City-specific requirements are subject to change at any time. We recommend referring to the authority having jurisdiction for the latest information on when an expansion tank is required in your area.
While expansion tanks are typically only required on closed-loop systems, some cities require them on every new water heater installation. At Legacy Plumbing, we stay in contact with the cities’ building inspection departments and make sure that everything is done up to their standards so that the inspection process goes smoothly.
There are many different manufacturers that make expansion tanks, and there is a great variance in the quality of the materials and the manufacturing processes. There are also a lot of different ways to go about installing an expansion tank on the system. Because expansion tanks are often installed inside homes in or in the attic with the water heater, the risk of water damage if they fail is very high.
At Legacy, we are committed to using the best quality materials and installation practices in order to protect your home. We only use high-quality stainless steel parts and have chosen an expansion tank manufacturer that stands behind its product. We have also refined our standard for installing these tanks so that you can count on it being done right every time.
To avoid excessive pressure in your home’s plumbing system, a thermal expansion tank attached to the hot water heater allows the water within the system to expand and release excess pressure internally. How does that help you? The relief in pressure can help save your system from costly plumbing repairs down the line.
But here’s the kicker about a water heater expansion tank; you can’t install one yourself. This is not a DIY plumbing job. When it comes to an expansion tank for your water heater, hire the professionals at Legacy Plumbing for top-rated expansion tank installation.
