Essential Protection for the Community Water Supply

Whether you are managing a commercial industrial site or simply have a high-hazard reticulation system at home, preventing reverse water flow is critical. Without a functioning backflow prevention device, a sudden drop in municipal water pressure can siphon stagnant, chemical-laced water directly back into the clean drinking supply.

Mindarie Plumbing & Gas are fully certified to test, repair, and certify all types of backflow valves. We manage your testing schedule, submit all mandatory compliance paperwork directly to the Water Corporation, and ensure your property never faces heavy non-compliance fines.

 Trustindex verifies that the original source of the review is Google. As a reticulation contractor, we are always looking for reliable plumbers to work with.

We had a client in Burns Beach who noticed water leaking down their driveway while they were overseas on holiday. After seeing it on their CCTV, it became an urgent priority to have it fixed as soon as possible.

We were initially called out, as it was assumed to be an issue with the reticulation system. However, upon inspection, we quickly identified a leak in the copper pipe coming off the water meter.

We contacted Brett from Mindarie Plumbing and Gas and sent through some photos. Brett was able to provide a prompt estimate and arrange a time to attend the property in Burns Beach.

He quickly repaired the leaking copper pipe near the water meter, and upon completion, sent through photos, giving us peace of mind that the issue had been resolved.

Outstanding service from a reliable local plumber. We highly recommend Brett and the team at Mindarie Plumbing and Gas for any plumbing work in Burns Beach and surrounding areas.

Charged us reasonably the whole way through. Didn’t ask for a review which means all of his reviews are organic. Probably the first review I’ve gone out of my way to make which speaks volumes about Brett.

Frequently Asked Questions

What is backflow, and why is it dangerous?

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.

Do I legally need a backflow prevention device?

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.

How often does my backflow valve need to be tested?

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.

What happens during an annual backflow test?

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.

Can you repair a backflow device if it fails the test?

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.
