Our PET series expansion tanks eliminate the problem of nuisance cycling of the safety relief valve when a back-flow preventer or check valve is present in a domestic hot water system. Utilizing our all butyl diaphragm system, the PET series tanks provide a reservoir for expanded water volume and help to prevent dangerous over-pressurization. The diaphragm is permanently separated from the tanks air charge. PET tanks also feature a stainless steel system connection for maximum corrosion resistance.
