Pressure Regulator needs an Expansion Tank
Here in the Greater Phoenix, AZ desert, a whole-house pressure regulator valve, also known as a pressure reducer (valve) is sometimes employed to reduce high water pressure supplied by the water company to a safer level for use inside the home, typically agreed to be between 40 and 80 PSI. In most areas, an expansion tank or expansion device must be installed whenever a pressure regulator is installed and there is a tank-style water heater. The expansion tank protects the plumbing components (including the pressure regulator itself) from premature failure due to high pressure resulting from a closed system.
