How do I tell if I have a leak?

[rtpatter]

I finally found the leak However, as luck would have it is at the deep end of the pool. Its about a quarter inch tear/hole in the liner.

My new question is this, I went to Leslies and got the Hydro Pool patch kit. However putting this thing on in 8 feet of water is impossible. On my 3rd try I got a halfway decent patch on however the edges were still not glued down as well as I would like but considering my first two attempts were complete failures I decided to leave it on and see if it works. I beleive the portion of the patch that covers the hole should adhere well enough but the edges of the patch will be sticking up just a bit. Is my Polaris going to pull this patch off when it runs over it? After allowing 24 hrs to bond should I place a second larger patch over the orginal patch for double protection although I really hate to do that and run the risk of pulling the first patch off.

If anyone has any advice or experinece with putting these patches on in deep water I would love to hear it
