Liner Slipping from Coping

[matt4x4]

I recommended the water method because it is less danger to the liner than the heat method. My friend just did this on his 35 year old steel walled pool without issues. Heat usually works about as well but can distort designs along the top of the liner depending on how much stretch is needed, it is also more apt to creating a stress point above the water that can split at a later date.

Thanks for all your help but I am still not sure what to do. I have an inground vinyl liner pool and the coping looks like half of a white metal pipe that is laid vertical from the cement deck down the side of the pool (like 2 inches). The liner goes up the wall and the top of the liner has an inch or so liner trim that tucks into a very small gap between the top of the liner (pool wall) and the coping. I don't see a track just a gap a little bigger than a butter knife that the liner is tucked into. It looks like it just needs to be pushed back up into that gap but I don't know how to do it and keep it there.

Thanks again,

Mary

I believe that gap is the part where the liner goes. Can you take and post a picture? I will take a shot of mine and post it later today. I just wrestled the liner into that butter knife width space - it took a little wrangling, but it got in there.
