I've been trying for several weeks to close my pool. I've done it steps at a time (the safety cover has been on the most of the time, once the pool was cleaned and water treated). The water level is finally low, so all I have to do is blow out the lines. Therein lies my problem. I can't figure out how to do it. I've read lots of posts, etc., and I still can't get the job done. I managed to blow out the skimmer (from the skimmer back to the pad, using a shop vac). Poured some antifreeze down the tube, tried to blow a bit more and saw red, so I know I'm okay there. My skimmer has two holes, so I figured the other hole was to the main drain. Blew into that, and nothing. Nada. When I took the shop vac hose out of that hole, red liquid came up - the antifreeze. So that hole seems to be connected to the other hole in the skimmer, but not the main drain. I know I can disconnect some pipes at the pad, but can't figure out which one, or how to make it work. None of the piping seems moveable enough to get a shop vac hose near a pipe opening. I also don't know if I need to change the setting on the multiport valve. When I blew out the skimmer, it was set on "waste". Should it be changed to blow out any of the other lines? At this point I've already removed the plugs in the pump.
Here are pictures of my pipe set up, so you can see what I'm dealing with: (note: the booster pump for a vacuum is no longer connected to the system)
Can anyone offer any advice? I'm ready to hire a pool company just to finish blowing out the lines. This is SO frustrating for something I know shouldn't be that hard.
