So I finally got to closing my pool today and run into some trouble. I am closing it for the first time alone so it took me a lot longer then expected and I did get a bit puzzled with my spa setup and wasn't sure how to blow it out properly. I am still uncertain and I wanted to see if anyone can give me some insight. I will include pics to help my words. So I connected the cyclone vac/blower that I just purchased to shallow end skimmer and started blowing the system one by one. When I was all done I still had two holes in my spa main drain unplugged and had really no idea how to blow them as no matter what setting I put my valves in nothing came out. Same with return jets to the Spa but I was able to blow that with my blower and I plugged them and blower. I then realized I have another pump and a valve on it that I have a manual switch for when I use the spa and blower. So I turned that on and it seemed that it started taking water from the two holes I was confused with but it had nowhere to go and blew out my blower into the sky . good that it is connected with wires or I might have had to search through my neighbor's yards for it. So I figured out where the water goes from those drains and tomorrow I will attempt to clear that again. However, from what I can see this pump and lines/return jets are not in any way connected to my filter system or rest of the pool lines. There are three returns in the spa that I blew out and were coming back from my filter though. I was unsuccessful blowing them out using the skimmer so can I just plug my cyclone to one of the return jets (it has the right size of thread) and blow it from there? I feel that this will just circulate the water back and forth. I think I will have to unplug all the return jets again and start plugging them one at a time until there is only the drains left? Then I would need to plug the drains as air is coming out but there will be some water on the bottom of the spa. Is there some easier way to do is? I was ok with clearing the water from return jets and blower but there was still water in the pump and I assume the lines going to it.
