How do I find a leak in my Ecosystem Pond?
Many times what people think is a leak in their backyard pond is actually a problem with the waterfall. Or it could simply be a malfunctioning autofill device.
When a leak really isn't a leak:
Remember that water wicks up the side of the rocks in your pond, so be sure you are actually seeing a drop in water, and not just wicking action. If the autofill device is not running constantly, then you don't have a leak.
Phoenix pond leak troubleshooting steps
Before spending money for someone else to find the problem, here are some simple things you can do to troubleshoot the issue. Heck, you may even be able to fix it yourself and save some money!
Turn off the water supply to the pond and unplug the pump, monitoring the water loss overnight. If the water level does not drop any further, you know the "leak" is in the waterfall or stream, and is more likely than not the result of plants needing to be thinned, or another displacement issue like shifting rocks on the edge of your liner settling.
Aquatic plants need thinning in a Phoenix pond or stream!
This is an easy fix with a living ecosystem pond built using EPDM rubber. Use an appraising eye to evaluate whether or not your stream is packed full of plant roots. If you've just been trimming off the dead leaves and not actually thinning the root material, chances are, you've located your issue. Sometimes you have to be brutal and thin those babies good! Just don't do this during winter when there's a chance that an upcoming frost will kill what's left of the plants.
Settling leak around the edges of a Phoenix pond
Once that is done, check around the edges to make sure that water is still not going over the side of the liner. If it is, then you may have a settling leak. Again, this is an easy fix. Move some rocks out of the way, lift the liner up, shove some dirt under it, and replace the rock. Viola! Problem solved.
The leak is in the waterfall
If the previous two steps didn't solve the problem, then the leak is somewhere in the waterfall, and you should call your contractor to come deal with it, unless you're really handy and know what you're doing.
The leak is in the pond
If the water continued to drop despite the waterfall being turned off, go ahead and turn the system back on to keep it oxygenated for your fish if it's summertime, and call your contractor for help.
