Hydrant – Sprinkler Flow Testing

Hydrant — Sprinkler Flow Testing is a routine requirement of Australian Standards (AS1851-2005) and ensure the performance of your Fire Protection System. Hydrant systems supply the water used by the Fire Brigade Service in the event of a fire. Sprinklers systems operate automatically to prevent the spread of fire. Hydrant and sprinkler systems are both hydraulically designed to deliver a specific volume of water at determined pressures. A building’s construction, height, area, and purpose determine the hydraulic system design criteria. The design criteria must be included in a building block plan and expressed as litres per second (l/s) and pressure (kilopascals-kPa). During flow testing, this information ensures the correct performance can be reached.

Hydrant Sprinkler Flow Testing
Hydrant — Sprinkler Flow Testing is a routine requirement.

A block plan indicates the location of critical components such as control/landing/isolation valves and pumps associated with the building. The Hydrant system block plan can be found at the Booster Valve Assembly, and the Sprinkler System block plan at the sprinkler control valve set. This information is critical and highly valued by the fire service. It is a mandatory requirement (AS1851-2005) to carry out annual flow tests of all Hydrant and sprinkler systems. Filing the Annual Fire Safety Statement(AFSS) to Council and Fire and Safety Authorities confirm the water supply has met the specific system design criteria. Torvac Solutions’ technicians have the expertise and experience to carry out all Hydrant — Sprinkler Flow Testing.

Hydrant Flow Testing

Hydrant Flow Testing is a routine requirement of Australian Standards and ensure your fire protection system performs when you need it to.

The minimum requirements for servicing of fire hydrants are specified in AS 1851 section 4, and this requires:

Torvac technicians will test the most hydraulically disadvantaged hydrant/s (we also will conduct additional flow tests to investigate various parts of the system as required).

We will also carry out the following;

Torvac Solutions will provide a flow test report, a defect rectification authority detailing any defects found as part of the service and a record of service report. Torvac will also provide advice and assistance on any defects identified and options for rectification.

Sprinkler Flow Testing

Automatic fire sprinkler systems prevent the spread of fire and are a requirement of some classes of buildings. Sprinkler Flow Testing is your guarantee that your Sprinkler System will perform as required. Each State in Australia has specific legislation, together with the Building Code of Australia, stating the requirement for the installation and maintenance of these systems. Maintenance activities are defined by Australian Standard AS1851, the Standard sets out the frequency of maintenance and activities for an automatic fire sprinkler system and its components. A flow test, also known as a water supply proving test, is a functional test & measurement of the water supply for an automatic fire sprinkler system. Torvac Solutions technicians use the Ambit SF300 sprinkler Flow Tester, to ensure there is an adequate supply of water (flow and pressure) to satisfy the approved design & demand of the sprinkler system.

The performance criteria (baseline data) that forms the approved design of the automatic fire sprinkler system is recorded in as part of the required commissioning documentation and “Sprinkler Block Plan”. The block plan records details including the type, location & features of each water supply, the type, capacity, and location of each pump-set, the type and the size and location of each sprinkler installation.

The block plan will also record the height of the most disadvantaged sprinkler head, along with other related information. The flow test measures the pressure and flow of each water supply, including pumped water supplies. The pressure and flow rate is measured using calibrated gauges, with the results recorded for later analysis.

Once the test is completed, the results are entered into a report that includes the required pressure & flow criteria of the approved design for the fire automatic sprinkler system; details of each water supply, pumps, and tanks.
