Why does my hot water heater overflow keep discharging water?
Causes of Excess Pressure in a Water Heater Since water expands as it's heated, higher-temperature water occupies more volume, which, in the confines of a water heater, results in increased pressure. If the pressure increases too much, your relief valve will activate, releasing water through the drain pipe.
What happens if I open the pressure relief valve on my water heater?
To open the valve, you simply flip the lever up. After doing this, hot water will flow into the pipe and out into the discharge spot. Opening the valve on occasion will help ensure that it is working properly. Opening it will also help release any excess pressure that is built up inside the tank.

What is a trap in a water heater?
A plumbing “trap" is a part of a pipe where water remains in place after gravity has drained the rest of the water. Because this stagnant water could sit for months and possibly drain backwards into the tank if the TPR valve is opened manually and there is no water pressure at the time, introducing bacteria into the tank, the pipe must completely drain by gravity. A trapped TPR dischage pipe is a common defect when a replacement water heater’s TPR valve is lower than the original one, and the installer connects to the exisitng discharge piping at the wall.
