Why do I need a Break Tank?

Why do I need a Break Tank? – A short guide. A break tank, often referred to as a “Type A Air Gap,” is a vital component in commercial ware washers that prevents the backflow of contaminated water into the fresh water supply. Unlike a WRAS-approved non-return valve, a break tank offers a distinct method of operation.

How BT’s work

Water Storage: Incoming mains water is directed into a separate tank within the dishwasher.

Air Gap: This tank has an open top, creating an air gap that acts as an overflow.

Water Supply: Water is then fed from the tank to the dishwasher.

Backflow Prevention: If a fault causes backflow, contaminated water can only reach the break tank, eventually overflowing through the air gap. This prevents contaminated water from entering the fresh water inlet.

Do You Need one?

UK Water Board Regulations mandate the installation of break tanks (Type A Air Gaps) in commercial dishwashers rated at category 5 risk or higher. This includes high-risk areas like schools, care homes, nurseries, and hospitals. Businesses must assess their risk level and comply with these regulations.

Their location

Typically installed internally within the dishwasher, they ensure minimal impact on performance, operation, or dimensions.

Conclusion

Break tanks are essential for preventing water contamination in commercial ware washers. Understanding their function and compliance requirements is crucial for businesses operating in high-risk environments.
