How To Find A Leak In A Pool Liner Above Ground. When looking for a leak in an above ground pool, the hardest place to find it is somewhere in the vinyl liner. Sometimes pool owners mistake normal evaporation for a leak in the liner.
Run the filter, run the vacuum, skim the top, and brush the bottom and walls. Next, take a slow walk around all sides of your pool… The task of finding it becomes tasking, but you decide.
A leak could be anywhere inside the pool, the skimmer gaskets, returning gaskets, light gaskets, and probably the stair gaskets.
Position it so it's only a few inches out of the water. Run the filter, run the vacuum, skim the top, and brush the bottom and walls. This might take time, since the dye will not immediately move towards the hole or tear in your pool. Large leaks, especially in the liner, are often readily visible, making it easy to spot and relatively easy to repair.
