Does my water heater need a pressure relief valve?

What does the relief valve do? The relief valve is an important safety feature on the water heater. If the water inside the unit gets too hot (usually above 210 degrees) or pressure builds up too high (above 150 psi), the water heater can become damaged or even explore. A good solution to this risk is the relief valve.

How does a pressure relief valve on a water heater work?

Some degree of excess pressure escapes through the water pipes connected to the water heater. In the event that it cannot, the pressure-relief valve triggers. By releasing some of the hot water and air, the valve lowers the pressure back down to safe levels.

Where is water heater relief valve?

Also known as the temperature/pressure relief valve, or the TPR valve, this valve is located near the top of the water heater. It usually features a lever you can lift up or down and has a discharge pipe that runs from the valve down to the water heater’s base.

Why is my hot water heater leaking from the pressure relief valve?

Your water heater’s relief valve can start leaking for one of two reasons: either the valve was triggered to open because of excessive temperature or pressure, or the valve itself is faulty. If the problem is a faulty valve, then you might have an actual leak.
