Whether your property is required to meet council or Sydney Water regulations, or you’re simply looking to improve safety, we ensure the right solution is in place and operating as it should.
Backflow issues can occur when water pressure changes, allowing contaminated water from irrigation systems, industrial equipment, or other sources to flow back into the clean water supply.

How Backflow Prevention Works
Backflow prevention is about protecting the clean water that comes into your property. It stops contaminated or non-potable water from flowing backwards into the local water supply.
This is important because pressure changes, like a burst main or heavy usage, can cause dirty water, chemicals, or other contaminants to end up in the drinking water system.
In Thornleigh, all properties connected to the public water supply must have a backflow prevention device that meets Sydney Water’s strict standards. Our team at JSW Plumbing installs and maintains these systems to protect your home or business and keep you compliant.
Common Backflow Risk for Thornleigh Properties
Many properties in Thornleigh face backflow risks, especially those with pools, irrigation, or commercial activities. Cross connections, where drinking water lines meet potential contaminants, are a primary hazard.
A faulty garden hose in a pool or a misconnected rainwater tank can create serious issues. Our team identifies these cross connections and implements the right prevention solution for your setup.
Devices and Legal Compliance for Backflow Prevention
Sydney Water requires different backflow devices depending on your property’s risk level. Low-risk areas use simpler vacuum breakers, while higher-risk sites, like medical facilities or those dealing with chemicals, need certified double check valves or reduced pressure zone devices.
Every installation and annual test must be completed by a licensed plumber, and all results are logged with Sydney Water.
JSW Plumbing’s technicians handle selection, installation, maintenance, and all compliance paperwork so you skip the stress and stay protected.
Maintenance and Annual Testing for Backflow Devices
Thornleigh regulations require every testable backflow device to be inspected at least once a year. This keeps the system reliable and ensures your property’s compliance. If issues are found, they must be fixed straight away and reported through official channels.
When we service your property, we handle all test results and records for you, so everything’s up to date and fully traceable.

How We Install Backflow Prevention Devices
Understanding backflow prevention devices is crucial for maintaining a safe and compliant water supply in Thornleigh. Our team at JSW Plumbing is familiar with the unique standards and regulations that govern backflow prevention in both domestic and commercial properties. We regularly work with Sydney Water guidelines and the Australian Standards to ensure every device installation meets hazard ratings and compliance protocols.
Hazard Ratings Direct Device Choice for Backflow Containment
Each property in Thornleigh is assigned a hazard rating: low, medium, or high, which determines the type of backflow device required. Only accredited plumbers can assess these ratings. If a hazard is uncertain, a high-risk category is applied by default.
Our backflow plumbers make sure the device matches your site’s exact backflow risk, which is critical for council sign-off and your ongoing compliance.
Double Check Valve vs Reduced Pressure Zone Device
Different backflow preventers serve different risk levels. Testable double check valves are typical for medium-risk sites like apartment blocks and commercial kitchens.
High-risk areas, such as certain medical or chemical sites, require reduced pressure zone device or air gaps, installed to strict guidelines and with WaterMark™ certification. For most Thornleigh homes, a non-testable dual check valve is enough, usually fitted at toilets or the meter. We handle everything, from selection to annual testing and documentation.
Mandatory Testing, Certification, and Ongoing Maintenance
Annual testing of devices like RPZDs and testable double check valves is required by law in Thornleigh. Our licensed team conducts thorough checks, files certificates electronically with Sydney Water, and ensures each repair or modification is retested before use.
This diligence protects your property from non-compliance penalties and secures your water supply from contamination. Our attention to detail and up-to-date knowledge mean you can rely on JSW Plumbing for safe, compliant backflow prevention in Thornleigh.

How Backflow Prevention Services Protect Your Water Supply
Backflow prevention services offer a range of critical benefits for homes and businesses. Our team focuses on practical solutions that deliver health, safety, and peace of mind, all while meeting local compliance standards.
Protects Your Drinking Water from Contamination
Backflow prevention works by stopping contaminated water from entering your main supply due to sudden pressure changes. Events like pipe bursts or hydrant use can cause this risk without warning.
We make sure your backflow devices are installed and maintained to keep your water safe from pollutants and bacteria.
Ensures Compliance with Sydney Water Regulations
Sydney Water requires every property to have the proper backflow prevention device installed, with annual testing signed off by accredited plumbers. Our licensed team can assess your site, install compliant devices, and carry out backflow test so you avoid fines or supply interruptions.
We handle the paperwork and reporting to Sydney Water on your behalf.
Reduces Owner Liability and Risk
If backflow leads to contamination and harm, property owners can face heavy penalties and liability claims. By using our professional backflow prevention services, you can show that you’ve met due diligence and have a documented maintenance record, providing valuable legal and financial protection.
Matches Protection to Your Property’s Risk Level
Different sites need different levels of protection, from basic single check valves to high-grade devices for industrial or healthcare sites. We accurately assess your property’s hazard level, supply a suitable backflow solution, and maintain it as regulations change.
This means tailored, reliable protection rather than a generic approach.
To better protect your property and meet all requirements, get in touch with JSW Plumbing for straightforward, quality backflow prevention support.
How We Handle Backflow Prevention
We take backflow prevention seriously because water safety is non-negotiable. Here’s how our team works to keep your property compliant and your water supply protected.
Assess Your Property Risk
Our first step is always a proper assessment. We look at your plumbing, property use, and any added features like rainwater or greywater systems to determine what level of backflow device is needed under Sydney Water rules.
Run Annual Testing and Compliance
Every year, we test your backflow prevention device and log the results to keep your property compliant. If anything’s off, we’ll talk you through your options and sort any repairs or replacements as needed.
Conduct Repairs and New Installations
When repairs make sense, we handle them fast to get your device back in top shape. If a device can’t be repaired or does not meet standards, we’ll install a new one that matches your hazard rating and site needs.
Handle Certification and Reporting
We handle all compliance paperwork and lodge test reports with Sydney Water as required. This keeps your property records up to date and avoids compliance headaches down the track.
Offer Ongoing Device Maintenance
We offer reminders for annual testing and keep an eye out for developing issues. This helps prevent sudden failures and ensures your backflow system continues to protect your water supply.
