Hydrostatic testing proves your hydrant system can hold pressure. Booster flow testing proves it can deliver water at the required flow and pressure. One tests pipework integrity. The other tests hydraulic performance under simulated firefighting conditions. Passing one does not guarantee passing the other.

During five-yearly hydrant servicing, hydrostatic testing checks the pipework's ability to withstand pressure, while booster flow testing verifies water delivery under operational demand, helping identify restrictions, obstructions, and pressure losses between the booster arrangement, fire pump bypass, and remote hydrant outlets.

Unlike contractors limited to hydrostatic testing, AFT provides both hydrostatic pressure testing and specialised booster flow testing, assessing system integrity and hydraulic performance against applicable Australian Standards and design requirements.

A system that holds pressure may still fail to deliver water. AFT tests both, because firefighting performance depends on more than pipework integrity.

Booster Flow Testing

Simulates Department of Fire and Emergency Services (DFES) firefighting operations under the required design flows and pressures, verifying hydraulic performance and identifying potential obstructions between the booster assembly, fire pump bypass, and most remote hydrant valve.

5 Yearly Hydrant Service and Hydrostatic Testing

The full five yearly hydrant service including hydrostatic pressure testing, performed together with the booster flow test so the system is proven for both integrity and performance in the same programme.

Sprinkler and Drencher Systems

Testing, repair and rectification across sprinkler and drencher systems, including wall wetting and facade protection systems in high rise buildings, and pre-action systems in environments where an unplanned discharge carries its own consequences.

Fire Pump Sets

Testing, servicing and repair of electric and diesel fire pump sets, including performance verification against the design duty rather than confirmation that the pump starts.

Hydrants, Boosters, and Hose Reels

Routine servicing, repair and replacement across hydrant valves, booster assemblies and hose reels, including accessibility and signage at the booster, which is what the brigade relies on when they arrive.

Hydraulic Performance and Defect Rectification

Diagnosis and rectification where flow or pressure falls short of what the system was designed to deliver, including obstruction, valve and pipework issues that a pressure test alone will not surface.

Upgrades and Capacity Works

Wet system upgrades where a building’s use, layout or storage arrangement has changed enough that the installed system no longer matches what it is protecting.
