Hi all - i live in northern PA, we get a lot of cold and snow in the winter. I have an 18x48 intex ultra frame pool and am wondering if I should winterize and leave it up this winter. Has anyone with the same type of weather had luck doing this and for how long? I was going to use chemicals, pillows and the intex cover provided. Drain the water below the inlet/outlet. I also am not sure if I shoudl plug the holes and if so with what. Any info would be helpful....i don't want to ruin the pool after one year.
