Backflow Prevention Experts in Sydney

Unfortunately, backflow is a common problem for Sydney homeowners and businesses. It is potentially a serious and dangerous problem that results from water flowing in the opposite direction to normal through pipes and plumbing systems.

There are a number of reasons why this can cause a hazardous situation but one of the most common is when a water supply is connected to a source of pollution. The result is that heavy metals or other pollutants can enter your supply without your knowledge.

You might not notice it, but over time, this backflow brings up water pollution and chemicals back the other way into your water system and your home.

Installing Backflow Prevention Devices

Here are some steps to take when installing backflow prevention devices. Firstly, you must get an accredited backflow plumber to install the right kind of device. Secondly, the plumber must also appraise your site’s hazard rating and test your backflow device. Once a test has been done, backflow plumbers must send the test report to Sydney Water using the online lodgement system. Thirdly, you’re responsible for ensuring your plumber sends a certificate of compliance when they install high/medium hazard devices.

Finally, your plumber will use Sydney Water’s online lodgement system to submit your backflow test report. Thus, Sydney Water will remind you when it’s time to get your backflow device proved each year. After Installations, only licensed plumbers with backflow prevention accreditation can inspect, commission, and test backflow devices.

Hazard Ratings

You must employ an accredited backflow plumber to assess your site’s hazard rating. The hazard rating needs to be assessed every time site activities change. The hazard rating of the site’s processes determines which category of device you need to install.

Make sure to tell your plumber if your property has more than one connection to a water main. This is because this may affect your hazard rating and the type of device the plumber must install. If the hazard rating varies due to multiple processes, you must apply the highest hazard rating.

Getting a registered break tank, reduced pressure zone or registered air gap installed is a must if your property has an unknown hazard rating. Residential, commercial & industrial properties that have a medium-high hazard rating need an approved, testable backflow prevention device installed at the outlet of the water meter.

Backflow device types

Reduced pressure zone device (high hazard rating)

In the first place, this device has two independent actions, non-return valves. Not to mention, these valves are force-loaded to the closed position. Uniquely, a relief valve is positioned between the non-return valves. Similarly, this is arranged to be force-loaded to open to the atmosphere.

Break tank / Air gap (high hazard rating)

This device has an air brake (physical gap). This gap is located between the lowest water service pipe outlet and any upstream tank, fitting, or container.

Testable double check valve (medium hazard rating)

This valve has two independent action, non-return valves, and is force-loaded to the closed position. It is also fitted with three test taps for yearly testing.
