T&P and ASME Safety Relief Valves - Watts
media.wattswater.comThermal expansion problems can be solved by using a thermal expansion relief device on the system. Devices include auxiliary type relief valves which can be placed anywhere on the system and set approximately to 10psi below the water heater relief valve setting. They allow the auxiliary relief valve to take the brunt of thermal expansion ...

WATER HEATER THERMAL EXPANSION TANKS
www.hotwater.comEXPANSION TANKS FOR HOT WATER HEATERS Many local codes require back flow preventers. Since this seals off the system an expansion tank is required or the relief valve will discharge on every heating cycle. Thermal expansion tanks eliminate this wasteful, costly and dangerous practice. The thermal expansion tank
