned on the center line of the inlet tube and has inner and outer ends. A plug is rigidly secured to the inner end of the tube to close the inner end for fluid flow. A normally closed check valve is movably mounted in the tube to engage a valve seat on the plug, to open the tube for fluid therein under conditions of high fluid pressure in the inlet tube.
