What is Backflow and Why Does It Matter for Your Water Supply?
You turn on the tap expecting clean, safe water, but have your ever wondered what stops dirty or contaminated water from flowing back into your home's supply? That's where backflow prevention devices come in. They quietly protect your water supply every single day - and when they're not working properly, the risk can be bigger than most people realise.
What Exactly is Backflow?
Backflow happens when water flows in the opposite direction to where it should. Instead of clean water flowing into your property, contaminated water flows back into the main water supply.
This can occur if there's a sudden drop in pressure in the mains (for example, a burst water main or a fire hydrant being used nearby). When that happens, water from your property can be sucked back into the main public supply - carrying chemicals, bacteria, or other contaminants with it.
The Role of a Backflow Prevention Device / Valve
A backflow prevention device, or valve, acts like a one-way gate. It ensures that water can only flow in one direction - into your property. These devices are essential for any premises where there's a potential risk of contamination, such as:
- Commercial kitchens and cafes
- Hairdressing salons
- Medical or dental clincs
- Funeral homes
- Petrol stations
- Schools
- Day Care facilities
- Car yards
- Panel shops
Why Testing is So Important
Just like smoke alarms, backflow devices need regular testing to make sure they're still working as they should. Over time, parts can wear out, valves can stick and seals can fail. In Victoria, backflow prevention devices must be tested annually by a licensed plumber who is accredited for backflow prevention.
