I closed my pool myself for the first time this year. I watched all the youtube videos, read a bunch of post here, and scanned a few other articles online. I live in northern Virginia, so the winters are hit or miss but still not that freezing cold all winter long.
One thing I have not seen or heard is how to actually fill your return lines with Anti-freeze at least any preferred methods or tricks.
I did not drain my water level below my returns, I started to base on some of the preferences on this site but that was a lot of water for me and I rely on a well to fill it back up. Not to mention the solid cover having nothing to rest on.
I use a compressor and blew lines out and plugged while bubbling. So, no way to get the anti-freeze in from pool side of returns this way…at least that I can see.
So, I went to the pump side and the only way I could come up with was removing the Jandy valve cover, which is split between my VAC line and return line. I use a flexible funnel hose and fished it across to the return line so it would pour straight down the return line and then did the same for the VAC line.
Here is my concern; I poured about 2 gallons of anti-freeze down the return line until it started overflowing and about 1 and half gallons down the VAC line till it started over flowing. The return line is about 35-38 foot long and the VAC line is about 28-30.
I can not image only two gallons of antifreeze would filling up the return line and VAC line.
Could this be right??? I am now worried that there is water still in the line, hence the reason why the anti-freeze is backing up. Is there some other reason why the anti-freeze would be backing up the return lines? I’m confused and concerned.
How does everyone else that does not drain below return lines force anti-freeze into their lines. The pool store mentioned something about blowing it through but really didn't give me the details. Any clues how to do this or some other way?
Also, does anyone know how to winterize a slide line. I blew the line out but there is really no way to get anti-freeze from either side of the line.
Last question, will a Jandy valve hold the air lock on the main drain all winter?
