This may sound odd. I'm trying to save this liner and my pool.
Problem started last year just after we purchased the home. While swimming in the pool the top of the liner separated from the wall and fell into the pool, which in turn caused a big expensive mess. The liner was a few months old, and we're guessing it wasn't put in quite right.
Currently the liner is loose all the way around the pool, its being held in the channel with a insert that goes all the way around the pool. My problem is I don't trust that insert or wedge (whatever its called). I'm trying to avoid what happened last year.
I've read about using boiling hot water to shrink the liner, it may work but I'd still be worried about the liner unhooking during heavy splashing or jumping into the pool.
Would it be ok to secure the top of the liner where it hooks over with small stainless nuts and round head screws (10-32)? Just as keepers so the liner can't unhook....one per top cap section, 24 total. I already installed two where the liner is really loose. These small nuts, machine screws & washers are not holding the liner up in any way, just keeping it in place when the kids decide to do a cannon ball into the pool.
I can take a pic if needed.
The area I was thinking about hardly sees water except when its splashed up the sides. I'm not worried about how it will look, just want it to work.
Is this a terrible idea or will it work ok for now?
