Comprehensive Backflow Testing & Maintenance

Backflow occurs when the normal outward flow of water reverses direction, pulling contaminated wastewater back into the clean public drinking supply. This dangerous reversal is usually triggered by a sudden, massive drop in pressure within the municipal water mains, often caused by a burst street pipe or heavy usage from fire hydrants.

When this pressure drops, it creates a vacuum effect that actively siphons stagnant, chemical-laced water from your property's irrigation, industrial vats, or grease traps backward into the scheme water. This poses a massive biological and chemical hazard, potentially causing severe illness across the entire surrounding community if the contaminated water is ingested.

Yes, the installation of a backflow prevention device is a strict legal requirement under Western Australian plumbing regulations for any property deemed a contamination risk. The Water Corporation assesses the specific hazard rating of your premises to determine exactly which type of valve must be installed at your property boundary or individual fixtures.

High-hazard properties, such as chemical manufacturing plants, hospitals, and mechanical workshops, absolutely must have heavy-duty, testable devices installed by a licensed professional. Even standard residential homes with alternative water supplies, underground bore pumps, or complex reticulation systems connected to the mains are legally required to have appropriate backflow protection in place.

To ensure they function perfectly during an emergency pressure drop, all testable backflow prevention devices must undergo a rigorous inspection every twelve months. This annual testing is a strict legal mandate enforced by the Water Corporation to protect the integrity of the state's drinking water infrastructure.

If you fail to have your valves tested and certified by the anniversary date, you risk receiving massive non-compliance fines and having your property's water supply completely disconnected. Brett and the team can manage this entire process for you, sending annual reminders and submitting the necessary paperwork to keep you fully compliant.

During a standard backflow test, our specially endorsed plumbers connect highly calibrated pressure gauges to the specific testing ports on your device. We carefully measure the differential pressure across the internal check valves to ensure they are sealing completely and preventing any reverse flow of water.

We also physically inspect the valve body for any signs of external corrosion, leaking seals, or mechanical degradation that might compromise its performance. Once the device passes these rigorous checks, we immediately submit the official compliance certificate to the Water Corporation, updating your property's legal safety records for another year.

Absolutely. If your backflow prevention device fails the pressure test, it simply means the internal rubber seals or spring mechanisms have worn out and are no longer holding the water back. Instead of immediately quoting you for a highly expensive, total unit replacement, we will always attempt a comprehensive repair first.

Our service vehicles carry a massive range of premium replacement parts and internal repair kits for all major backflow valve brands. We can quickly disassemble the unit, replace the degraded components, thoroughly clean the internal casing, and successfully re-test the device to instantly restore your property's legal compliance.
