 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.

 Trustindex verifies that the original source of the review is Google. Always have scrutiny with any trade that you call in an emergency. Absolute gentleman. 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 a backflow compliance certificate?

A backflow compliance certificate is an official legal document required by the Water Corporation to prove your prevention device is functioning correctly. This mandatory paperwork confirms that a specially endorsed plumber has rigorously tested the internal check valves to ensure contaminated water cannot siphon back into the public drinking supply.

Without this vital certification, the authorities have no proof that your property's high-hazard or medium-hazard plumbing infrastructure is safe. If you fail to produce a valid certificate by your annual due date, you risk severe financial penalties and the immediate disconnection of your scheme water supply.

How often do I need to renew my compliance certification?

In Western Australia, all testable backflow prevention devices must be professionally inspected and certified every twelve months without exception. This annual schedule is strictly enforced by the Water Corporation to guarantee the ongoing integrity of the state's municipal water infrastructure.

Because the internal rubber seals and mechanical springs degrade over time, a valve that passed last year could easily fail today. We help you stay ahead of these strict deadlines by providing automated annual reminders, ensuring your property is always certified well before the official expiry date.

Who is legally allowed to issue a backflow certificate?

Not every licensed plumber is legally authorised to test valves or issue backflow compliance certificates in Western Australia. The process must be completed by a specialist backflow plumber who has undergone additional, rigorous training and holds a specific endorsement from the relevant authorities.

Attempting to use an uncertified contractor will result in your testing paperwork being immediately rejected by the Water Corporation. Brett and the team possess all the mandatory backflow endorsements, ensuring your certification is legally binding and accepted by the authorities on the very first submission.

What happens if my device fails the certification test?

If your backflow valve fails the mandatory pressure test, we cannot legally issue a compliance certificate until the underlying fault is fully resolved. A failed test usually indicates that the internal check valves have worn out, allowing water to slowly leak backward through the device.

Fortunately, a failed test rarely means you need to pay for a highly expensive, complete unit replacement. Our service vehicles are fully stocked with premium replacement parts, allowing us to rebuild the internal mechanisms on the spot and instantly re-test the device to secure your certification.

Do I have to send the certificate to the Water Corporation myself?

Navigating the complex submission process and dealing with government bureaucracy is incredibly frustrating for busy property owners and facility managers. When you hire our endorsed team, you do not have to worry about manually lodging any testing paperwork with the authorities.

Once your backflow device passes our rigorous testing, we immediately submit the official compliance documentation directly to the Water Corporation on your behalf. We also provide you with a digital copy for your own legal records, giving you total peace of mind that your property is fully protected.
