Test 3: H1 and H2 Combined Performance and Street Supply Test
Water was simultaneously drawn, at the flow rates below, from a single outlet of street spring
hydrants H1 and H2. The pressure was recorded at the outlet of H1 and H2 to determine the hydrant
performance. These pressures are used to determine if the hydrant meets the pressure requirements
of AS2419.1. The residual pressure was recorded from the outlet of street spring hydrant H3.

Test 3 Comments: This test was conducted in 10L/s increments due to H2 being in a driveway.

Hydrant Condition: H1, H2 and H3 were in good condition with a powder coat exterior.

General Notes:
• The test results are correct at the time of the tests
• Flow meters and pressure gauges are calibrated annually
• It is the responsibility of the recipient to determine the effect of changes in domestic/industrial usage, modifications to the
  main, differences in RL and extra hydraulic losses between the hydrant and tie in locations
• Flows are accurate to ±0.2L/s. Pressures are accurate to ±10kPa
