Ok, so it is looking like I will need to purchase a new liner. That, of course, leads me to a couple questions. First, according to the dealer the original owner bought it from, the liner for that pool is a hung style. I’m not exactly sure what that is but assume that a molded channel lines the top of the liner than hooks over the pool’s metal frame correct? The dealer wants about 650.00 for a replacement, but I am finding better deals online, but want to make sure I buy a liner compatible with my pool. If I go with a liner that says J Hook style, would that work, is that the same thing? Could I go with an overlap and make that work. Basically, I’m asking what type liner I need to order. The dealer only wants me to buy one from them so they aren’t terribly helpful with this issue.

Also, I’m seeing expandable liners as an option and I am intrigued with this as well. I am doing the install myself, but I do have the equipment to scoop out the bottom and make the middle a foot or two deeper. Any problems with this idea I should consider? Anyone else here done this? One site selling liners noted that wrinkles are common and to be expected with expandable type liners. Is that true? If so, that’s a negative right there. Is 20 mil good enough or must I go 25? Any and all liner info is greatly appreciated!
