Backflow is the reversal of flow of the normal direction of water, in a water supply line. This present a hazard if a contamination or pollution was to be drawn back into the water supply. This has the potential to be harmful or deadly if the pollutant enters the drinking water supply.

This can only occur when the water supply pressure, drops below the plumbing system pressure, for instance a water main burst. To alleviate this occurence a backflow prevention device may be fitted in the supply line.

Legislation requires that backflow devices be teated every 12 months, or incur a $2000 fine.
