The relief valve is an important safety feature on the water heater.

Water heater pressure relief valve leaking after testing.

This just happened to us and it turned out the main pressure regulator to the house had failed and was letting the water in at full pressure causing the tpr valve to leak. The temperature and pressure relief valve tpr valve opens to release pressure buildup in the water heater when the temperature or the pressure get dangerously high preventing a possible explosion. Just replace the valve. Water heating is a warmth exchange process that uses a vitality source to warm water over its underlying temperature.

Replacing the old valve with a new one. These valves may look identical but they re set to go off at 30 psi. 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.
