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.
Healthcare facilities — GP clinics, dental practices, day surgery, specialist offices, imaging clinics. TMV + backflow + gas, all bundled.
Aged care providers — nursing homes, assisted living, retirement villages. Annual TMV at every shared tap and shower (resident safety), backflow on incoming water main, CO testing on shared gas hot water plants. Reports formatted for clinical-governance audit.
Childcare centres — annual TMV on every basin and shower used by children, backflow on any food-prep area connection, gas compliance on kitchen appliances. Department-of-Education-compatible reporting format.
Body corporates — annual backflow on the building's main RPZD, TMV testing in common-area amenities, CO testing on shared gas hot water plant rooms. Strata-manager-direct invoicing.
Commercial premises — food retail tenancies, restaurants, cafés, factories, warehouses. Backflow testing for food/chemical operations, gas compliance for kitchens.
Backflow gauges and TMV thermometers calibrated annually with traceable certificates. Calibration records available on request — auditors and water authority reviewers ask for them periodically.
Backflow reports lodged direct with Yarra Valley Water in their standard format. TMV reports in the per-valve format aged-care and Department of Health inspectors recognise. Gas Compliance Certificates BPC-issued and valid for all Victorian audits.
BPC #103414 with backflow prevention endorsement. Type A gasfitter through Energy Safe Victoria. Master Plumbers Australia member. Backflow Prevention Association of Australia member. Public liability insurance certificate available on request — frequently asked for by facility managers and body corporate committees.
Per-device fixed price, listed on the quote. Multi-device discounts on properties with 5+ test points. Body corporate / multi-tenancy reductions for shared infrastructure. Quote covers the year ahead so the cost is known up-front.
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.
Backflow reports lodge electronically with the water authority within 5 business days of the test. You don't chase paperwork; we send the confirmation receipt once YVW accepts the lodgement.
Annual reminder sent to your nominated facility or strata manager one month before next year's test is due. Removes the risk of a missed test deadline that would put the property out of compliance.
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 had a YVW compliance notice or a non-conformance finding, send the notice through. We'll close out the non-conformance in the first visit and bring the property current.
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.
Same-week response on most non-conformance fixes. If a device needs replacement, we hold common RPZD and DCV sizes; non-standard sizes are sourced and fitted within 5-7 business days.
Yes, by arrangement. Common for retail tenancies and healthcare facilities where the system can't be isolated during operating hours. We schedule weekend and evening testing where the property needs it.
Fixed-price per device, listed on the quote. Multi-device discounts on properties with 5+ test points. Body corporate / multi-tenancy reductions for shared infrastructure. The quote covers the year ahead — no surprises mid-cycle.
Yes. We've serviced shopping strips, apartment complexes, multi-building aged-care facilities and school campuses. Reporting is structured per tenancy/building so each compliance team sees only the parts relevant to them.
Filed with Yarra Valley Water or the relevant AHJ within 5 business days of the test. PDF copy emailed to your facility/strata manager the same day where requested.
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.
