Potable Water Expansion Tank Purpose

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.

Potable water expansion tank purpose.

When your water thermally expands a water heater expansion tank prevents unwanted increases in pressure. Expansion tanks help reduce water hammer and help protect the plumbing system from stress and damage which leads to longer tank life. Water expands by roughly 2 as it heats up from 50 f to 120 f. When water is heated it expands due to a phenomenon known as thermal expansion.

Inside the tank has a rubber diaphragm at around the mid point of the tank. These potable water expansion tanks feature a 100 butyl diaphragm and plastic liner to separate the system water from the tanks air precharge. It is designed to handle that excess water that builds up. When you turn on your kitchen faucet water is carried from the tank to your tap providing you with fresh water on demand.

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. You install the expansion tank down.

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. We offer a range of expansion tanks for potable and non potable applications. Reverse osmosis systems work slowly purifying water one drop at a time. The expansion tank is designed to handle the thermal expansion of water as it heats up in the water heater preventing excessive water pressure.

Potable water expansion tanks. Our sizing guide for potable water expansion tanks helps you find the right watts regulator or data potable tank. And the tanks are finished with appliance quality paint to help prevent external corrosion. 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.

The system has a stainless steel sleeve to prevent corrosion something no other manufacturer offers. The tank is partially filled with air whose compressibility cushions shock caused by water hammer and absorbs excess water pressure caused by thermal expansion. 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.
