Expansion Tanks

An expansion tank in a plumbing system is a crucial component designed to deal with the thermal expansion of water. When water is heated it expands in volume, this expansion can create pressure within the system. The expansion tank serves to absorb this increased volume of water and prevent pressure buildup that could lead to damage or failure of pipes, fittings, or fixtures.
