Thanks all. Got the hot water on and all is well. Pulled a panel off and the bypass valves were easy to see, figured out the pipe is an overflow for the tank, the blue knobs make sense now. Is there a separate tank drain? After looking would the front drain be black and grey and rear pipe kitchen drain?
Very possible since black and grey both come from the bathroom and if the kitchen drain is some distance away it will have its own tank. But depends on floor plan. The fresh water tank drain is separate and should be just a white plastic cap near the rear jack
