Yes, this is a replacement liner. makes an older pool look new again!!!

​@@IslanderpoolsandspasI take it most older concrete pools can be wrapped with a liner?

This is an original liner pool, not concrete. Putting a liner in a gunite type pool can be tricky unless it has a geometric shape.

The winterizing of the filter is the same. Ingrounds need to have the lines blown out though.

thank you @@chrisdibianco2518

These instructions are how to close aboveground pools which do nota have underground lines and therefore do not need antifreeze.

You backwash and rinse your filter first, then drain further using the waste position. When you're all done you should leave the handle between positions up on one of the ledges.

We sell them!

Yes you use the backwash function to drain the pool below the skimmer. Turn your pump off as as soon as the water is below the skimmer right after all the water in the pump is drained you don’t want to run the pump without water in it
