The shutoff head is equal to the static pressure head at hydrant 1.
Water flow test report.
In order to use the flow test results in a water model you must create a 3 point pump curve.
The design flow is the total flow from the test and the design head is equal to the residual pressure at hydrant 1.
A water flow test also known as a hydrant flow test is a way to measure the water supply available at a building site usually for the purposes of installing a water based fire protection system.
An alternative approach is to ask your county health department.
4 2 a typical town main can be tested at a single hydrant using a suitable flow and pressure test instrument.
4 3 larger mains of higher capacity will require the simultaneous testing of several hydrants.
You will receive a report that includes the static and residual pressure of the main and the flow rate at each hydrant.

4 1 the flow test procedure is carried out by measuring the flow of water available from the distribution system at the rating pressure.
During the course of the test the water flow should be monitored and re measured every 15 minutes to make sure that a constant flow rate is maintained.
Interpret your water test results many well owners need help understanding water test results.
A home inspector will sometimes run the water flow test while performing the home inspection.
The shutoff flow will always be 0 gpm.
One way to understand your results is to ask the lab that did the testing.
