All told me that my tank was not up to code (16yrs old) and I would need an expansion tank in addition to the new tank. One told me I didn't need an expansion tank since I had a thermal expansion VALVE already BUT, that I needed the gas line replaced with a stainless steel, poly coated flex line. None of the others mentioned that. Just for the record, the company saying "no expansion tank but a stainless steel line" was the highest quote.
My question is ... they all seem to know what they are talking about, how can I find out which is truly required? I've tried looking up the code and I am confused. Here is what I found and have been using to do research: "Section 607.3.2 of the Standard Plumbing Code states that if a system with a water heater has a backflow prevention device installed and as a result thermal expansion causes an increase in pressure, a device must be fitted to limit the pressure to 80 pounds per square inch (psi) or less."
