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 tank’s air charge. The PH tanks also feature a Stainless Steel system connection for maximum corrosion resistance.
