Using the intel from this forum ( thank you! ) I closed the pool today. Of course doing it for the first time left some doubts whether I did everything correctly, so I'd like to confirm a couple of things.
1. I used this air compressor:
the way it works, it has two gauges: one for the tank and another one for the output (the hose). I plugged it in to the pump's 1/4'' input to blow out the lines. What I noticed was the pressure first built up in the tank, then I opened the output valve, and both gauges dropped to almost nothing. However I could see the water in the lines was coming out at the good rate. The question I have is how would I now not to "overdo it" since I don't really know the PSI?
2. I also read somewhere that people don't use air compressors since there is a chance to create too much pressure in the line once it is plugged off. How do I make sure to avoid it? I just plugged a line, and then turned off the compressor, is there a different way to do it?
3. I could not figure out how to add antifreeze to the skimmers, since the pipes were always (almost) filled with water after the skimmer lines were blown. Should I use a separate manual pump to pump the water out of the skimmer after blowing the lines and air locking it?
4. I lowered the water just a bit under the skimmer line to make sure it does not get to the skimmer and the ice won't break the tile:
5. I could not find a way to blow out the main drain: I have two drains, the one in a shallow end, and the one on a deep end. The shallow end drain I did find and air locked. But I found no valves that would make a deep end drain talk to me while blowing out air into the system. What else can I try?
6. Is there a recommended way / link / video on how to fold a solid (strap on) cover? The cover I closed with is quite gigantic, I am sure I could spend a lot less time putting it on if I had a couple of tricks up my sleeve.
