The required equipment needed for this test is:
The flow testing procedure should be conducted, as follows:
- Position one personnel at the test hydrant, and one at the flow hydrant.
- Flow hydrant should be located downstream from the test hydrant, or next in line in direction of flow.
- Attach gauge to test hydrant.
- Open hydrant; record static pressure reading.
- Record outlet coefficient size of flow hydrant.
- Attach pitot gauge to flow hydrant.
- Open hydrant; record pitot/flow gauge reading (flow for 2 minutes).
- At test hydrant, record residual pressure reading (should not be less than 20% of flow)
- Shut down flow hydrant.
- Shut down test hydrant.
- Disassemble gauges from hydrant.
- Hydrant test is now complete.
