Backflow Device Testing


What is a backflow prevention device?

Commonly known in the plumbing industry as a Reduced Pressure Valve (RPZ), a backflow prevention device is used to protect the water supply from contamination or pollution.


When water pressure is significantly reduced, or fails entirely (as can be the case when a water pipe bursts, for instance), it has the potential to allow contaminated water from the ground, or untreated water from a storage unit, to find its way back into the potable water system.


However, a backflow device will prevent this from happening and protect the water supply so that it remains safe for consumption.


The installation of a backflow prevention device is required to comply with Australian Standard AS/NZS 3500.1, and needs to be undertaken by a licensed plumber with backflow accreditation. At Jack the Plumber, we are proud to say that we have this accreditation and are therefore qualified to undertake the installation of backflow devices.


Annual Backflow Prevention Device Testing

In addition, these devices also need to be tested each year by a plumber with the appropriate license and accreditation. We are able to undertake this annual testing on behalf of the Office of the Technical Regulator (OTR) in South Australia, and to submit all of the accompanying documentation that is required.


Annual back flow testing is a requirement under South Australian law for all high and medium hazard back flow prevention devices, and property owners who do not submit their devices to this testing can have action brought against them by their local council or the OTR.
