Old Liner Under New Liner

I have bought a new 25 gauge liner and a new Blue Rhino cloth like pad. Can I cut the old liner and put it under all of the above at the bottom of the pool e. g. not up the wall?



Hi Eugene. There are pros and cons about using the old liner underneath the new one. They can be a good barrier against grass, weeds, tree roots and bugs. But they can also cause wrinkles. If the old liner is still pliable and will lay down flat and smooth I would say go for it. Many times when the liners get old they become very crusty. As soon as the water is out they also shrink. Trying to get an old shrunk up crusty liner to lay flat can be next to impossible.

I have used old liners a lot underneath a sand base. With sand over the old liner it is not so critical that it be perfectly smooth. Since the cloth pads are very thin, whatever you put them over needs to be very smooth. Whatever is underneath the pad is going to show through the liner.

Below is a page with information about installing a liner in an above ground pool.
