PRESSURE TESTING, LEAK REPAIRS, COMPLIANCE AUDITS & MAINTENANCE.

Certified strength and tightness testing of new, modified, and existing gas, fire water, and water pipelines across all pressure regimes (both under 200 kPa and >200 kPa Class I(B) systems), complete with calibrated gauge/chart recorder verification and NATA-traceable test documentation.

Experienced in water removal from gas piping and complete pipeline repair, including water ingress caused by burst water pipes jetting into gas lines, cross-connections, or flooding. We repair both the water and gas pipework, extract water from lines, meters, regulators, and appliances, and purge and recommission the gas system.

We specialise in commercial fire water services and the installation, maintenance, and mandatory annual testing of testable backflow devices, including Double Check Valves (DCVs) and high-hazard Reduced Pressure Zone Devices (RPZDs). We also provide expert mechanical repairs, fire hose reel change-outs, and landing valve replacements to ensure compliance with AS/NZS 3500.1, AS 2419.1, and AS 2441.

Thorough site-wide audits against AS/NZS 5601.1, AS 3814, AS 1375, AS/NZS 1596, AS 2896, AS/NZS 3500, AS 2419.1, AS 2441, and the National Construction Code (NCC). We deliver clear, prioritized engineering reports identifying non-conformances, corrosion risks, ventilation deficits, and signage/labeling gaps, paired with practical rectification scopes.

Scheduled servicing of Type A and Type B gas appliances, commercial hot water and pool heating plants, backflow and water supply systems, valve train leak testing, safety shut-off valve actuation checks, BMS flame-failure response testing, regulator overhaul, and combustion efficiency tuning.

Safe nitrogen purging, gas-free verification, and mechanical isolation of redundant plant, plus turnkey execution of audit rectification works, regulator upgrades, below-ground PE electrofusion and butt-welded extensions, and protective wrapping/coating remediation using Stopaq, Canusa, Denso, and Solartech.
