Backflow Prevention

Backflow Prevention

A backflow prevention device is used to protect potable water supplies from contamination or pollution due to backflow.
In water distribution systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower, or other fixture. Water pressure may fail or be reduced when a water main bursts, water supply disruptions or there is unexpectedly high demand on the water system (for example, when several fire hydrants are opened). Reduced pressure in the pipe may allow contaminated water from the soil, Gold Coast canals, from storage, or from other sources to be drawn up into the system.
MACRO Plumbing conduct all backflow testing, servicing, repairs and installations as per regulatory requirements.
