Potable water expansion tank sizing.
Water heater tank capacity is 100 gallons.
This small volume of water can cause rapid increases in system pressure if a backflow preventer or other one way device is installed without the proper thermal expansion tank.
Therm x trol expansion tanks are designed to control pressure in commercial closed potable hot water systems.

It absorbs the increased volume of water generated by the hot water heating source.
The potable water expansion tank shall be installed in the cold water service pipe line on the supply side of the water heater or water storage tank.
Expansion compression and diaphragm tanks for proper system pressurization in hydronic heating and potable water plumbing systems.
Potable water expansion tanks thermal expansion occurs when water is heated during non use periods the installation of a pressure reducing valve prv check valve or back flow preventer closes the water system leaving water with no room for expansion.
This expansion tank controls thermal expansion of water in open domestic hot water supply systems.
