Our family lives in SW Ohio where we've had various types of winters, but definitely lots of ice storms and snow. We're on our 2nd metal-framed pool now because it's a perfect size for our kids, and if they want to dive - there are several in-ground pools in the neighborhood. The last Easy-Set lasted 5 years, and we did NOT baby it. We left it up every winter, did not winterize it, or cover it, I hate to say. We would drain it to a foot or so, and remove the pump/hoses, then completely drain, clean and refill in the late spring. But our water bills are not too high here. The frame held up very well, as did the liner. Every year, we would have a few pinholes that needed patching which was easy. This last summer, the liner had finally become "threadbare" down to where we let the water drain - which was a couple feet from the top, unfortunately. It was strange! Definitely affected by UV and temperature. For this new pool, we are going to use the chemicals and attempt to cover - which is why I'm on here
Good luck to all!
