How do i reapir and indendation in an inground pool liner?

To repair an indentation in an inground pool liner, first, drain the pool below the level of the indentation. Smooth out the area by using a roller or your hands to push the liner back into place. If the indentation is due to air or water trapped behind the liner, you may need to create a small hole to release the trapped material and then seal it with a patch. Finally, refill the pool to check if the repair holds and the liner remains smooth.
