Ok, I have read the forums and have located the bypass valve for the water heater. I have turned this and then drained the tank by pulling out the anode rod.
Now comes the silly part I just cannot wrap my head around. The bypass stops the water from entering the 'cold' inlet at the bottom of the tank and forces it up to a tee with the top of the tank where the 'hot' usually exits. But what will stop any water from entering the opening at the top of the tank? (at the hot port)
Does the hot port have a check valve built in or something?
