How do I tell if I have a leak?

[Poconos]

I see you just posted and I do. Let me look around and find the thread with the pics etc and I'll give you the info. Think they're here somewhere but if not I'll post new stuff. Had a deep end leak Spring 2005. Three small slits in a 2" diameter circle. In the meantime go to a poolstore and get a can of Boxer Adhesive #100. Slow acting, won't curl a patch. I will be back.
