What is the best way to find a leak in an above ground pool?

Question

I have an 18 foot round above ground pool. It will lose aprox. 3 inches of water a day. It drops to just about the return ‘eye’ ball then stops. I would have thought it would be somewhat easy to find once it reaches it lowest level, but I can not find a hole or rip or split in the seam at all.

Also, it does not seem to be coming from either the strainer port or the return.

Any suggestions?

Answer 1

The only thing I can think of is to fill it up above where you know the leak is and then put a handful of leaves or other light things into the water and watch where they go.  I would think they would drift toward the leak.

Answer 2

Evaporation?
