If a TPR valve leaks, either it’s defective or it’s not. If it’s not defective, it’s leaking because the temperature was too high or the pressure was too high. In other words, a leaking TPR valve indicates one of these things: a defective valve, excessive pressure, or excessive temperature.

What is TPR valve on hot water heater?

Temperature/pressure-relief or TPR valves are safety devices installed on water heating appliances, such as boilers and domestic water supply heaters. TPRs are designed to automatically release water in the event that pressure or temperature in the water tank exceeds safe levels.

How long does a dip tube last?

The dip tubes in most newer water heaters should last the lifespan of the unit (8–12 years). However, some dip tubes also function as a “sacrificial anode rod”, which means it’s designed to attract all the corrosive elements in the water, ultimately protecting the tank from corrosion.

How do you test a pressure relief valve?

Here’s how to test and replace a pressure relief valve. There is a simple test to determine whether the TPR valve is operating correctly. First, place your hand on the overflow pipe leading away from the valve to determine whether the line is hot. There should be some warmth next to the valve, but the line should only be hot if the valve is faulty.
