Hi, I misunderstood your water level. Sorry it didn’t work out.

Here’s what I would do. Empty the pool and take the liner down from the sides. Build the complete framework of your pool. Uprights, toprails and decorative caps. Tape any rough edges on the caps. Pull the liner up and over this structure until the center of the liner is off the ground. With high sun start the water filling.

This is how I install just about every liner I do. It is a great way to stretch in a small liner and an excellent way to get the wrinkles out. Using this method I never have to get back in a pool once the sand is smoothed.

As the water fills the liner may fall in on its own or you may need to go around and release it from the caps as it gets tight. When the water get about six inches from the edge you can use cloths pins and attach the liner to the top rail and just let it fill to about a foot from the top. At this point you should have plenty of liner to work with. Take off the tops a few at a time and set the liner.

If the liner is usable this method will get it in. Best of luck, Dennis
