      Answer This Question

      A:  That really depends on your system as they are all different. Some systems are designed and installed to make this easy. They, like mine, have an isolation valve that allows you to close off the expansion tank. With those you can then unscrew the old tank and screw in the new one. However, most are not set up with maintenance in mind. So, you need to take significant water out of the system before you can replace the tank. Then you need to replace the water and more importantly purge out all the air. I don’t find this daunting but then again, I have done it before. The answer to your question depends on your system and your knowledge relative to the principles of a hydronic heating system. Let me add if are unfamiliar with how these systems work and unscrew the old tank water is going to come out under pressure, and that water could be dangerously hot if the system is up to temperature. If you are unfamiliar with how to change a tank, I would suggest you contact a local qualified licensed plumber. Chris 978 651 3301

          High quality replacement, same as originally installed on my oil burner / hot water heating system when house was built about 16 years ago. Bladder broke in old one so tank filled with water. Pressure relief valve on system was discharging water. Easy to replace, just remember to relieve the pressure in the system before unscrewing the old tank (oops).

            Would it be possible for HomeDepot to FIX my account so I can actually manage my payment/CC information, Maybe *BEFORE* they get hacked and someone steals all the information?

                great item, still made in USA! FAST shipping !
                My 30 year old tank started to malfunction, same as this one, so i wanted to purchase the same one. The only way was to get it on line, so i purchased it on Friday morning, shipped in the afternoon and i received it before 10:30 am on Saturday! Worked as designed and hopefully it last the 30 years that my last one did.
