I'm a first timer with some questions about winterizing (I have read the recommended threads).
First, in order to lower my water below my equalizer line, my water is down to the top of the first step in the shallow end of my pool. I'm worried that if i close it with the water this low, the ground could heave and cause a crack in my concrete. Does anyone know how much water I have to keep in the pool in order to avoid this?
Second, I've attached a rough drawing of my system. Do I blow out all of the lines with my shop vac from the skimmer? Or something else? Then, after I've blown out the lines do i then let the water out of the heater and filter through their plugs? How will I know if i have gotten all the water out?
Third, do I use anti-freeze? If so, how much and where do i put it in? As my drawing shows, my equipment is on several levels (above grade, at grade, below grade). Obviously, I can't put the antifreeze in the vertical lines unless I fill all of the piping. Should I do this??? It seems like a ton of antifreeze would be needed!
Thanks for your help.
