Why is water coming out the overflow on my water heater?
Continuous water heater leaking into the water heater overflow pan can be caused by corrosion and sediment build up inside the tank. The temperature/pressure valve on your water heater is a safety feature to release water if the temperature and pressure in the water tank get to be too high.
Why is water coming out of the top of my hot water heater?
Malfunctioning Temperature and Pressure Valve A very common cause of gas hot water heater leaking from the top is a malfunctioning or damaged temperature and pressure valve, also known as a temperature-pressure relief valve. You may have to replace it or check the heat and pressure inside the tank.
What is the valve on top of my water heater?
A temperature pressure relief valve is a valve that’s located somewhere near the top of your water heater. The purpose of the temperature pressure relief valve is to release water, and in turn lower the pressure inside the tank, in the event that the temperature or pressure gets too high in your water heater.
Why is my hot water heater pressure relief valve leaking?
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.
How does a tank overflow work?
As the pressure from the hot coolant builds and exceeds the rating of the radiator cap, it will compress the larger spring to expose the overflow port. This allows any steam and excess coolant to pass through the line and into your overflow tank and remain in there until the temperature in the system drops.

What is a water heater overflow?
The water heater overflow is also called the pressure relief valve. This safety device will vent a water heater if the pressure inside becomes too great. Because of that, the overflow cannot be compromised or replaced with a plug. A working safety valve must always be in place on every water heater.
What causes a hot water heater relief valve to leak?
The two most common reasons for a hot water heater relief valve leaking are excessive temperature or excessive pressure.
What happens if the TPR valve on a water heater fails?
The TPR valve is attached to a discharge pipe that aims the overflow at the floor or ground where your hot water heater is positioned. If the TPR valve were to malfunction, pressure inside the tank could cause the tank to explode, causing terrible damage to your home. You can see what would happen here:
