MTM Hydro's Thermal Relief Valves with Barb keep your pump safe by monitoring water temperature and opening if the temperature excedes 135F. As pumps cycle for extended periods of time, the water temperature rises and can damage internal components including the unloader. Thermal Relief Valves should be installed in low pressure lines near the pump inlet to protect the water intake from accepting a high temp supply. Attach a 1/4 hose line to 7mm Barb to run the hot water back into your tank or drain and avoid the puddle that traditional Thermal Releif Valves cause. WARNING This product can expose you to chemicals, including DINP and/or DEHP which is known to the state of California to cause cancer or birth defects or other reproductive harm, go to www.p65Warnings.ca.gov for more information. The products we sell are not intended for use in potable water systems and are only for industrial non-drinking water applications.
