The PH series eliminates the problem of nuisance cycling of the safety relief valve when a backflow preventer or check valve is present in a domestic hot water system. Utilizing Flexcon's all butyl diaphragm system, they provide a reservoir for expanded water volume and help to prevent dangerous over-pressurization. The diaphragm is permanently separated from the tanks air charge. The PH tanks also feature a stainless steel system connection for maximum corrosion resistance.
