Professional Backflow Device Installation & Upgrades

The specific type of backflow prevention device you need is entirely dependent on the hazard rating assigned to your property by the Water Corporation. High-hazard sites, such as chemical manufacturing plants or commercial breweries, must install highly secure, testable Reduced Pressure Zone (RPZ) valves to prevent severe contamination.

For medium or low-hazard situations, like a standard residential property with an underground bore or a basic reticulation system, a simpler double check valve is usually sufficient. Our licensed team will conduct a thorough site assessment to determine your exact risk level and install the correct, legally compliant device.

No, not every registered plumber is legally allowed to install or commission testable backflow prevention devices in Western Australia. The installation and subsequent certification must be carried out by a specially endorsed backflow plumber who holds the specific qualifications required by the Water Corporation.

Attempting to use an uncertified contractor or attempting a DIY installation will immediately result in rejected compliance paperwork and potentially massive fines. Brett and the team hold all the necessary backflow endorsements, ensuring your new installation is completed safely and logged correctly with the authorities on the very first day.

The location of your backflow prevention device depends heavily on what it is designed to protect. For boundary protection, the valve is typically installed immediately after your property's main water meter, shielding the entire municipal supply from anything occurring on your site.

Alternatively, zone protection involves installing the valve directly at the specific source of the hazard, such as an industrial chemical vat or a commercial coffee machine. We carefully evaluate your property's layout to determine the most effective location, ensuring the device is easily accessible for mandatory annual testing.

It is completely normal to experience a very slight reduction in water pressure after a testable backflow device is installed on your main water line. These heavy-duty valves rely on powerful internal springs and check mechanisms to prevent reverse flow, which naturally creates a small amount of resistance as the water pushes through.

However, a professionally engineered installation will ensure this pressure drop is minimal and barely noticeable during your daily operations. We accurately calculate your property's peak flow requirements and precisely size the new pipework to ensure your showers, commercial kitchens, or reticulation systems still perform flawlessly.

You do not need to personally navigate the complex bureaucratic process or contact the Water Corporation directly. As fully endorsed backflow specialists, we manage all the mandatory compliance reporting and testing documentation on your behalf immediately following the installation.

We rigorously test the newly installed valve, record the diagnostic pressure readings, and submit the official commissioning certificate directly to the relevant Western Australian authorities. This seamless service provides you with immediate peace of mind, knowing your property is legally compliant and fully protected from the moment we leave.
