I have an inground pool with the main draining coming into the skimmer basket.
I am trying to blow it out, but is very difficult because it is not hooked up to a valve or anything. Attached is a picture of it (I have both holes plugged now for winterizing) (I found this online, but same setup as mine, but I don't use the gizmo, I put in sole empty antifreeze containers)
I am wondering the best way to "try" to blow the line out as the water is pushing down on the main drain still. My shop vac nor compressor have enough pressure to blow it out, and even if I do, won't it just fill back in?
Right now, I put some foam rope down the line and capped it off.
I'm just worried because the only real give in that line is some foam rope.
Theine goes from the main drain like comes into the skimmer at the bottom, which is about 2-3 feet below ground (typical frost line is 3-4 feet)
If the water does freeze? Will I just push down, into where the water isn't frozen, and eventually stop freezing because it is below the frost line?
Thanks, and sorry for all the questions.
Some people up here are saying not to even blow out the line, and some people are even saying not to cap the main drain line (but than water will eventually fill the skimmer basket)
Thanks again everyone, I really appreciate it!
