If polluted or contaminated water gets back into the main water supply it can pose serious health risks so it is important to continually monitor this equipment. Chadoak have been monitoring backflow devices since 1974 and have the experience and equipment to do it right the first time.

The Plumbing Industry Commission has the authority to ensure water users comply with the National Plumbing and Drainage Code. Licensed Plumbers must supply clients with a Certificate of Compliance for plumbing works that include Medium or High Risk Backflow Prevention Devices.

Some Commercial and Industrial sites will already have installed Backflow Prevention Devices at the property boundary, however this will only protect the Water supplier’s main external of your property. A Backflow Prevention Device located directly downstream of the water meter is referred to as Containment Protection.

Backflow may still occur if cross-connections exist on a site, creating a risk of contamination of the drinking water. To prevent contamination of the drinking water on site, Zone or Individual Backflow Prevention Devices are required downstream to hazardous areas such as Mechanical Services plant
