For a permanent solution consider a small expansion tank.

Expansion is an issue for closed systems. Mine would leak at the water pump fittings if the WH would heat a tank of cold water with no usage. Took a lot of time to eventually find the intermittent issue.
This is what I did. Our B has such a small water system that if I didn't let out some water at the kitchen faucet while water heating the relief valve would leak a bit. My manual (and the notice inside the door of the water heater) says that's normal. I just installed an expansion tank and so far so good.
