What are temperature and pressure relief valves used for?
Temperature and pressure relief valves are used in residential and commercial water heater and hot water storage tank applications to provide automatic temperature and pressure protection to hot water supply tanks and hot water heaters. We have a full-line of products in multiple sizes, pressure ratings, and inlet/outlet types.
Can a water heater explode without a pressure relief valve?
Without the valve, your water heater may run the risk of an explosion if the temperature or pressure got higher than what the tank was designed to handle. To put it simply, storage water heaters can be hazardous or even lethal if they do not come with a temperature and pressure relief valve.
How do you replace Pressure relief valve on hot water heater?
Open the hot water tap and shut off valve on the cold water line. Close the relief valve once the water starts flowing in the steady stream. Turn the hot water tap off once the steady stream of water is established. Make sure the tank is full before running the heater. Turn on the power. Test the valve once again.

There’s a problem with the valve, such as a faulty seal , and the water is unintentionally leaking. Both circumstances should be taken very seriously. If the relief valve is needed frequently, that means there’s an issue with
What would cause a hot water heater pressure valve to leak?
