Hot Water Issue

Sorry to upset you, Doug. My Buddy does not need to be educated. He told me the very things you mention. There is debris in the valve causing it to mix too much cold water. Until I get this part cleaned properly, my wife and I are very capable of mixing our own cold water to avoid burns. As an added precaution, i have installed a lower temp thermostat in place of the relay that was there. I had 151.2 water, and now have 133 water by measurement. I am prepared for the lower volume of hot water this mod gives.

By the way, I'm sure, had I mentioned the model number many of you would have told me just what my Buddy told me only based on knowing the maker. At least the problem is now solved to my satisfaction. Thanks again, David
