This is my first winter with my my IG pool (20,000g) and I had it professionally closed. I still have a couple of questions:

1. When the ladder and step rails are taken out, they leave holes in the concrete. Should these be plugged?? They actually appear to have water in them (maybe from rain). I don't recall them being plugged before.

2. Should the in/out holes on the filter (sand) be plugged or capped (maybe with plastic and duct tape or an elastic of some sort? I remember when I bought the house, the whole filter was covered with a large garbage bag...I expect I'll do the same thing.

3. Where the valves connect to the pump (pump is now indoors) - should that hole be capped as well. I would think to prevent animals or crud getting in there.

Thanks for the advisein advance.
