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 relieving, and prevent unnecessary relieving cycles by the T&P relief valve.
