What Does A Water Heater Expansion Tank Do
What Does A Water Heater Expansion Tank Do. When water gets heated up, it cannot compress so it tends to build up pressure as it expands, this is known as thermal expansion. An expansion tank has what’s known as a bladder on the interior of it.

An expansion tank is a small tank divided in two sections by a rubber diaphragm. How to know if you need a water heater expansion tank replacement. If the extra volume has nowhere to go it pushes on the.

When water gets heated up, it cannot compress so it tends to build up pressure as it expands, this is known as thermal expansion. Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature. An expansion tank is a tank that connects to the cold water line that feeds into the tank of the water heater.a rubber baffle separates the two halves of the cylinder.heat from the bladder causes it to expand, pushing the baffle downward into a chamber filled with compressed air, which absorbs the pressure.
