And in most of the jurisdictions I work in it is flushed with a garden hose only. You'd be surprised by the green grass, asphalt, rocks, sticks, burlap and so I find when it is flushed properly when we tear them apart to find out what went wrong.
I've had the same UG contractor tell me he never flushes them only to have me remind him he always does on my projects. Commissioning project on State Capitol new fire pump recently where we had them flush the UG the day before the pump test (acceptance) because it had not been flushed to 1860 gpm...they only did it after I told the GC he bought the pump if we hear rocks or anything of the sort.

In most of the jurisdictions where we work, if the work is divided as we are discussing, then to hydrostatic test and two flushes are required. The problem for the owner is when a leak occurs or some sort of inspection card goes missing, and then you have two different contractors pointing their fingers at each other.
