Backflow Prevention Test and Certification

Backflow is a term used to describe a situation in which potentially contaminated water flows in the opposite direction to that intended and enters the drinking water supply. A drop in supply pressure normally causes Backflow, creating a negative pressure in the water supply system. This allows contaminated liquid to be siphoned into the drinking water via a cross-contamination. The consequences of Backflow range from being a nuisance to the very serious, even to the extent of causing death of an unsuspected person drinking from the contaminated water supply.

Testing and Certification is a requirement and must be done annually to prevent contaminants reaching your drinkable water as per AS/NZS3500.
