I'm getting a 27 feet round above ground pool for free. I have to take it apart myself (with some help), what tools do I need to do this with? Thanks.

Be sure to get your site ready. You will need to remove the sod and get a solid base with undisturbed soil. Then have a minimum 2 inches of brick sand level. Now go to the site. Most pools you will need a philips screw driver and 7/16 socket and wrench along with a pipe wrench. Once you drain the liner besure not to let it dry out in the sun or it will shrink and may even crack. Check out some videos on YouTube. There are a few that will explain the install and you can imagine how todo the reverse.
