Eze-Flow Plumbing is your backflow prevention specialist
Making sure your business is compliant, safe and providing annual backflow certificates
Backflow prevention is a valve or device designed to prevent potentially contaminated water flowing back into the main drinking supply.
On the Northern Beaches, we take for granted the quality of our drinking water. However, there’s still a risk of water contamination before it reaches your tap. On any day, an excavator can accidently dig through a pipe or a water main can burst. When this happens, it creates a back siphon from upstream and in some cases can siphon back harmful bacteria, chemicals or bodily fluids into our drinking water supply. This is why backflow prevention devices were designed, which is effectively a one-way valve that prevents water flowing backwards and allowing contamination back into the main on a siphonic situation.

Where are backflow devices installed?
The simplest device that can be installed to a home irrigation line is an atmospheric vacuum breaker or single check valve. When using garden chemicals such as “Weed’N’ Feed” connected to the garden hose you may be poisoning the property’s water supply. This happens if there’s a drop in water pressure from the main water supply. It causes the chemicals to be sucked back up the line into the property’s water supply.
Sydney Water requires a main backflow device to be installed at the boundary to the property after the meter and to be also installed in any other zones within the property. In a Residential block of units other than the main backflow, devices are required on the fire services, the irrigation hose taps, the bin/rubbish rooms, car wash bays.
How often do they require testing?
Backflow devices must be tested every 12 months. Any time a backflow device is installed by a licenced plumber they must be registered with Sydney Water. If your device has been registered correctly, Sydney Water issues annual reminders and requires the testing of the device to be completed by a specific date. All testing of devices must be recorded with Sydney Water. If you don’t receive letters from Sydney Water it’s likely that your device has not been registered with them and has never been tested. Not to worry, we can test and register your device for you. Contact us today.
