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.

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. When you turn on your kitchen faucet water is carried from the tank to your tap providing you with fresh water on demand. We offer a range of expansion tanks for potable and non potable applications. You install the expansion tank down.

Expansion tanks are designed to safely absorb the excess water created and prevent relief valves from triggering. A water storage tank collects water and stores it for later use and timely access. If water pressure gets to high it can damage valves in plumbing fixtures joints in supply pipes and the water heater itself. 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.

To do their job these tanks must be properly located sized piped into the overall system and should be checked annually. Reverse osmosis systems work slowly purifying water one drop at a time. Pressurized air goes below the diaphragm in the bottom half of the tank and water flows in and out of the top half of the tank. It is designed to handle that excess water that builds up.

The expansion tank s purpose is to protect your house s hot water system from excessive pressure which can cause damage to fixtures your water heater lines and or fittings. Our sizing guide for potable water expansion tanks helps you find the right watts regulator or data potable tank.

The expansion tank is designed to handle the thermal expansion of water as it heats up in the water heater preventing excessive water pressure. When water is heated it expands due to a phenomenon known as thermal expansion. The system has a stainless steel sleeve to prevent corrosion something no other manufacturer offers. Expansion tanks help reduce water hammer and help protect the plumbing system from stress and damage which leads to longer tank life.

When your water thermally expands a water heater expansion tank prevents unwanted increases in pressure. 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. Inside the tank has a rubber diaphragm at around the mid point of the tank.
