We start with the most likely suspects, such as leaky plumbing connections, skimmer and filter leaks, and improperly formed waterfalls. If the leak is not found in these areas, and we've ruled everything else out – you've got a hole in your liner. Rather than wasting your valuable time and money searching for the proverbial needle in a haystack, we will replace the liner. This is usually the faster and cheaper way to fix a leak that is in the main part of the pond.
Step Number One: The 99% Rule
Another interesting piece of information – most leaks occur alongside the streambed or around the waterfall, and can be easily spotted by a professional pond builder.
Just check alongside the stream for wet spots in the soil or mulch. If you find one, you can dig in and around the rocks that border the area and see if the water is inadvertently finding its way over the liner’s edge. If so, just build up the edges enough to prevent water from flowing out of the falls or stream. This step is the same thing a professional would do for you but in almost no time, with almost no hassle, you’ve solved the problem yourself.
Step Number Two: What if the Leak’s Not in the Waterfall or Stream?
