Did you know that in Australia, property owners have a legal responsibility to install a backflow device if their property is assessed to need it? This is for the protection and conservation of safe drinking water. If any contaminated water from a property was to get into the main water supply, it would be a catastrophe. To find out if your property needs a backflow device read our informative guide.
What Exactly Is Backflow?
Water flow into your property (home or business) is generally maintained at a consistent pressure. This allows water to flow consistently from the shower, tap, or any other fixture. This normal water pressure is reduced when a water main bursts or there is high demand on the water system. Through less pressure in the pipe, contaminated water from your property can be drawn back into the main water supply system. This is called backflow.
Common Causes of Backflow
The following factors are all common causes of backflow:
- Pressure reduction in the water main
- Commercial tenants that may use chemicals or water operated machinery
- Rainwater tank top up units
- Water main burst
- Property’s that have Fire hose reels systems in place
