Backflow occurs when water flows in the wrong direction, allowing contaminants to enter Sydney’s clean water supply. To prevent this risk, Sydney Water requires many properties — especially commercial and multi-unit sites — to have approved backflow prevention devices installed. At Get Unblocked, our licensed plumbers supply and install valves that meet all Australian Standards. While we’re trusted for blocked drains, we also provide compliance plumbing, including backflow systems, testing, and annual certification.

Excellent service from Joe. We had a sewer blockage emergency on the weekend and they responded quickly and professionally. Joe carried out a CCTV inspection, clearly explained the issue. Luckily the pipes were in good condition and they managed to clear the blockage efficiently. Very honest, knowledgeable, and friendly team. Highly recommend for any drainage or sewer problems.Posted on Google![]()

Joe was great to deal with. He fixed a blockage in the two rear bathrooms at our place quickly and without any fuss. Super friendly, explained what was going on, and most importantly left everything clean when it was all sorted. Solid plumber and won’t hesitate to use these guys again.Posted on Google![]()

Joe supplied and installed a new electric hot water system at a great price — cheaper than the specialist hot water companies. He removed all the old unit and rubbish and tested everything before leaving. Highly recommend.Posted on Google![]()
