Depression On Bottom Of The Pool.

[Trigger]

this weekend I noticed and odd shaped depression on the bottom of my 22" 54" Easther Williams AGP.

It's about 1.5 inches deep and about the szie of a small dinner plate/saucer. My wife and I suspected that we probably had a leak, and the leaking water washed away some of the sand, hence the depression.

However, we can't seem to find the hole, and we don't seem to be loosing any water.

What, other than a leak would cause this depression? It wasn't there last season. If it was a slow small leak, are thier ways to detect small holes? (I've heard of certain dyes that you can put in the water near the suspected lead???).

Is there a way to repair the sand depression?

thanks!

Well, we solved the mystery of the depression.

We discovered a pile of sand beside the pool, and it appears a small animal had burrowed under the pool and it must have caved in, causing this depression. We didn't notice the burrow at first, as one side of our pool is up against a deck. But looking under the deck....there it was. I'll smoke bomb the burrow to ensure nothing is still living in there and backfill the burrow as best as I can.

Short of emptying the pool, is there anyway I can get rid of the depression in the liner?

Just avoid the depression if the liner is not in contact with the sand. If it is in contact you shouldn't have a problem. I once had several depressions and each one was caused by a tiny hole caused by someone wearing water shoes in the pool. I had no further problems for the life of that liner. I had pool crete in mine.
