Plumbing & Pipeline Solutions (PPS) were engaged by a major government facility to conduct an urgent audit after concerns were raised about the high temperature of water from a public basin tap.
PPS was selected for the job due to our strong track record in conducting compliance audits and our pre-approval for work in high-security, sensitive environments including government buildings, law courts, hospitals, schools, and police stations.
Our investigation revealed that hot water temperatures at several outlet points were exceeding 60°C — well above the allowable limit under Australian regulations.
To address this, we recommended the installation of Thermostatic Mixing Valves (TMVs) to regulate and maintain safe water temperatures throughout the building.
Given the safety risk, the client approved immediate action.
PPS began by installing isolation valves on the hot water branch lines after hours to prevent disruption to building occupants. This allowed our team to access and modify specific pipework sections during the day.
Over the course of just one week, we installed more than 20 TMVs throughout the facility, setting each valve to 45°C — the recommended safe temperature per Australian Standard AS 4032.1.
By strategically scheduling works and minimising downtime, we delivered an efficient, cost-effective result with minimal disruption to daily operations.
With the TMVs now in place, the risk of scalding has been eliminated, ensuring safer water delivery for all users. Each valve was registered and incorporated into a regular maintenance program for ongoing compliance and performance.
This project highlights PPS’s ability to deliver compliant, high-quality plumbing outcomes in operational government environments — on time, with care, and without unnecessary intrusion.
