Product description

The expansion tank is designed to absorb the excess pressure that can build up in the water heater tank when the water heats up and expands. Without an expansion tank, this pressure can cause damage to the water heater tank, pipes, and fixtures, and may even cause leaks or ruptures. The 2.1-gallon size is a common choice for residential water heaters, as it provides adequate capacity to absorb pressure fluctuations without taking up too much space.
