Why is my water heater hissing and leaking water?

If the temperature of the water inside your water heater is too high, it will force your TPR valve to open and release some of the internal pressure, which can cause a hissing sound. You see, the higher the temperature of the water, the more pressure builds inside the water heater tank.

Is a leaking water heater an emergency?

A leaking water heater could be a sign of a major problem. The worst-case scenario could be an explosion if water is leaking due to the pressure being too high. For this reason, if you notice your water heater is leaking, you should call an emergency plumber right away.
