In the first case, the valve will drain water out of the discharge pipe as explained above.

Also, how do I stop my hot water from leaking overflow?

When a temperature and pressure (T&P) relief valve at a water heater leaks, it’s usually a simple fix; just replace the valve. These valves cost less than $15, and replacing the valve is a very basic job – just drain some water out of the water heater, remove the discharge tube, and replace the valve.

What causes T&P valve leaks?

Temperature & Pressure Relief Valve Leaks. A leak from the temperature & pressure relief valve (T&P valve) may be caused by overheating or excessive pressure inside the tank. When the T&P valve is under pressure, the valve will open to allow water to escape, and thus, relieve the pressure.

How long do pressure relief valves last?
