Liner too Small
by Glen Short
I have just installed a second hand above ground pool, I have just finished fitting the liner and it seems like it has to stretch at least 300mm either way all the way around to reach the bottom corners. Will it stretch this much? It is the original liner.
Hi Glen. If you are installing a used liner it is a good bet that it will not stretch. Liners loose their elasticity when they are drained and most of the time they will not re-stretch. The best chance you will have is if you fill the pool under direct sunlight, on a very hot day.
In Arizona, under a 115 degree sun, the liner might become pliable and stretch into place.
A quick way to find out is to hook up the wall skimmer and position the liner up against the cove at the bottom. Now go directly across from the skimmer and see if you have enough liner to pull over the wall.
If the liner is way short of pulling over, across from the skimmer, you might as well give up and buy a new liner.
Liner Small For Pool

I'm changing the liner in my above ground pool, 24ft round by 52in high. The liner appears to be too short. There was very little hang over before I started with water and then at about a foot of water the liner pulled away from the wall.
Hi Chris. The liner is probably just fine, it more than likely needs to be stretched more and to have warmer weather.
Liners need to be stretched into pool during the warmest part of the day and in direct sunlight. This softens the vinyl up and allows it to stretch a little. It also makes getting the wrinkles out much easier.
Did you try pulling the liner up over the existing framework of the pool? This allows you to pull the liner so tight that the center of the pool liner is just off the base. You then start adding the water. The weight of the water stretches the liner just enough to pull the wrinkles out, which is also just the amount needed to make the sides fit properly. Some liners are so small they can not be installed using any other method, unless it's about 110 degrees in the shade, then you can about anything you want with them.
I have spent many chilly mornings fighting with cold liners that you would swear are too small. After fighting with them for an hour or so, the sun comes up, the vinyl begins to soften, and they go right in.
The pages below all have photos of a liner being installed in this way.

Another variation of the same idea is seen on this page. It involves using just the stabilizer rods of the pool for support to drape the liner over. This does not work as well as the above method, but it does work.
