Backflow Prevention & TMV in Sydney.

Yes — Sydney Water requires testable backflow prevention devices to be tested every 12 months by an accredited plumber, with results lodged. Fines apply for lapsed devices, and we make sure you never lapse.

A thermostatic mixing valve delivers water at a safe, stable temperature — mandatory in aged care, childcare, schools and healthcare, and best practice in commercial amenities. They must be serviced every 12 months.

We tell you on the spot, quote the repair or replacement, and in most cases rebuild and retest the device in the same visit so your compliance never lapses.

Yes — we consolidate all your devices into one register, align due dates where possible, and invoice once. Property managers typically save hours of admin a year.

Any connection where contaminated water could be drawn back into the drinking supply needs protection — think irrigation systems, fire hose reels, commercial kitchens, workshops with chemical use, or medical and dental suites. Sydney Water rates each property's hazard level, and the rating dictates the device type. Unsure where you stand? We'll audit the site and confirm exactly what's required.

Briefly, yes — testing a backflow device means isolating it for around 15 to 30 minutes per device, and a TMV service interrupts the outlets that valve feeds. On occupied sites we schedule around your quiet periods, stagger devices so the whole building is never off at once, and give tenants notice beforehand. Most occupants never notice we were there.
