The functionality of a prevention device is to ensure your water mains are protected from harmful contaminants. Backflow prevention devices have:
- Single & dual check valves
- Vacuum breaker valves
- Reduced Pressure Zone (RPZ) Valves.
What’s the Purpose of a Prevention Device?
Backflow occurs when your water pressure is low to your mains pipework. Water can run backwards like a vacuum into your main water supply when this happens. This has the potential for your to draw in contaminants to your primary source of water, which can be anything from:
- Irrigation systems
- Liquids hoses have been sitting in
- Sewage
- And more.
How Regularly Should Backflow Devices Be Tested?
A yearly check of your backflow prevention device is required. Doing so with this regularity ensures it’s working correctly and meets Queensland’s state legislation and council regulations. Testing must be completed by licensed plumbers that have the added qualifications for backflow prevention. Once tested, a report is issued to your local council for certification.
Cost of Backflow Testing
The cost of testing your backflow prevention device will vary depending on how many you have, whether it needs replacing or if there is an actual backflow issue. We recommend our Gold Coast backflow testing team directly to discuss your needs and the associated costs.
