Hi, my name is Kathy. I have owned an above ground pool almost my whole life, and my husband and I have moved our pools 3 times! Don't install on a windy day, level cannot be stressed enough, that is very important! Plan to buy a new liner and don't waste time trying to install the old one. Once they have been filled they stretch, then when they are drained and get dry they shrink, so when you refill, the seems will split! Trust me, we learned this the hard way after a lot of work. Also, if it is not a beaded liner, invest in bead track and get beaded liner. Much easier to install, and a lot easier when you have to replace liner. If you have a lot of trees, treat ground for root(we also learned this the hard and expensive way)as we had roots come through our very first pool liner in less than a year! Good luck! Hope you enjoy your pool!
