Backflow

What is Backflow?

Backflow is when water flows backward into the public water supply network. This is caused when water pressure drops in the water distribution system causing water to flow in the opposite direction, from residential or commercial premises, back into the public water supply network. Contaminants could be back-siphoned or injected by back-pressure into the public water supply; or a combination of both, where cross connections exist.

Preventing Backflow.

Preventing water contamination from backflow is easy. All you need to do is install a boundary backflow prevention device at the service connection/s and have the device tested annually. This device, when maintained and working properly, will trap water that begins to flow the wrong way and prevent contamination of the public water supply.

We are I.Q.P certified so can test and service your device and save you the hassle and we can come to your site and test each device at a time suitable to you.

Once our testing is complete we’ll keep your test details. We can also put you on an annual device testing recall so that your testing requirements will be scheduled for you. If your device is working correctly, we will approve your backflow device for use for another year. If our test indicates that your device requires repair, you will be notified in writing outlining what you need to do to fix the problem. We can arrange any repairs and then book re-tests.

The cost for an annual test is dependent on the number of devices at your property. Call our service team

  • B & B Plumbers have done excellent work. Especially S**, who worked hard under three units on his own. She also acknowledges Scott who helped on the job from time to time too. Fabulous workmanship, lovely and polite young men. They worked for hours and hours to fix her copper pipes. Now there is no noise from the neighbours toilet flushing or from other neighbours using their washing machines. She appreciates all their hard work and knows it was a big job. PATRICIA - May 2018
