Backflow Prevention

Backflow Prevention Canberra

If you have landed on this page, you may have a registered and serviceable backflow prevention device which is at your property!

Access Canberra will typically send a reminder to the owner of the property, facility manager or property manager that holds the backflow prevention device to let them know it requires an annual service. The valves within the backflow prevention device require testing yearly to ensure that they are functioning as the manufacturer intended. The backflow prevention device is there to protect you and others, from receiving contaminated water in our potable water or clean water source, i.e. the Government water supply. The term backflow could have several circumstances where back siphonage occurs from the loss of pressure or cross-contamination with the plumbing. What happens is either a reversal of water flow in the pipework, or the government’s main water supply can drop in pressure resulting in back-siphonage from a burst pipe or blockage in the equipment. If there is a cross-connection or chemical connection to the plumbing, a situation of hazardous liquid may enter the general public or your fresh potable drinking water; this would be even worse if there is no backflow device fitted. If there is no backflow prevention device fitted, it may go unnoticed until someone or a product is directly affected by this.

Some examples of organisations that require backflow devices are; Domestic house rainwater harvesting systems, hospital medical dental and age care properties. Sporting complexes, retail complexes, hotels, motels, caravan parks, agricultural centres, car washing facilities and factories.

The prevention of water pollution is not necessarily something that people consider when dealing with plumbing maintenance, but it is essential. Cross-contamination of water from a potentially polluted source (backflow) is not just unpleasant; it can be incredibly hazardous to your health. This contamination can occur when the water supply on a property is inadvertently interconnected with a source of polluted water, whether through cross-connection, a burst main, or a submerged hose. Any contaminants contained within the source then have the potential to enter your property’s drinking water whenever there is a sudden drop in the mains pressure or an excess of pressure from the property itself.
