Aged Care Plumbing Compliance Checklist — Victoria 2026
Aged Care Plumbing Compliance Checklist — Victoria 2026 — a Prime Plumbing & Gasfitting plain-English guide to aged care plumbing compliance for Melbourne aged-care operators and facility managers. Below we cover what works, what doesn't, and when to call a licensed plumber.
Quick answer: Victorian aged-care facilities need four annual plumbing compliance tests, each under a different Australian standard: TMV testing on every resident-accessible hot-water outlet (AS/NZS 4032.3); backflow testing on the property's main and any kitchen/medical branch (AS 2845.3); gas compliance on the cooking, hot-water and any clinical-use gas equipment; and carbon monoxide testing where gas appliances serve common or sleeping areas. All four are checkable at Aged Care Quality and Safety Commission audit. Most facilities batch these onto a single annual compliance visit through one contractor holding all the relevant endorsements — easier scheduling, one paperwork bundle, one point of contact when something fails the test.
Why Victorian aged care has the highest plumbing compliance load
Aged-care premises combine the highest risk factors for plumbing-related harm:
- Residents with reduced thermal sensation can't tell scalding water in time → mandatory TMV protection
- Communal hot water systems mean a single device failure affects many residents
- Shared gas appliances in laundry, kitchen, hot water plant rooms → CO and gas compliance risk
- Backflow connections through medical bath/spa equipment, kitchen prep, irrigation → cross-contamination risk
- Audited regularly by the Aged Care Quality and Safety Commission — compliance failures are reportable to the regulator
This is why aged care has the most demanding annual plumbing schedule of any Australian facility type.
Where the regulator looks first at audit
Aged Care Quality and Safety Commission auditors typically open the plumbing folder for: (1) per-outlet TMV reports with current-year date; (2) backflow lodgement receipt from your water authority; (3) BPC Compliance Certificate for any install or replacement in the past 12 months; (4) legionella sampling results from a NATA lab. Missing any one of these is a finding. Our aged care plumbing contract delivers all four in one PDF per facility per year.
The 2026 annual plumbing compliance checklist
1. TMV testing — AS/NZS 4032.3
Who tests: licensed plumber with TMV testing endorsement Where: every TMV on a resident-accessible hot-water outlet — basin, shower, bath, wash trough Test target: mixed-water outlet stays at 38°C ±2°C, cold-failsafe trips within 5 seconds, hot-failsafe trips cleanly Documentation: per-valve test tag + site-level test report sheet Frequency: annual (some intensive-nursing settings 6-monthly)
The audit question: "Show me the current TMV test tag on the bathroom you just walked us through, and the matching entry in the site asset register."
2. Backflow testing — AS 2845.3
Who tests: licensed plumber with Backflow Prevention Endorsement Where: RPZD or DCV on the property's main water inlet, plus any high-risk branch (commercial kitchen, medical bath, irrigation) Test target: check valves seat under reverse pressure, pressure-relief vent operates within range, no internal corrosion Documentation: test report lodged with Yarra Valley Water (or relevant authority); copy on site Frequency: annual on medium and high hazard devices
The audit question: "Show me last year's backflow test certificate from Yarra Valley Water and confirm the date is within 12 months."
3. Gas appliance compliance
Who tests: licensed plumber with Type A gasfitter endorsement (Energy Safe Victoria) Where: every commercial-rated gas appliance — kitchen cooktops, ovens, hot water plant rooms, laundry dryers Test target: gas-tight connections, correct ventilation, isolation valves operational, Compliance Certificate on file for any work performed Documentation: Compliance Certificate from any new work or major service; periodic service report for ongoing equipment Frequency: annual for commercial appliances; on service for residential-style appliances
The audit question: "Show me the most recent Compliance Certificate for the kitchen cooktop bank and the laundry dryer."
4. Carbon monoxide testing
Who tests: licensed plumber/gasfitter with CO testing capability Where: any flued or unflued gas appliance serving common areas, sleeping areas, or areas of resident assembly Test target: CO emission within safe range from each appliance under normal operation; flue draft testing where applicable Documentation: CO test report with reading per appliance and pass/fail Frequency: annual, often combined with the gas compliance visit
The audit question: "Show me the CO test results for the gas hot-water plant and any space heaters."
Bonus items often missed at audit
- Legionella prevention on the hot water system — separate AS/NZS 3500.4 hot-water temperature management (60°C at storage, with TMV protection downstream). Auditors check the storage temperature is being monitored.
