This expansion tank controls thermal expansion of water in open domestic hot water supply systems.
Potable water expansion tank sizing.
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.
Therm x trol expansion tanks are designed to control pressure in commercial closed potable hot water systems.
Let s take some examples.
Examples of one way devices include.

It absorbs the increased volume of water generated by the hot water heating source.
As a rule of thumb a thermal expansion tank should be about 10 of the total water heater volume.
Our sizing guide for potable water expansion tanks helps you find the right watts regulator or data potable tank.
New or larger expansion tanks may be needed due to pressure reducing valves check valves and backflow preventers added to the community s water system.
Backflow preventers.
Its pre pressurized steel tank uses an expansion membrane to prevent air water contact for long system life.
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.
10 5 7 requires backflow prevention to prevent.
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.
100 gallons x 10 10 gallon expansion 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.
