Beaded Pool Liner Not Fitting Correctly

We are having a lot of problems with our pool liner. We have an 18x33 oval pool that is 48" high. We are clearly not doing something right and turning it into an overlap liner. I don't think that is gonna work either. Plus we kinda spent every last penny we had getting the liner pad and the liner itself.

So here it goes. We got the liner all up and the three lines that run along the bottom are all even with where they need to be. The middle one running directly down the middle and the two ends running about a quarter way on. All straight and everything. The line that runs along the very bottom where the cove is fits perfectly along the straight sides and there is no wrinkles in the middle. But then the liner sags real bad about 1/2 foot on each side. Then you have the curved ends that the line doesn't reach the cove. It is about 4 inches off each curve and the liner is extremely tight.

I don't know why it is doing this. It seems as almost like the liner is too short in length but too big in width. Our cove is measured perfectly from what it needs to be and the sand is leveled perfectly too. I don't know if we are doing something wrong and not noticing it, our liner is not made right, or will adding water fix this problem?

There is about 2 inches in it now and it doesn't seem to be doing anything really at all different on either side. Should we add more?

Hi Mandy

A lot of beaded liners are like that, long on the sides and short on the ends.

I would overlap the liner. That will make the sides look nice. The ends do not have to be pulled over a lot, just enough to get the coping on.

If the ends are tight you may need some mid day sunlight to warm the liner up enough for it to stretch. Liners will stretch a lot if they are hot enough, make use of the sun.
