Why is the T & P valve leaking at the bottom?
When the T&P valve is leaking, it may appear the issue is at the bottom of the tank since the overflow tube discards the expelled water underneath it. Since the T&P valve is designed to allow water to be released from the tank, the first thing to do is check the thermostat setting to make sure that it is not turned up too high.
Why is water coming out of my pressure relief valve?
Is this true? When water is coming out of the pressure relief valve on your water heater, it could signal that too much pressure is building up inside the water heater (which is what the valve is designed for) due to the burner or element not cutting off, in which case the water heater needs to be repaired or replaced.
When do you open the T & P valve?
Most T&P valves are set to open at 150 psi. If the pressure in the tank reaches this level, the valve opens until the excess pressure is released. If pressure caused the release, you’ll usually see about 1 cup of water per 10 gallons in the tank (per release).

Whenever you start the engine, the valve comes alive and waits in a closed position, blocking the flow of exhaust gases.
