There is no indication that your pressure is not right. People were thinking along those pressure lines because you said that the support people told you there was a regulator problem. "Regulator" for a gas water heater is usually to describe a pressure regulator.nly the water heater is hooked up to gas. This is not a propane heater (No offense taken) The warranty is now going to replace the whole new tank. I doubt that it will work. Should I call the power company to check pressure again? Really appreciate the input. I have a few really good plumbers that are stumped .
