Should I Replace a Hot Water Expansion Tank on My Own?


When your hot water expansion tank needs to be replaced, you may be tempted to do this work yourself.


Far too many people try and often do it incorrectly or dangerously. If somebody isn't licensed to undertake plumbing work in the state of Massachusetts, it's illegal for them to work on your hot water expansion tank replacement.


Reasons You Should Avoid Doing it Yourself

There are several reasons why you should call a professional, some of which we're going to look at now.


  • A Lack of Tools

It's highly unlikely you'll have the right tools for the job. Without the right tools, you won't be able to complete the job to a high quality and run the risk of needing further work in the immediate future.


  • A Lack of Product Understanding

Without an in-depth understanding of the products being used, you're likely to install them wrong and cause more problems with your hot water. Choosing a pro means you get the right equipment for the job each and every time.


  • A Lack of Testing Knowledge

If you're unaware of how to test your hot water expansion tank, you're probably going to end up with something that won't operate as intended or at all. Working with a licensed plumber ensures you get a fully tested and fully functional hot water expansion tank.


  • A Lack of Water Supply

As water expands when it heats up, expansion tanks need to be calibrated correctly to deal with this extra pressure. Only a professional with a water pressure gauge and an accurate reading of the house's water pressure will be able to set the expansion tank to the correct psi. Also, as portable and non-portable expansion tanks are available, it's possible to get something that's not compatible with your system.


  • A Lack of Knowledge on Energy Supplies

If you're not experienced working with gas or electric heating systems, you shouldn't run the risk of causing a serious incident by attempting to work on your hot water expansion tank. There's a reason that people need a license to carry out such work, it's dangerous and can cause major problems.
