|In response to Re: thermal expansion tank for water heater|
: A month ago water started flowing from the water heater relief value when the water was heating. I've heard rumors that I need a Thermal Expansion Tank. What is a Thermal expansion tank and why now do I suddenly need one. What is cost?
If your Plumbing Code requires a Backflow preventer, Check Value or Pressure Reducing Valve, You will need an expansion tank.
