Backflow devices and thermostatic mixing valves protect drinking water and people. Both need regular testing to stay compliant, and we make that simple for property owners, strata managers and businesses across the Central Coast.
Backflow prevention
A backflow prevention device stops contaminated water flowing back into the mains supply. Commercial properties, strata complexes, and properties with fire services, irrigation or rainwater tanks often need one. We install, test, repair and register devices, and lodge results with the water authority.

Thermostatic mixing valves (TMV)
TMVs blend hot and cold water to a safe temperature to prevent scalding. They are required in aged care, childcare, healthcare and many commercial settings, and need regular servicing to keep working correctly. We service, test and replace TMVs and keep records for your compliance reporting.

Common questions
How often does a backflow device need testing?
Testable backflow devices must be tested at least once a year by a licensed and accredited plumber, with results lodged with the water authority.
Does my property need a backflow device?
Commercial, industrial and strata properties and homes with fire services, irrigation or rainwater tank connections often do. We can assess your site.
How often should TMVs be serviced?
Requirements depend on the setting. In healthcare and aged care, TMVs are typically tested at least annually. We will set up a schedule that keeps you compliant.
