Parallel To Series To Parallel
If you are operating a 2-stage pump in Series and decide to switch to parallel in order to supply more water to additional hoselines, can you do it while still operating or do you have to shutdown. If you can do it while still operating does the pressure on the hoselines drop and would an automatic govenor compensate to maintain the pressure? Conversely, does the pressure on the lines increase if you drop from Parallel to series (should cut volume by half and increase pressure unless govenor compensates).
Never had to do it but wonder what would happen
