Looking for the best/easiest way to install new 18x33 overlap liner. We have had leaks in the past and I know we will need to replace the concrete dust that was used to level the bottom of the pool, some of it had to of washed away, so that we will have to tackle once we get the caps off & old liner out. When the original liner was installed they sealed everything off and used a shopvac to suck the liner to the pool walls before putting the water in, but I was hoping there may be some tricks of the trade out there for installing. Thanks in advance.
