Backflow Responsibilities and Your Legal Responsibility When Managing Property

Did you know that in Australia, property owners have a legal responsibility to install a backflow device if their property is assessed to need it? This is for the protection and conservation of safe drinking water.  If any contaminated water from a property was to get into the main water supply, it would be a catastrophe. To find out if your property needs a backflow device read our informative guide.

 

What Exactly Is Backflow?

Water flow into your property (home or business) is generally maintained at a consistent pressure. This allows water to flow consistently from the shower, tap, or any other fixture. This normal water pressure is reduced when a water main bursts or there is high demand on the water system. Through less pressure in the pipe, contaminated water from your property can be drawn back into the main water supply system. This is called backflow.

 

Common Causes of Backflow

The following factors are all common causes of backflow:

  • Pressure reduction in the water main
  • Commercial tenants that may use chemicals or water operated machinery
  • Rainwater tank top up units
  • Water main burst
  • Property’s that have Fire hose reels systems in place

What is a Backflow Device?

This is a device designed to stop water from flowing in the reverse direction and contaminating mains and drinking water. A fully accredited backflow prevention plumber is required to assess, install, commission and test your device. Several Australian states have bought in legislation that requires backflow devices are checked every 12 months (tested and certified). Check your state’s requirements or ask your plumber. A faulty device can contaminate the water supply and cause illness and even death.

 

Do I need a Backflow Device?

This depends on the hazard rating of your property and the state in which your property is located. Different states have different legislation. The relevant water authorities in your state along with a licensed plumber can help to assess the hazard rating. If a backflow device is needed than it must be installed at the water meter, or all meters if there is more than one. There should be no connections between the water meter and the device.

 

Property Owner Responsibilities

Under Australian legalisation property owners have the responsibility to ensure that backflow does not occur at their property. As a property owner, your responsibilities are:

  • Install a backflow prevention device (if required, no avoidance).
  • Be concerned about the drinking water supply on your property (report any potential hazards).
  • Hire an accredited backflow prevention plumber to assess, install, commission and test your device.
  • Ensure your plumber installs the correct device for your property (different devices needed for different property types).
  • Get your device tested yearly by the right plumber
