working on the inlet/outlet placement for my hot tub, i realized i could put a couple of small orifices around the tub at back level for the inlets, which would not be too different from massage jets. i know it would increase the system head and so make the pump work harder, but maybe these little nozzles could get me out of adding the separate jet pump and orifices (my jet needs are modest, this isn't a commercial spa or anything). i would like to know your thoughts.
