Hole in Pool Liner

We cant find the leak in our pool and really cant afford a new liner. My husband insists its on the sides. HELP please. How difficult is it to replace?

We have a j hook 21’ aqua leader above ground pool.


Hi. Many people feel the holes are in the sides because the water seems to quit leaking about a foot or so from the bottom, but this is seldom the case. The most common places to find holes are around the bottom edge where the floor meets the wall, or pin holes scattered around the bottom of the pool.

Holes at the top of the cove area are usually caused by a hand vacuum being pushed to hard into the edge of the pool. Pins holes across the bottom are usually caused by automatic pool cleaners spending to much time in one area of the pool.

Holes in the cove can usually be found by closely examining the liner at the area where the wall and floor meet, all around the inside perimeter. Holes on bottom can be harder to find because they are usually so small. Pulling the liner back and crawling under it can sometimes be the only way to see these. Under a liner with pinholes it looks like the sky at night, full of stars.

The pages below will give you a little more help with finding holes and replacing your liner. A j-hook liner uses the same method as a beaded liner.
