How do I mend a pond liner without having to replace it?
We built our coy pong nearly 20 years ago, then enlarged it and relined it about 10 years ago. We are pretty sure the liner has been torn or punctured because the water level drops about 7 inches every time the pond is filled. The pond is approximately 13' x 16' and, honestly, in all likelihood needs a new liner. We would appreciate any suggestions regarding how to find the leak and maybe avoid the labor and expense of a new liner. Thanks so much!
