Potable water expansion tank sizing.
Backflow preventers.
Sizing the therm x trol potable water expansion tank as water is heated thermal expansion takes place.
Customer support find a watts distributor.
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.
It absorbs the increased volume of water generated by the hot water heating source.
100 gallons x 10 10 gallon expansion tank.
Its pre pressurized steel tank uses an expansion membrane to prevent air water contact for long system life.
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.
500 gallons x 10 50 gallon expansion tank.
Let s take some examples.

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.
This expansion tank controls thermal expansion of water in open domestic hot water supply systems.
Sizing expansion tanks for water heaters can be a complex engineering challenge but residential expansion tank sizing has been simplified through the use of calculators.
Our sizing guide for potable water expansion tanks helps you find the right watts regulator or data potable tank.
Water heater tank capacity is 100 gallons.
Examples of one way devices include.
As a rule of thumb a thermal expansion tank should be about 10 of the total water heater volume.
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.
