Hello TFP. This was my first year owning a pool and thanks to this forum it was a breeze. The advice given in previous threads has been so thorough I haven't had a need to post until now. People I know who have had pools for years are now asking me for advice...
I'll be closing my 27000 gallon Vinyl lined IG pool next week. I have a pretty good idea of what I need to do with the exception of the main drain. My pools main drain is plumed through the skimmer. There are two holes in the bottom of the skimmer. One goes to the main drain and the other to the pump. There is a valve similar to this in the skimmer to control flow http://www.inyopools.com/Products/07...f8GGgIaF_D_BwE
Advice I've seen for blowing out the main drain is to blow air through the pipes at the filter pad and close off the main drain valve once air is bubbling from the main drain. My issue is there is no main drain valve to close off. I can try to blow out the main drain from the hole in the skimmer but as soon as I stop blowing air to try to cap the hole won't the line fill back up with water?
Is my only option to just pour some antifreeze in and cap it off? Thanks for the help.
