On some systems I will remove the last nozzle on the zone. Primarily zones that are on the narrow parkway strip between the sidewalk and street. A lot of these heads tend to be 5', 8', or 10' nozzles. And they take quite a while to allow the water through due to gpm design. So removing the last nozzle speeds up operation.
