A backflow prevention device prevents the reverse flow of water and protects drinking water quality from contamination.
When you need a device
A backflow prevention device is required on your property if you have:
- an irrigation system
- fire hose reels or hydrants
- commercial or industrial activity
- machinery connected to the mains.
Council is required to maintain a register of backflow prevention devices under the Plumbing and Drainage Act 2002. The device must be inspected or tested by a licenced plumber at least once a year.
- A registration fee is payable for a backflow prevention device (payable at installation).
- An annual registration fee payable for all devices on properties.
