Hey All - Closed the pool for the first time this year (few days ago). Blew out all lines, antifreezed skimmer lines, etc.. but I haven't been able to blow out the main drain line with any of the shop vacs I've tried (all the way up to a 6.5 HP shop vac). I've come across a few viewpoints on the topic that seem to contrast each other. One viewpoint which is, it's very important to blow out the main drain (and close valve once air is visible coming from main drain to create the airlock) in order to properly winterize the line and several pool companies I've spoken to locally (in Upstate NY) say they don't blow out the line but simply pour pool antifreeze down it and call it a day (and have never run into an issue). Sitting here wondering is it simply enough to put some pool antifreeze down the line or do I really need to make the investment in something like a cyclone that can blow out the line?
Thanks to you all in advance! Awesome forum.
