I had a new liner installed last summer. The liner keeps coming out of the coping track in several places. Why is this happening and how do I stop it?

Thanks for that question and it’s one of the easiest problems to solve.  Typically the problem is with the track and not with the liner.  Plastic coping tracks deteriorate over time and cold weather will make the bead contract and it’s more prone to popping out.  The inexpensive solution is to get the bead back in the track and then use a plastic strip called liner lock to fill the gap between the liner and the track so the bead can’t pop out.  First you need to get the liner bead back into the track.  You can stretch it back into place but you may need to drop the water level a bit or you may need to pour warm water on the bead to loosen it up.  Once it’s back in the track, just push the liner lock into place and you may never have this problem again.
