BACKFLOW PREVENTION

Cross connections are the links through which it is possible for contaminants  to enter a water supply. Backflow occurs when the water flows in the opposite direction to which it is originally intended to flow.  Back flow of water, via cross connections, allows contaminates to flow back into the water system and can threaten the safety of our drinking water.  Backflow prevention devices are necessary to prevent this backflow, and ultimately contamination, from occurring.

 

As a business owner, it is your responsibility to have a licensed and certified plumber not only assess your level of risk and install a backflow prevention device, but also to have these devices tested and serviced annually and to notify the relevant water authority that this has been done.

 

Failure to do so risks water supply contamination.  This can lead to gastrointestinal illness, exposes yourself and/or your business to liability and may also result in your water supply being shut off by the regulating water authority in order to protect others sharing the same water system.

 

WDFA Plumbing Solutions are one of only a small number of licenced plumbing business that are certified in backflow prevention.

  • A hazard rating of low, medium and high is applied to a premises as defined by the plumbing code of Australia 2019 and the Australian/NZ standard AS/NZS 3500.1 2018.  This rating determines which backflow prevention device is needed, and is dependent on the location of a property and the services provided by that premises/business.
