If your building has annual compliance testing on its plumbing system, Prime Plumbing & Gasfitting handles all four together: backflow prevention, thermostatic mixing valves (TMV), gas compliance and carbon monoxide testing. One contractor, one quote, one annual visit, reports lodged with Yarra Valley Water and any Authority Having Jurisdiction direct.
Built for healthcare facilities, aged-care providers, childcare centres, body corporates and commercial premises across Melbourne's east and south-east.
Quick answer: If your building needs annual backflow testing, TMV testing or gas compliance checks, Prime Plumbing & Gasfitting runs the schedule for you: testing by a licensed plumber, results lodged where required, and records you can hand straight to your auditor or insurer. BPC licence #103414. One contact, written fixed prices, and agreed next-test dates.Most commercial properties end up with separate trades for backflow, TMV, gas compliance, and carbon monoxide testing. Booking, paying and chasing four separate annual reports across four contractors is expensive admin. Combining them into a single annual visit through one contractor cuts admin time, downtime and total cost. One visit instead of four. One quote, fixed price. One contact for compliance follow-up. One Compliance Certificate file to keep with your property records. Ask for current licence, endorsement, accreditation and insurance details relevant to the quoted work.

Yarra Valley Water for backflow. AS/NZS-compliant per-valve sheets for TMV. CO readings per appliance. Gas compliance summary plus Compliance Certificate where any work has been performed.
Each backflow device and each TMV gets a dated, signed test tag. Auditors check tags, current-date tag means current-year compliance. Tag includes Prime's tester licence reference and the next-due date.
Confirm the relevant water authority, lodgement deadline and reporting responsibilities when booking. Ask for a copy of the test report and any required lodgement receipt for the property records.
Record the next test due date and agree who will arrange the next visit. Any reminder service and the nominated contact should be confirmed when the work is booked.
For new clients taking over an existing compliance contract, the four items below let the first visit run efficiently.
If you have prior backflow and TMV test reports, send them through with the quote request. We use last year's results as a baseline and compare valve-by-valve to flag drift early.
Device count, location, type (RPZD / DCV / single check / TMV / CO point) and any known issues. The list lets us batch the visit efficiently and ensures nothing is missed during the test cycle.
If the property has a water-authority compliance notice or an audit finding, send it with the enquiry. The required assessment, repair scope, parts and completion timing can then be confirmed.
Plant rooms, backflow pits and shared service cupboards sometimes need keyed access. Confirm the site contact, key handling, and any contractor-induction requirements before the first visit so the test can run uninterrupted.
Both annually, under AS/NZS standards (4032.3 for TMV, 2845.3 for backflow). Some high-risk premises require six-monthly. We'll confirm your specific cycle from the device classifications during the first visit.
Yes. Send through last year's test report (or the Yarra Valley Water notice listing your devices) and we'll quote a like-for-like replacement contract.
Send the compliance notice and any previous test report with the enquiry. Response time and repair completion depend on site access, the fault and parts availability; confirm the proposed timing before booking.
Discuss any evening or weekend access requirement when requesting a quote. Attendance outside normal hours depends on availability and needs to be agreed before booking.
The written quote should list the devices, tests, reporting and any agreed repair scope. Confirm the contract period, any discounts and how additional work will be quoted before accepting.
Send each property's address, site contacts, device list and existing reports so the scope and reporting arrangements for multiple buildings or tenancies can be agreed.
Confirm the required reporting and lodgement deadlines when requesting the quote. Report format, recipient and delivery timing should be agreed before the visit.
Yes, see our TMV testing page. Combined visits cost less than booking each test separately, but standalone TMV testing is available for facilities that only have TMVs and no other compliance scope.
Call 0475 407 670 or send your property address through the form below. We'll quote a fixed-price annual contract covering all four compliance tests, backflow, TMV, gas, CO, and lodge all paperwork with Yarra Valley Water and the relevant authorities direct.
