Potable Expansion Vessels

Find suitable potable expansion vessels for domestic hot water and other compatible potable water systems. Designed for use with drinking water systems, these vessels accommodate changes in water volume and pressure as water is heated or system conditions change.

Potable expansion vessels are commonly used with unvented hot water systems and other suitable applications where expansion of the water needs to be accommodated. The vessel must be suitable for potable water use and correctly specified for the system, including its capacity and operating pressure.