- Tempering valves on the secondary hot-water circulation loop — if the building has a circulating hot-water system, intermediate tempering valves may be needed in addition to point-of-use TMVs
- Kitchen grease trap maintenance records — not a TMV/backflow issue but plumber-issued, and audit-relevant
- Trade waste agreement compliance — if the facility discharges anything other than domestic sewage, the trade-waste agreement with the water authority needs annual review
Beyond the four basics — what gets missed in most facilities
Auditors will also check: warm-water storage temperature logs (60°C minimum per AS/NZS 3500.4 to control Legionella), tempering valve records on circulating hot-water systems, grease trap maintenance records for the kitchen, and any trade waste agreement compliance. None of these are part of a standard "TMV + backflow" annual visit unless explicitly contracted. Our aged care contract scopes the full list at the first walk-through.
Common audit findings (the issues to avoid)
From facilities we've serviced and audit reports shared with us:
- TMV test tags expired — last test was 13 months ago, not 12. Caught in 100% of audits where it happens.
- No backflow certificate on file — Yarra Valley Water has it but the facility records lost the copy. Easy fix: ask the contractor for a fresh copy.
- Compliance Certificate missing for the renovation work — work was done, but the Certificate wasn't lodged with facility records. Plumber can re-issue.
- Gas appliance modifications not on the asset register — a new cooktop was installed but the asset register still shows the previous model.
- CO test ignored on "non-shared" appliances — many facilities don't test CO on the laundry dryer because they think it's not in a sleeping area. If the dryer is gas and the laundry shares walls/vents with resident rooms, it counts.
The most common findings — and the fix for each
Expired test tags: book the annual visit 4 weeks before the existing tag expires, never after. Lost backflow certificates: request a copy from the water authority + the contractor — both keep records. Missing Compliance Certificate: the licensed plumber who did the work can re-issue from records. Outdated asset register: walk the building with the new contractor and rebuild from observed appliances. CO not tested on the laundry dryer: contract scope should include EVERY gas appliance regardless of zone. Our aged care plumbing contract covers the full asset register.
Combining the four tests into one visit
The four tests all need different test equipment and different documentation, but they don't all need different trades. One plumber holding all four endorsements (TMV testing, Backflow Prevention, Type A gasfitter, CO testing capability) can do all four on a single visit.
A typical combined annual visit for a 40-resident aged care facility:
- Half day on site — TMV tests on ~30-40 outlets, backflow test on the main + any branch devices, gas compliance walk of the kitchen + plant rooms + laundry, CO readings on each gas appliance
- Paperwork bundle delivered next business day — TMV report, backflow certificate (lodged with YVW), gas compliance update, CO test report
- Asset register updates so your facility's records are current
- Calendar reminder for next year's visit a month before due
This is exactly what Prime offers through the commercial plumbing compliance service.
Why combining the four tests saves more than money
Beyond the cost saving, combining the tests means one set of paperwork, one site contact, one access window, one consolidated report stored against the facility (not three different PDFs in three different folders). Audit prep becomes "open the plumbing folder" instead of "track down which contractor has which document". For a 40-resident RACF, a single half-day visit covers it all — see our aged care plumbing service.

When to Call a Licensed Plumber
Some plumbing problems are DIY-friendly; others need a licensed professional under Victorian law.
Anything involving gas, sewer drainage, hot water units, backflow prevention, or work behind tiled walls must be handled by a licensed plumber or gasfitter.
FAQs
Pull the previous facility records (TMV reports, last YVW backflow certificate, gas Compliance Certificates) and we can audit them against the standards in one site walk. A 1-hour gap-analysis visit identifies what's overdue.
Yes, as long as they hold the relevant endorsements. The TMV test tags and backflow certificates are device-based, not plumber-based — any qualified tester can pick up the next cycle.
The strict requirement is for resident-accessible outlets. Staff bathrooms aren't normally classified as vulnerable. But if your facility's policy is to standardise across all bathrooms, that's fine — annual TMV testing then covers them too.
We recommend permanent — TMVs are clinical-risk equipment and historical records may be relevant in an incident investigation. At minimum, retain the last seven years of test reports.
Yes — common for multi-site aged-care providers. We've serviced 3- and 5-site portfolios with the same combined compliance contract, run sequentially over a couple of weeks each year.
Before You Book
A quick checklist to share with your plumber when you book:
- When did the issue start?
- Is it isolated to one fixture or multiple areas?
- Are there any visible leaks, smells or unusual sounds?
- Have you turned off the relevant isolation valve?
If you're unsure, Prime Plumbing & Gasfitting can inspect the issue and explain the options before any work starts. Call 0475 407 670 or request a quote online.
