I am probably about to show my extreme lack of knowledge about pool equipment and such but I guess you have to start learning somewhere...fortunately I found this place.

Anyway, I think we have a leak (23,000 concete/plaster pool-at least 25 yrs old) We are having to add water daily...last time I measured we lost an inch in about 8 hrs. We were having some problems with the water not closing off at the bleeder tee but we did get an o-ring for it that DH is going to replace later today but I'm thinking that there may be more problems somewhere else.

I was looking all around the skimmer for cracks and such and noticed at the bottom of the skimmer there is a place that looks like the caulking has come off....I've attached a picture so you can see what I am talking about. Is this supposed to be like that or does that open area needed to be caulked? Could that be where we are losing water? I have no idea about this stuff but did notice this and thought I would ask.

Thanks for any advice!
