The WH 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 patented double 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 WH tanks also feature a brass system connection for maximum corrosion resistance. An appliance quality finish completes the tank so it will look good for years to come.
The WHV Series is designed for larger potable water systems. Like the WH tank, it features a double diaphragm design plus a stainless steel system connection.
