  1. Is it sufficient to winterize an in ground pool by simply opening up the pump casing drain plug for the main pump, vacuum pump, waterfall pump and spa pump and draining the pump casing?

    1. Do you have 4 pumps on this body of water? if so, then you probably have a lot more stuff to do like clearing the lines, lowering the water level, plugging the skimmer, among other stuff. Just going by the fact you have 4 pumps I would say you have a more intricate setup than most, which means “simply” is not going to be apart of your vocabulary when describing your closing procedure.
