A safe and clean water supply is a fundamental requirement for every household. Unbeknownst to many, backflow issues can pose a significant threat to water quality and safety. In this article, we'll delve into backflow prevention, outlining its importance, the type of backflow devices to be installed, and how to ensure continued protection with the help of plumbing and fire experts.
What Is Backflow?
Backflow is the unwanted reverse flow of water that may contain contaminants, polluting the clean water supply. It can occur due to backpressure or back siphonage. Backpressure occurs when the water supply has lower pressure than the plumbing system, while back siphonage occurs when negative pressure in the supply line draws water from a potential source of contamination. Both these instances can lead to serious health hazards and require immediate action to prevent contamination of your potable water supply.
The Basics of Backflow Prevention
Backflow prevention is the use of devices and practices aimed at safeguarding your water supply from potential pollutants. A backflow prevention device is installed at the point where a potential source of contamination connects to the potable water system. This barrier restricts any reverse flow of water, ensuring that contaminants don't find their way into your clean water supply.
Types of Backflow Prevention Devices
There are various types of backflow prevention devices, and the selection depends on the level of risk and the requirements of your specific plumbing system. Some common backflow devices include:
- Air Gaps: An air gap is a physical separation between the water outlet and the flood level of a fixture, ensuring no direct connection between potable water and potential contaminants.
- Dual Check Valves: Dual check valves consist of two spring-loaded check valves in one device. They are typically used for low-hazard applications with a low risk of contamination.
- Reduced Pressure Zone (RPZ) Devices: RPZ devices are used for high-hazard scenarios where the risk of contamination is significant. They consist of two independently acting check valves with a pressure-relief valve situated between them.
- Atmospheric Vacuum Breakers (AVB): AVBs are designed to protect your water supply from low-hazard contaminants by venting a downstream valve to the atmosphere when there is a siphoning effect.
Proper Installation and Maintenance
To ensure the effectiveness of your backflow prevention device, it is crucial to have it professionally installed and maintained. Licensed plumbers, such as those at Mid Coast Plumbing and Fire, are trained to correctly identify and assess backflow risks, recommend suitable devices, and ensure proper installation.
Regular inspections and maintenance are vital to maintaining the device's functionality. Over time, components can wear out, seals may degrade, and springs may lose tension. Scheduling periodic inspections will help identify any potential issues that could lead to a malfunctioning device.
Legal Requirements and Compliance
In Australia, backflow prevention devices are subject to strict regulations and compliance requirements. Local government authorities and water utilities may enforce specific rules, including the installation of approved devices and the testing frequency. It is your responsibility as a property owner to ensure that your plumbing system complies with the relevant regulations, with penalties possible in cases of violation.
Signs Your Backflow Prevention Device May Need Servicing
It is essential to remain vigilant and schedule professional maintenance if you notice any of the following signs:
1. Reduced water pressure or inconsistent flow
2. Water discolouration or foul smell
3. Recurring instances of plumbing system backups
4. Visible leaks or corrosion in the device components
