Testimonials

John S

Owner. Cafe in Malvern

I was a bit shocked to learn that my water could have been cut off at any time because I hadn’t been getting my backflow prevention equipment tested. Luckily Paddy happened to be eating at the café and asked me how often I got my backflow equipment tested and when I said “never” he quickly explained what needed to happen. And within 24 hours the equipment had been tested and I now have the peace of mind that my water won’t be turned off!

Katie W

Owner. Restaurant in Ringwood

I received a letter from Yarra Valley Water telling me it was law in Australia for our restaurant to have backflow prevention equipment and to have it tested regularly. I definitely panicked a little as I had never heard of Backflow Prevention. However Mark and the team from Backflow Prevent were fantastic and installed my new backflow prevention equipment within a couple of days and I have a testing schedule in place which is actually quite cheap. And Backflow Prevent even notified Yarra Valley Water so I didn’t have to worry about then sending me another scary letter! I would highly recommend to any restaurant to give Backflow Prevent a call.
