This will be my first time closing my in-ground pool and I am having one line that I'm not able to blow out with my shop vac.
This line is one of the two pipes that are at the bottom of my skimmer (there is only one skimmer).
I have drained the pool below the returns and I blew out all return lines and the suction line that goes from the skimmer to my pump.
The only line left is the other line that exists at the bottom of my skimmer. I'm not even 100% sure what this line does/where it goes, I am guessing that it goes to the main drain at the bottom of the pool. If I try to blow it, I don't see any bubbles coming from the main drain. If I try to vacuum this line, water just keeps coming out and it refills itself always to the same level. There was a gizmo in this hole when I opened the pool and there was antifreeze in the gizmo, so maybe I don't need to blow it, just pour antifreeze in it? The other line going to the pump from the bottom of the skimmer was plugged when I opened the pool.
I should also mention that I don't see anywhere in my pool shed where the main drain line is fed back to the pump or anywhere for that matter. I have disconnected all lines I see in the shed and have figured out where each one goes, but nothing going to/from the main drain at the bottom of the pool.
So just need to figure out if I just pour antifreeze into the gizmo that's plugged into this mystery line and be done? Or should I do any more investigating? I am in Canada so need to be ready for very cold winters.
Thanks for any help!
