What Is Backflow Prevention?

You might be asking yourself, “Why do I need a backflow preventer?” The simple answer: to keep your water safe.

Backflow occurs when water reverses direction in a plumbing system, allowing contaminants from wastewater or chemicals to flow into the potable water supply. A backflow prevention device stops this from happening. It ensures that water only flows in the correct direction, keeping pollutants out of your drinking water.

In Sydney, all connections to water and recycled water systems must be fitted with a backflow prevention device. This is mandatory by law to protect public health.

How the Backflow Prevention Device Works

When Backflow Happens

Backflow occurs when water flows in the wrong direction, usually due to a drop in water pressure. This can happen if there’s a burst pipe or a sudden change in water demand. When this happens, contaminated water from systems like sewage, irrigation, or chemicals can flow into your clean water supply.

How the Device Prevents Contamination

A backflow preventer is a one-way valve installed in your plumbing system. Under normal conditions, water flows freely through your pipes. But when backflow is detected, the valve automatically shuts, stopping any contaminated water from flowing into your system and protecting the clean water supply.

Types of Backflow Prevention Devices

There are various types of backflow preventers depending on the level of protection needed. Reduced Pressure Zone (RPZ) valves are commonly used for high-risk situations, while Double Check Valves provide a lower level of protection. The right device depends on your property type and risk level.

Why Is Backflow Prevention Important?

Contaminated Water Supply

As mentioned previously, if backflow occurs, hazardous substances such as bacteria, chemicals, and debris from wastewater systems can contaminate your water supply. This can lead to serious health risks, including waterborne diseases.

Legal Penalties

Failure to install a backflow prevention device can result in legal consequences. Under AS/NZS 3500.1:2021, all property owners are required to comply with the standards. Not doing so could result in hefty fines and legal penalties.

Infrastructure Damage

Backflow can damage your plumbing system over time. If contaminants enter the pipes, they can cause corrosion and other issues that lead to expensive repairs. Avoid these problems by having the proper devices installed from the get-go.

Environmental Impact

When contaminants from wastewater systems enter natural water bodies, they can pollute local rivers, lakes, and oceans. This harms aquatic life and disrupts ecosystems.

The Australian Standard for backflow prevention is AS/NZS 3500.1, which we strictly follow for all of our services. This standard ensures that backflow systems meet safety and legal requirements. The risk level of the property determines the type of backflow prevention device required. Here’s a quick breakdown of risk levels:

Low Risk: No significant health hazard if backflow occurs. Examples: hair salon sinks, irrigation systems.
Medium Risk: Potential health risks if backflow occurs. Examples: public swimming pools, caravan parks.
High Risk: Serious health risks if backflow occurs. Examples: waterfront facilities, sewage treatment plants.

Installing a backflow preventer requires professional expertise. To comply with local regulations and ensure the device works properly, you must hire a licensed plumber.

A well-maintained backflow prevention device can last 5 to 10 years on average. Regular testing and proper care can help extend its life and ensure it functions correctly.

Backflow prevention devices must be tested annually to ensure they function correctly. Regular testing helps detect any issues early, preventing more serious problems. This testing is required by law to maintain compliance and protect your water supply.

If your backflow preventer fails the annual test, it needs immediate attention. Our team can inspect the device, identify the issue, and recommend repairs or replacement. This ensures your system stays compliant and your water supply remains safe.

A Double Check Valve (DCV) is a basic backflow preventer, ideal for low to medium-risk properties. It uses two check valves to prevent backflow.
An RPZ valve offers higher protection, using a pressure differential to keep water flowing in one direction. It’s used in high-risk areas, like commercial or industrial properties, where contamination is at higher risk.

Decreased water pressure
Water discolouration or unusual smells
Inconsistent water flow

If you notice any of these signs, it’s time to have your system checked.

Backflow preventers are primarily designed to stop contamination from wastewater systems. They will not be effective against stormwater contamination.

Backflow preventers are primarily designed to stop contamination from wastewater. For highly toxic or industrial substances, you need additional safety measures or more advanced backflow protection systems.

Sydney Water requires all properties connected to the drinking water supply to have appropriate backflow prevention devices to prevent contamination. According to the Water Supply (Safety and Reliability) Act 2008, backflow connections must meet specific plumbing standards. Non-compliance can lead to enforcement actions, including fines and potential disconnection.

Local councils also enforce compliance. For example, the Tenterfield Shire Council can disconnect or restrict water access if backflow prevention requirements are not met, ensuring safety and compliance.
