In Western Australia it is law to have your backflow device tested annually. The Western Australian Water Corporation will send you a letter notifying you that your device is due to be tested. It is your responsibility to enlist the services of an accredited backflow tester, to carry out the test. A quick phone call or online enquiry to Perth Backflow Specialists and we will have your appointment booked and your backflow prevention system tested in no time. We will also save you the hassle of completing paperwork by, submitting the test reports through the Water Corporation’s online system. We will also send you a reminder when your backflow device is due for it’s next service.
