What is Backflow Prevention?

A backflow prevention device is basically a device which stops contaminated or polluted water flowing backwards into your usable water. The device allows water to travel in one direction only, eliminating the change of cross-connecting contaminated water into your domestic drinking water.

What can cause backflow?

Backflow can be caused by either back-siphonage or back pressure, and requires a cross connection between the contaminated source and the drinking water supply.

Examples of when back-siphonage can occur include:

  • A garden hose submerged in a swimming pool, tank or pond
  • Blow ground irrigation sprinklers (pop ups) located in low lying areas where surface water ponding occurs

Examples of when back pressure can occur include:

  • Rainwater tank with pressure pump interconnected with the drinking water supply

Why are Back Flow Prevention Devices Required?

Backflow prevention devices are an important component in protecting Hunter Water’s drinking water and are required under Australian Standards for an any premises identified as posing a risk to the public drinking water supply.

Who is Responsible?

Hunter Water’s responsibility is to exercise the required duty of care in the protection of Newcastle’s drinking water supply and to safeguard public health within our areas of operation. This includes ensuring adequate site containment backflow prevention is in place to protect the drinking water supply system.

The property owner is responsible for arranging a licenced and backflow accredited plumber such as Newcastle Plumbing to install, maintain and annually test the backflow device(s) on their property according to all relevant standards and regulations.

Why is Annual Backflow Testing Required?

Each backflow prevention device must be tested annually. This is a legal requirement and a condition of your water supply. Testing ensures that your backflow device is maintained to an acceptable standard and continues to operate effectively. Newcastle Plumbing can perform these tests and send certified reports to Hunter Water for recording.

  • I have had Newcastle Plumbing out to my very old house 5 times now for 5 different plumbing issues and I highly recommend them. Very professional, skilled, efficient and very friendly from the office, the tradesmen, apprentices and of course the boss is hands on as well. Thankyou Newcastle Plumbing

  • Had some renovation plumbing done this morning and couldn’t be happier with the result. Dean and Brendan were punctual, pleasant, and professional. They did a perfect job and tidied up afterwards. Highly recommended.

  • We first used Newcastle Plumbing a few years ago. They were around the next day for a quote and our plumbing was done for our bathroom promptly after ringing them asking when they could book us in. We have since used this company for any plumbing needs, and will continue to do. They are prompt and reliable and have never had a problem with something they have fixed. Highly recommend these guys for anyone wanting a good honest plumber to get the job done right and give an honest opinion.

  • We would never use anyone else but Newcastle Plumbing. They are always prompt, their work is top notch and we are ALWAYS pleasantly surprised at how reasonable the cost has been no matter what we have had done. A very big thank you to Dave for going above and beyond in looking after us (kitchen tap situation) we very much appreciated it and will certainly be calling when we get the new kitchen in.
