My pond has a leak. I have not been able to find it yet. My question is is it worth finding and fixing? My liner (45ml edpm) is 7 years old and I live in Chicago. It feels a little brittle. I am wondering if the easier/better route is just to replace it. My pond isn't huge so it wouldn't be expensive and wouldn't take an enormous amount of time...but obviously if I find the leak that is much easier to fix.
