      • Easy install and directions are great!

      • Verified Purchase & Recommended Product

      The thermal expansion tank was very easy to install as were the directions to follow. The thermal expansion tank was a replacement for a unit which was worn out. The tank was a near identical replacement for the exixting unit. I would highly recommend this product if you have a hot water heater that has a back flow preventor installed somewhere in line to allow the water to expand. Othewise you may create a situtation where the pipes may burst due to over pressure.

      Pros Reliable, Easy to Install, Good Instructions, No Leaks
