How to Tell If an Expansion Tank is Working | Hunker

The hot water expansion tank is a two-gallon tank that hangs off of your hot water system or your boiler. It is used to absorb excess water pressure. When water is heated or a hot water faucet is turned off abruptly, pressure builds from expanding water molecules. Most of the time your tank is half water and half air; it has a diaphragm separating both. When pressure increases the diaphragm is pushed upward.

Water Heater Expansion Tank | How Expansion Tanks Work

An expansion tank prevents pressure increases due to thermal expansion of your water. As your water is heated from 50° F to 120° F, it expands by approximately 2%. If you have a “closed system”, which means there is a backflow preventer or other device that prevents your water from flowing back into the water main, thermal expansion will cause very rapid pressure increases in your plumbing system.

How To Drain the Boiler Expansion Tank - Acme How To.com

As the water in the system is heated, it expands. As it expands, the pressure in the system rises. In order to balance that increased pressure, the expansion tank relieves the system pressure by pressurizing the air. When the expansion tank fills with water, which it naturally does, it reduces the size of the air cushion.
