What is AS4032.3?
AS4032.3 is the Australian Standard for thermostatic mixing valves — specifically for healthcare premises. It sets out the requirements for the selection, installation, commissioning, maintenance, testing and documentation of TMVs in facilities where scalding prevention and Legionella risk management are critical.
In plain terms: if your aged care home, hospital, disability facility or community health centre has hot water systems with mixing valves — and almost all do — AS4032.3 tells you exactly what you need to do to manage them safely, and prove it to an auditor.
Who does AS4032.3 apply to?
AS4032.3 applies to any health or aged care facility in Australia where TMVs are installed as a means of scalding prevention. This includes:
- Residential aged care facilities
- Public and private hospitals
- Day surgery and procedure centres
- Disability residential facilities
- Community health and rehabilitation centres
- Mental health facilities
- Any other health premises with thermostatic mixing valves
If your facility is registered with the Aged Care Quality and Safety Commission (ACQSC) or accredited under the National Safety and Quality Health Service (NSQHS) Standards, TMV compliance documentation will be reviewed as part of your accreditation assessment.
What does AS4032.3 require?
The standard sets out obligations across five areas. Each one needs to be documented, scheduled and demonstrably maintained.
| Requirement Area | What It Means for Your Facility |
|---|---|
| Asset Documentation | Every TMV must be registered and documented — location, type, installation date, make and model. |
| Scheduled Maintenance | TMVs must be serviced at defined intervals. The standard specifies testing frequency based on valve type and facility risk profile. |
| Temperature Performance | Outlet temperatures must be measured and recorded at each service. Results must fall within the standard's specified ranges. |
| Audit Trail | A complete, chronological record of all services, tests and maintenance must be maintained and available for inspection. |
| Legionella Risk Management | TMV maintenance is a critical control measure in water system Legionella management plans — documentation is mandatory. |
How TracValv addresses every AS4032.3 requirement
TracValv is built from the ground up around the AS4032.3 standard. Every feature maps directly to a compliance obligation — no workarounds, no retrofitting, no compliance theatre.
Asset documentation
TracValv's digital asset register captures every required data point for every TMV — location, make, model, serial number, install date and valve type. Full valve history is stored permanently and is always searchable. Bulk import means migrating from a spreadsheet takes minutes.
Scheduled maintenance
Service intervals are set automatically on registration based on valve type. Tiered alerts at 30, 14 and 7 days before due ensure services are completed on time. Every completed service is recorded with timestamp and technician details — your audit trail builds itself.
Temperature performance
In-app temperature logging captures hot and cold outlet temperatures at the point of service. Results are stored against the valve record. Out-of-range results are flagged immediately — so issues are caught at service time, not at audit time.
Audit trail
Every action taken in TracValv — from valve registration through to service completion — is timestamped, attributed and permanently archived. Your audit trail is always complete and always current. One-click reports compile everything into a formatted PDF, ready for ACQSC or state health department review.
Legionella risk
Overdue valve alerts and portfolio-level compliance dashboards support active Legionella risk management. TracValv gives facility managers real-time visibility of any gap in their TMV maintenance programme — turning reactive risk into proactive control.
Why this matters now
The Royal Commission into Aged Care Quality and Safety has permanently elevated compliance expectations across the sector. State health departments and accreditation bodies are intensifying their focus on water safety and TMV documentation. The Aged Care Act 2024 has lifted the bar on documentation obligations for registered providers.
Compliance gaps identified in audits are increasing. The appetite for a documented, auditable, defensible system has never been higher — and the consequences of being caught short have never been more serious.
TracValv is the only dedicated, AS4032.3-aligned TMV asset management platform built for Australian health and aged care. Built around the standard. Hosted in Australia. Ready to use from day one.
