Hi! We bought a home with an existing EW/Esther Williams pool. The liner is the original one :/ I would like to replace it as soon as possible...like this week! I found a place online where I can buy a replacement liner, but am confused by the installation. I saw a video on Youtube where it just looks like the guy is 'tucking' the liner into place. Is this correct? It seems to easy! Also, do I even have to remove the railings above? I can't seem to find any obvious screws on them to pop them off. If anyone could steer me in the right direction, I would greatly appreciate it!!!
