I think I found the source of my leak; Can this be it?

Unless I read it wrong .. It sounds liek it was just a pebble under the liner until you recently hit it with the cleaner and caused the hole. Patch it and see if it stops the leak but don't let the detection people off the hook if they are working on a flat rate.

That's definitely the leak - hole size sounds about right for the water loss incurred.
However, the leak detection company should have found this problem pretty much immediately.
Is there a way to get your money back or is it pay first, find leak later, no guarantees?
I guess they'll just argue that they fixed something that was amiss and therefore should be payed.

I haven't given this company a dime yet. They're going on a flat rate, and they've been out to the house three times now. The first two he tried to make repairs to the light and the third they didn't do anything, only to tell me they couldn't find the hole I told them about. After the second visit, I have found they're increasingly difficult to reach by phone, and I have to keep calling to remind them to come out when they haven't shown up like they said they would.

Jen,
Something else to try until you have time to patch is to place a plastic sheet over the hole and drop a sand bag on that to see if it stops. I did that on mine until I figured a way to patch the blasted thing. For the sand bag I used an old pillow case loaded with play sand.
