This is my first time having to close my pool by myself. I should have checked here before I worked on it, but I didn't. I was trying to remember my friend's advice and I seem to have done some things wrong.
I am not worried about getting it perfect right now, but temps are supposed to be low tonight, and I am worried about freezing tonight. Please tell me if I need to redo something or do something right away?
What I did:
I lowered the water level below the two return jets.
I turned my pump to Waste and ran it that way briefly in case that helped.
I sucked the water out of the skimmer, so it appeared dry.
I unscrewed the glass and sucked water out of there until it appeared dry.
I tried to stick the shop vac into the lower pipe and tried to blow air into the pipe.
I screwed caps onto the two return jets.
I put a rubber stopper into the one pipe I see in the bottom of the skimmer.
(I was told I am not supposed to use the stopper, but for today it should be okay.)
I unscrewed that cap to let the sand filter drain out.
I put my sand filter setting onto Winter.
I took the pressure gauge and glass inside.
I poured 2 gallons of RV antifreeze into that part that normally gets covered by glass.
However, I was reading the sticky by Jason Lion and I am not sure I blew out part of the lines where I was supposed to? Or was it enough that I could see the skimmer and other part looking dry? I never blew air into that skimmer pipe.
Also I am not sure I poured the antifreeze into the right part... will it travel where it's supposed to from where I poured it?
If I did it wrong, what should be done now? Or will it survive the winter with what I did? I just don't want costly repairs later!
In my location, we do get temps below 10F occasionally.
I do plan to put foam in the skimmer and in the pool itself. And pour anti freeze into the skimmer -- I have not done that part and I should probably rush to do it this evening, right?
I am not sure if I need to unscrew this other glass looking part near the top of the sand filter. I read a post about procedures with sand filters, but I am overwhelmed at the moment.
Thank you so much.
