Exclamation Constant water from overflow

My neighbor is having problems with his Richmond model 5V30-6 gas water heater. When the water main to the heater is on, water immediately begins to pour from the drian pipe/pop off valve at the top of the heater.

I am not sure if the valve at the top is the normal overflow or if it is something else.

The water flowing from the valve is warm->hot depending (it was warm when i felt it but the main had been turned off for some time). I have also lifted the lever on the pop off when the water is running out and it does increase the flow.

I don't know if this is a normal if the tank isn't drained, or if there is something else going on.

Any advice would be very helpful. Thanks for your time!!

Thats the valve that is sometimes on top of the water tank and other times its on the side of the water tank tha T/P stands for temp and pressure. Some codes now call for it to be piped to the outside of a home now in copper. Many just hang down on the side of the heater.

Temperature/Pressure relief valve. If the temp or pressure get too high, this valve will open and relieve the pressure inside the tank so it doesn't take off like a rocket should the unitrol never satisfy. Different t/p valves have different relief specs usually printed on the valve itself, so you can match up the temp and psi with the t/p you are replacing.
