Did you know, by law, a boundary Backflow Prevention device must be checked annually by a qualified and licensed plumber?
Backflow occurs when water from a customer’s property flows backwards into our pipes. This may carry contaminants that can harm people’s health.
The problem is more likely to occur if:
- There’s a drop in pressure in the main, eg during a main break
- Water pressure at the property is higher than at the main, eg if a pump is operating on the site.
Backflow Prevention Device
These devices ensure our water supply isn’t contaminated from hazards on a customer’s property.
They stop water in a customer’s water pipe flowing back into our water main.
Strong plumbing regulations and Plumbing and Drainage Standards are in place to protect our potable water supply from contamination which can occur when chemicals and other contaminants are drained back into our water distribution system.
We can carry out the following services for you
Annual backflow prevention testing, inspections and maintenance reports
Installation of backflow prevention devices/valves selected in compliance with Australian Standards
We are happy to conduct a review of your backflow prevention devices to ensure you comply with regulations. Contact us on 02 4656 4064 for an appointment.
Why Do Properties Need Backflow Prevention Devices?
Not every property requires a backflow prevention device. However, if there is a medium or high risk of contamination entering the drinking water supply, Sydney Water may require one to be installed.
Common examples include:
- Commercial and industrial properties
- Medical and dental facilities
- Irrigation systems
- Fire sprinkler systems
- Properties using chemical injection or water treatment equipment
- Sites with pumps, tanks or alternative water supplies
If you’re unsure whether your property requires a device, we can inspect your plumbing system and provide the right advice.
Installation, Testing and Ongoing Compliance
Installing a compliant device is only the first step. Most registered devices must also be tested every year by an accredited backflow plumber.
We can:
- Install compliant backflow prevention devices
- Test existing devices
- Carry out repairs where required
- Lodge the required test reports with Sydney Water
- Provide reminders when your next annual test is due
Keeping your device maintained helps protect the public water supply while ensuring you remain compliant with current regulations.
