Potable Water Expansion Tank Purpose

The tank is partially filled with air whose compressibility cushions shock caused by water hammer and absorbs excess water pressure caused by thermal expansion.

Potable water expansion tank purpose.

Expansion tanks are designed to safely absorb the excess water created and prevent relief valves from triggering. Expansion tanks help reduce water hammer and help protect the plumbing system from stress and damage which leads to longer tank life. When water is heated it expands due to a phenomenon known as thermal expansion. A water storage tank collects water and stores it for later use and timely access.

So when the water pressure gets too high it will flow into your expansion tank instead of damaging your home s plumbing valves fixtures and joints and potentially causing a burst line with immeasurable damages and cost. We offer a range of expansion tanks for potable and non potable applications. It is designed to handle that excess water that builds up. When your water thermally expands a water heater expansion tank prevents unwanted increases in pressure.

And the tanks are finished with appliance quality paint to help prevent external corrosion. These potable water expansion tanks feature a 100 butyl diaphragm and plastic liner to separate the system water from the tanks air precharge. The system has a stainless steel sleeve to prevent corrosion something no other manufacturer offers. If water pressure gets to high it can damage valves in plumbing fixtures joints in supply pipes and the water heater itself.

Reverse osmosis systems work slowly purifying water one drop at a time. Inside the tank has a rubber diaphragm at around the mid point of the tank. Find out more by visiting our website. To do their job these tanks must be properly located sized piped into the overall system and should be checked annually.

Our sizing guide for potable water expansion tanks helps you find the right watts regulator or data potable tank. Water expands by roughly 2 as it heats up from 50 f to 120 f. The expansion tank is designed to handle the thermal expansion of water as it heats up in the water heater preventing excessive water pressure. You install the expansion tank down.

Potable water expansion tanks. An expansion tank or expansion vessel is a small tank used to protect closed water heating systems and domestic hot water systems from excessive pressure. To protect the water heater pipes and other system components from excessive pressure when heating water an expansion tank is added to a water heater.
