Update on my Leak

[Poconos]

Something else I forgot to mention. One way to get some rough idea of the depth of the leak is to measure the leak rate accurately. As the water level approaches the leak level the leak rate should slow. ex: in my situation with an 8' deep end, I topped off the water level and just let it go down about 1' below the skimmer as I recall. I was losing about 3" a day that calculated to be about 50 gallons per hour based on the surface area of the pool. Using a ruler and referencing a known spot like a point on the skimmer housing, I measured every hour or so and computed the rate. In my case the rate did not change indicating the leak was deep. In the limit the leak rate would go to zero at the leak level. I suspect if the leak had been at the 3.5' shallow end the pressure change with a 1' drop would have measureably slowed the leak. Something else I did to see what I should be looking for with the dye was to use a garden hose on the bottom of the pool and start a siphon at the same rate as the leak. Using the injected dye I then knew what I should see as far as the dye being sucked into a leak. I'll go dig up more info in the archives.

Edit: Moving this thread to the 'pool construction and repair' forum. May get more exposure there as a better fit.
Edit: The pics for the leak patching are off the forum so I'll just have to dig them up and type the words. I'll get to that a little later today.

So.....look at my post #9 and see if you can see the 3 pics. This was posted almost 2 years ago so as an update, the patch is holding just fine. Last Summer I tried to peel up a corner and could not. Seems to be stuck real well. If you don't have double sided tape, which I didn't, just use masking tape folded on itself. The PVC pipe was 1.5" and provided the needed rigidity to be able to push on the patch. Hope this helps.

I've been out of town for two days. As per Dennis' advice I added water to try to get the level to 2' but only got it to 19" before I had to go out of town. It's gone down 1 1/2" in two days so it seems that my leak might indeed be on the side in the 12" to 19" (from bottom) level. I'm going to see where it seems to settle at.

Thanks, Al - I'll look at your thread over the next couple of days ...
