As the un-plumbed pools have gotten cheaper and cheaper, I guess the risk isn't very expensive. If it fails, just buy a new pool, sans filter, hoses, ladder etc.

But I suspect it will fail. You are counting on the inflatable ring not deflating--but it WILL contract as the air inside gets colder and shrinks. Will it still be bouyant, enough to stand up to winds and snow? Personally, I doubt it.

I took mine down every year for the 3 years we used it, washed it with a chlorine solution, dried it, and put it away.

But the 15'x3' basic pool is a lot cheaper now and may be worth the risk.
