Is it normal for water to come out of pressure relief valve?
While it’s normal for some water to leak from the pressure relief valve, the unit itself should never leak water. This can happen when the valve doesn’t properly relieve pressure from the unit and, in response, the tank ruptures.
What causes a water heater relief valve to discharge water?
If at any point the temperature or pressure reaches an unsafe level, the water heater triggers the relief valve to open and release water out of the tank until the temperature and pressure return to normal.
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.
Why is my water heater hissing and leaking water?
Internal Tank Leak
A faulty drain valve can cause your water heater to hiss. Hissing or sizzling sounds can occur when water from the water heater’s tank hits hot surfaces. Infrequent hissing (e.g., if it only occurs after using large amounts of water) sometimes happens when condensation drips onto a hot surface.

What causes too much pressure in a hot water heater?
In short, when the temperature or pressure of the water heater gets too high, the valve opens, and releases water that’s causing the increase in pressure. The problem is that many homeowners don’t realize they need to be testing their T&P valves every 6 months, and replacing them every 5 years.
Why is hot water coming out of my overflow pipe?
Hot water systems
Water expands when heated, pressure builds up in the tank and is released through the overflow pipe. So water dripping or running from the valve can be a sign of a normal, functioning system. However, not all leaking overflow pipes are occurring due to normal pressure build up.
Why does my pressure relief valve keep opening?
Why Does the T&P Valve Keep Opening? Hopefully, it’s open because it’s doing its job. It’s supposed to open to relieve pressure in the tank when necessary. If this is happening with frequency, you should consider lowering the temperature.
How do I stop my water heater from hissing?
If the water in the tank gets too hot, it will open to release some of the pressure and avoid the tank exploding. This action results in a hissing noise as the pressure is released. In order to fix this problem, you will need to lower the temperature on your water heater.
