Test 1: H1 Performance and Street Supply Test
Water was drawn, at the flow rates below, from both outlets of street spring hydrant, H1. The pressure
was recorded at the outlet of H1 to determine the hydrant performance. This pressure 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 H2.
