I had the same exact situation occurring. Relief valve was dumping water, and I can’t change the temp setting because it’s factory spec. Replaced it with the exact same relief valve it came with. Still dumping water, so I have a small water bottle to collect it. Dumped it out this morning actually. I need to look at the heater specs and see if I can get away with a higher rated valve as you noted.

Oh gosh, I had forgotten about that. Glad it's holding well :-)

If everything else fails, just put a cup under the discharge hose and empty it periodically.

I called Seaward. Tech support told me their engineers lowered the valve that they now use to 100psi. Tech did not say what the pressure on theold valve was. They are sending me a 150psi valve. My guess is this is what was used in the past. The weeping 100psi valve I also have indicates to me that the pressure must be just above 100psi. I do not have an expansion tank.

Sounds like it's time for an expansion tank. Even a tiny one.

I am not necessarily averse to installing an expansion tank but I do not understand what that gets me.
