Sydney Water Backflow Prevention Requirements

A backflow prevention device is something that is fitted to the water pipe on a property to stop the flow of water moving back into the mains water system which can occur if there is a difference or drop in water pressure. If you have backflow water issues there is a risk that potentially contaminated water containing hazardous bacteria and debris could flow back up into your water service. Backflow prevention devices stop backflow siphonage problems by using a;

  • One-way valve
  • An air gap
  • A break tank

Examples of properties or situations where a backflow prevention device is required can  include;

  • Construction sites.
  • Emergency sprinkler or fire service systems
  • Swimming pools
  • Manufacturing facilities.
  • Restaurants or take away shop with a grease trap

Backflow testing ensures the device is working, during a backflow test, we would turn off the downstream shut-off valve, wait a few minutes and test the pressure in the system using a special backflow testing kit. The test is carried out to ensure the pressure is as it should be and the device is functioning.

We helped George’s Chickens take away shop get a backflow prevention device tested. Not every plumber in Sydney is licensed or accredited to install and test RPZ and back flow prevention devices but Nu-Trend is. 


To be able to test and install a backflow prevention device you need extra accreditation that is added to a plumbing license. Quite often Nu-Trend will sub contract for other plumbing companies in Sydney.


Sydney Water have requested a lot of business owners including take away shops to have their backflow prevention devices installed to ensure they are complying with new legal regulations that relate to water lines. 


These Reduced Pressure Zone (RPZ) valves are extremely important to keep contamination or pollution out of the water supply. Specifically, this device is installed onto your plumbing system to protect drinking water and the city water supply.


So we assessed the site to provide recommendations on what was required to make sure the right backflow devices were in place to then submit the report to Sydney Water.

What is backflow PREVENTION testing?

Backflow testing is a process that is used to test your plumbing system to make sure that drinking water is not being contaminated by dirty water infiltrating the water supply.

What is the reason for a backflow ?

Backflow can potentially allow contaminants into the drinking water system. Back siphonage can occur when the pressures from other sources are lower than the water system’s pressure. This could allow an influx, or pulling of contaminated water into the system.

How much does backflow testing cost?

The typical rate for backflow device testing can vary greatly. It depends on your location, the type of device/s that require testing etc The cost can then fluctuate to repair and/or replace the backflow device if found to be faulty.

What does backflow mean?

Backflow is a term in plumbing for an unwanted flow of water in the reverse direction. It can be a serious health risk for the contamination of water supplies with foul water.
