Winterizing a jetted bath tub.
From what I can see, all lines slope down to the intake point so I'm guessing the tub is self draining (including pump) which should mean I don't need to do anything. Is this correct, or is there more...

I use a funnel and dump some RV antifreeze in each jet, run the pump and then refill each jet and hope for the best. Not sure if this gets the water out of the pump but no problems yet and we do have minimal heat to the bathroom.
