What is Backflow Testing in Commercial Plumbing?

It is legally required for businesses in Australia to conduct a backflow test annually, by a licensed plumber. This is because although backflow prevention devices are highly useful, they, like all technology, can fail or may need repairs. In this article, we explore what backflow testing is, and why you should make it part of your plumbing routine.

What is backflow testing?

Backflow testing is a process that ensures contaminated water is not entering the water supply of a plumbing system. This may occur as a result of water pressure. Whilst our pipes are kept at a standard pressure to allow water to flow through, a sudden drop of pressure, due to a burst or frozen pipe, or a sharp increase in water usage, may allow contaminated water to enter the system. Instead of flowing in the right direction, it will flow backwards – which is how the water will become contaminated.

Backflow testing not only checks whether the water is safe and drinkable but also how well backflow is being prevented in an area.

How to prevent backflow

There are several routes you could take when aiming to prevent backflow. The first is through the use of an air gap, which involves leaving a space between the spaces where water might accumulate and the valves and faucets present in your plumbing system.

Using a backflow prevention device, such as a backflow preventer valve, is another possible way you could prevent backflow. By installing the valve in locations where there is a risk of contaminated water flowing into your system, you reduce the chances of backflow occurring.

Is backflow testing important?

Business owners are legally obligated to have an annual backflow test performed at their buildings, by a certified plumbing company. This testing process will take up to thirty minutes to complete. It involves testing valves by opening and closing them, and then submitting a form to the local water authorities outlining that there are no irregularities or code violations. If there is backflow present, the plumbers will investigate what is causing it and repair it.
