Sydney Backflow Prevention are experienced in repairing all different makes and models of backflow prevention devices, including Ames, Apollo, AVG, Caleffi, Conbraco, Febco, Flomatic, Tyco, Valcheq, valvtec, Watts and Wilkins Zurn. This service is very popular with other plumbers who may not be familiar with the best repair procedures for certain valves. We can save you a lot of time and money with our expertise.


As well as inspecting your containment backflow device, Sydney Backflow Prevention can also test the other zone and individual backflow devices at your property. We will provide a report on these devices so you can be sure they comply with The Plumbing Code of Australia and Australian/New Zealand Standard 3500:1.

Thermostatic Mixing Valve

Servicing (TMV)

Sydney Backflow Prevention service and repair all major brands of Thermostatic Mixing Valves (TMV), including AquablendRada, Hansa, AVGZip HorneTomsonMora and Stabitherm. They are primarily used in medical centres, childcare and aged care facilities to protect against scalding injuries, thermal shock and the build up of Legionella bacteria. TMV's need to be tested annually to ensure they comply with relevant regulatory requirements. Contact us to arrange the servicing and maintenance of your TMV's. 


A growing part of Sydney Backflow Prevention's business is providing backflow prevention testing and repair services to other plumbing businesses. If you are not backflow accredited or do not have enough backflow customers to justify the cost of buying and calibrating a test gauge every year, we can provide very competitive prices to do your backflow testing and repairs.
