If you have a vinyl-liner pool, you have probably noticed that after a while it sags or gaps at the track that holds the liner in place. This is caused by constant fluctuations in temperature over the winter which can cause the vinyl to stretch and pop out at certain spots (usually at corners or where there is plastic trim in a concrete deck that meets with the pool coping). Most of the time you can pull the vinyl up and snap it back into place in just a few minutes. Just follow these simple steps:
• Boil a kettle of water
• Pour the boiling water directly on the sagging vinyl. To make things easier, have someone pour on the boiling water, while you pull the liner into the track.
• As the hot water softens the vinyl, pull the vinyl up and into the track.
• Use a flat head screwdriver to help hold the vinyl in the track as you pull the vinyl up and into place.
• For longer splits use wooden clothes-pegs, broken in half and placed along the split every few inches.
