Backflow prevention device

Compliance you can hand straight to council or your auditor

Commercial properties in Sydney are required to have annual backflow device testing (to protect the public water supply), TMV (thermostatic mixing valve) testing in medical and aged care, grease trap compliance, and fire hose reel certification. We deliver the certificates the way Sydney Water, council and your insurer want them — issued same day, digital, searchable.

  • Annual backflow prevention device testing & registration
  • TMV testing & certification (healthcare/aged care)
  • Grease trap pump-outs & servicing
  • Fire hose reel & hydrant testing (AS 1851)

FAQs

Common questions about commercial plumbing

If you can’t see your question here, call us — we’re happy to talk it through.

Do you have commercial insurance and licences?
Yes — $20 million public liability, NSW plumbing and gas fitting licences, backflow accreditation and fire services accreditation. Certificates of Currency are sent on request for any job.
Can you work after hours?
For commercial and strata work, absolutely. Most cafes, restaurants and childcare clients prefer early-morning or evening installs. We’ll quote the time slot that suits your operation.
Do you offer account terms?
Yes, 14- and 30-day accounts are available for established commercial clients. New commercial jobs are typically pay-on-completion for the first two invoices, then account terms after.
Do you handle council and Sydney Water paperwork?
Yes — backflow registration, meter upgrades, tradewaste applications, grease-trap approvals and Sydney Water Section 73 work. We deal with council and utilities directly so you don’t have to chase reference numbers.
Can you be the single provider for plumbing, gas, drainage and fire?
That’s exactly how most strata and facility managers use us. One point of contact, one invoice stream, and one compliance calendar covering everything in the building.
We’re opening a new venue — can you do the fit-out?
Full hospitality and retail fit-outs are a big part of what we do. We’ll work to the builder’s program, coordinate with the shopfitter, and deliver all the certificates the handover needs.
