Backflow Prevention

The purpose of a backflow prevention device is to stop water on the down stream side of the valve making its way into the drinking water supply.

Backflow Prevention

Backflow valves are found in all sorts of situations deemed as a high risk of contamination. Commonly found under fire hose reels, at the boundary of a property and in places like bin rooms and car washdown areas, ensuring you can trust the water coming out of your tap.

There are many different manufacturers, with many more valves in Australia, we carry parts for each valve prior to attending site. In almost all situations it is more economical to rebuild a valve than to replace it, saving you money and potential down time. We routinely service and carry parts for (but not limited to) Tyco, Valve Cheque, Febco, Watts and Conbraco, in Double Check (DCV), Reduced pressure zone device (RPZD) and Single Check (SCV) in all sizes, from 15mm to 100mm and more.

Some FNQ councils have implemented a policy to bring all commercial premises into line with the Australian standards.  This requires all high risk premises protected with backflow prevention devices and all devices registered with council and tested yearly.  At Tropical Backflow and TMV, we are able to conduct a site audit, if desired, and register and test all devices on site.  We can also clarify the requirements of the standards, and what is expected in each situation.  This is national legislation, enforced by local councils, as each council is responsible for the potable water they supply to their constituents.  Once the site is up to standard and the devices tested, and registered you will need them tested each year to ensure they are working properly.

There is no minimum or maximum number of valves for us, If you have 1 or 100 that you need tested, serviced, installed or replaced give us a call on 0419 349 697 or send us an email via
