    I think the relief valve is working. I tried hooking the pressure gauge differently and it looks like it opens at 6 1/2 lbs instead of the factory spec of 2 to 5, Don’t know if that’s enough of a difference to cause my flooding. Going back to check the float again. I might have to find a softer relief spring if all else fails!
