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.
How do I release the pressure on my water heater?
