Liner leak detection?
I appear to have one or two leaks in my new pond and stream. Can you give me some advise on how determine the leak locations?
I probably got a little ahead of myself and started placing rocks and plants to hide the liner before doing a serious water holding check. The ~750 gal pond appears to be losing almost 3" per day (only 1 day check so far). I think it lost even more when I had the waterfall/stream running for 8 hr. I don't see any dampness at the pond rim but it is 2 ft deep. Most of the stream is a little damp but I had watered the plants (back to getting ahead of myself).
I am realizing it may be difficult to find the leaks. This is 45 mm epdm liner with an underlayment of carpet in the pond and most of the stream. The waterfall is lined. I suspect that I might have a loss in my waterfall section where it spills from a mini-me, but I have temporarily stopped the pump to focus on the pond leak which sounds almost impossible to spot.
What tricks have you all used? I tried searching 'leaks' and didn't find much.
