The Model H34 is a sanitary, frost proof yard hydrant. When the hydrant is shut off, all water is contained in the hydrant and piping system, instead of draining into the sub-soil. The thermostatically controlled heating element keeps the water in the hydrant from freezing even at temperatures down to 20 deg below zero. An ASSE 1052 approved Model 50HF Backflow Preventer protects the hose connection from backflow contamination in freezing and non-freezing conditions. The H34 is easy to install, since its connection to the piping system only extends one foot below finished grade. All preventative maintenance procedures and repairs can be completed from the top of unit, without removing hydrant from the source piping.
