WattsRegulatorCo. Relief Valves Editorial Review

The Watts Regulator Temperature and Pressure Relief Valve 40XL-5, 3/4" (0156731) is a durable and reliable valve for regulating temperature and pressure in your home's water heating system. The metal tag on the valve indicates a PSI rating of 150, and a maximum heater input temperature of 210 degrees. The 40XL-5 model is not adjustable and cannot be manually changed from 100 psi to 150 psi. Overall, this valve has received positive feedback from customers. Some buyers have reported confusion about the PSI rating due to different colored tags, but it seems that the valve does come configured for a 150 PSI limit. As long as your heater input temperature is below 210 degrees, this valve should work effectively.
