Discovering Backflow Prevention Testing in Canberra and Queanbeyan

Backflow Prevention Testing in Canberra with JML Plumbing and Gas.

Are you curious about what backflow prevention testing is and why it’s essential for your property in Canberra and Queanbeyan? Let’s delve into the world of safeguarding your potable water supply from contamination and how JML Plumbing and Gas can help ensure the safety of your water.

What is Backflow Prevention Testing?

Backflow prevention is a critical measure to shield your drinking water from potential pollutants that could pose a significant health risk. Properly installed and well-maintained backflow prevention devices are the frontline defenders, ensuring that water flows in only one direction, especially in areas where known hazards exist. This process not only safeguards the residents within your property but also protects the Icon Water street mains.

How Often Should You Test a Backflow Preventer in Canberra?

In accordance with regulations, any testable backflow device must undergo testing every 12 months. This critical task should be performed by a licensed plumber accredited in backflow prevention. It ensures that the device operates optimally and can identify if any valve requires servicing or repair. Following testing, the licensed plumber must submit a certificate to Access Canberra, the plumbing regulator, which becomes part of the property’s building file.

Responsibility for Backflow Prevention Device Testing

It falls on the shoulders of building and device owners to ensure the backflow prevention valve is tested every year. Neglecting this responsibility could result in fines imposed by Access Canberra or, in extreme cases, a disruption of your water supply until the hazard is addressed. Most importantly, non-compliance can put people at risk of consuming contaminated drinking water.

Notification for Backflow Prevention Device Testing

BEPCON, also known as Access Canberra, will send notifications when your backflow device is due for testing. Expect to receive 2 to 3 automatic reminders to stay on top of this essential safety requirement.

Consequences of Neglecting Backflow Device Testing

Failure to adhere to backflow prevention legislation, including annual valve tests, could result in fines or even the suspension of water supply to your property. Beyond the legal repercussions, not testing your backflow device endangers the health of those relying on your water source.

Backflow Prevention in Different Building Types

Residential Single Dwellings (Freestanding Houses)

In most cases, freestanding houses do not require a testable backflow device unless specific hazards, such as underground rainwater tanks or commercial water appliances, are present.

Residential Strata Dwellings

Larger strata buildings typically have multiple testable backflow devices. Smaller complexes may have at least two, but certain circumstances may exempt them.

Commercial Dwellings

The backflow hazards in commercial buildings vary significantly based on their specific purpose, making it challenging to provide a one-size-fits-all description.

Where to Find Backflow Prevention Devices in Canberra

There are three key locations for backflow prevention devices:

  1. Containment

Installed after the incoming water meter and before the first branch in the waterline, a containment device provides a second layer of protection for the water mains. However, it does not directly safeguard residents within the building.

  1. Zone

A Zone backflow prevention device is designed to protect multiple hazard points with a single valve. Anything downstream of this device is considered non-potable water, ensuring resident safety.

  1. Individual

Installed at the point of hazard where a single fixture connection is located downstream, the Individual device safeguards residents from potential hazards.

Scenarios Where Backflow May Occur

Backflow incidents can happen for two primary reasons:

  1. A sudden drop in water pressure, often due to pipe bursts, can cause water flow reversal, pulling contaminants into the pipework.
  2. Connecting two water supplies, such as treated greywater or rainwater alongside mains water, may lead to backflow if not adequately serviced.

Assessing Hazard Levels

Identifying backflow risks involves assessing their hazard level, categorized as Low, Medium, or High based on potential outcomes. These assessments adhere to the Plumbing Code of Australia and Australian Standards AS3500.

Types of Backflow Prevention Devices in Canberra

Three primary backflow prevention devices are commonly used in the ACT:

  1. Double Check Valves (Medium and Low Risks)
  2. Reduced Pressure Zone Devices (High Risk)
  3. Registered Air Gaps (High Risk)

Non-Testable Backflow Devices

Non-testable backflow devices operate similarly to testable ones but lack mechanisms for testing their functionality. Over time, like tap washers, the seals within non-testable devices wear out and require servicing. They are not suitable or legally approved for protecting public water supplies against medium or high hazards.

One example of a non-testable device is a dual check valve commonly found in 20mm residential water meters in the ACT.

Safeguarding your water supply through regular backflow prevention testing is essential for public health and compliance with regulations.
