Description & Documents
Thermal / hot water heater expansion tanks prevent hot water from back flowing into a cold water line or from escaping through the pressure relief valve and onto the floor. They prevent constant fluctuations in water pressure that damage the heater and associated piping. National plumbing code mandates installation when a backflow preventer is present. The G12 is to be used with 100 gallon or less hot water heaters. The system connection is 3/4" NPTF and the max working pressure is 150 psi. When precharged from the factory it features 40 psi. Its max operating temp is 200°F. The G12 does include a saddle valve in the box (5 year warranty).
