I should however also mention that standard ANSI/AWWA C600... e.g. for water piping also contains the guidance in Section 4.3.9 Flushing, "Foreign material left in the pipelines during installation often results in valve- or hydrant-seat leakage during pressure tests. The pipelines shall be kept clean during installation. Thorough flushing is recommended prior to a pressure test. Flushing should be accomplished by partially opening and closing valves and hydrants several times under expected line pressure, with flow velocities adequate to flush foreign material out of the valves and hydrants."
If you get enough velocity, you might even scavenge out some inadvertently trapped air that arguably could cause problems in hydrostatic testing (see e.g. http:/
