Got a question for ya. This is Bill Julian. (Plumber) How would I pipe 3 hot water heaters so I don't create a reverse loop and they draw equally together. I have 3 120 gallon heaters. I'm told by the inspector that I am over working one heater the system is not equally drawing. Said something about a reverse loop and the tees have to situated correctly.
All the colds got in series all the hots come out in series I have the hot 3/4 tee to fixtures near the end of the 3rd heater.
