Backflow Device Repair in Sydney

Backflow device repair in Sydney: if your device failed its annual test, it usually needs a repair kit, not a new unit. Until it passes, the property is non-compliant.

The finished result of backflow prevention.

The short answer

Most failed backflow devices need a repair, not a new unit. We replace the worn seals or check valve, retest the device and lodge the result, usually in one visit.

What happens when you get in touch

  1. Step 1: Call or book online

    Tell us what is happening. We ask the right questions and book a time that suits you.

  2. Step 2: We find the cause

    A licensed plumber diagnoses it properly, with a drain camera, leak detection or a pressure test where it helps.

  3. Step 3: A fixed price, agreed first

    You agree the price before any work starts. We quote the job, not the hour, so there are no surprise charges.

  4. Step 4: Done right, guaranteed

    We finish the job, clean up, and back our workmanship with a lifetime labour guarantee.

  5. Step 5: You know the price first

    The figure for the whole job, in writing, before anyone starts. That figure is what turns up on the invoice.

Questions and answers

Repair, in nearly every case, because what fails is seals and check valve internals rather than the brass body. A replacement price only goes to you when the body has corroded through or nobody makes parts for that model any more.
