The T&P (relief) valves are supposed to be tested on a certain frequency. If you've never heard of water heater rocket launching you should look it up. It happens as a result of the T&P getting clogged or stuck shut and then the thermostat getting stuck on.
https://youtu.be/rGWmONHipVo If they leak after test it is usually because some calcium deposits got stuck in the valve seat. You can assist it slightly by pushing down on the brass stem that extends from the center of the valve. This is especially likely if you have never flush the deposits out of the tank. As they age, the spring can simply get weak. I cycle mine every spring to vent the system and every fall when I'm flushing and draining. As far as I know it doesn't leak and I've been doing it since it was replaced 7 years ago.
