Finding a leak in your Water Garden
Water Gardens & Features Q & A
Q: I think my pond may have a leak. How do I find it? – Donny of Georgia
A: To find a leak in your pond or water feature, you’ll need to do some sleuthing. Your fish and waterfall/stream will splash some water out of the pond, and some of it will evaporate (especially during the long, warm days of summer), but if you have an average pond and you’re losing more than 3 inches per week, try these techniques to troubleshoot the cause of the leak:
1. Turn off the pump and wait: By shutting off your pump, you’ll be able to narrow down the location of the leak. If the water level in the pond continues to drop, you’ve got a leak or liner breech in the main basin of your pond. If the water level stays the same, you’ve got some more investigating to do.
2. Inspect your plumbing: A leak in the plumbing means you’ll need to carefully examine all the check valve assemblies and fittings, replacing them if necessary. Look at your skimmer and/or filtration system and make sure they’re clean and sound. You won’t be able to check buried pipe, of course, but look around the pond for abnormal wet patches.
3. Check your liner: Your pond’s leak could be caused by a liner breech, either in the waterfall/stream or along the pond’s edge. Has a rock, plant or excess algae growth shifted the liner, causing the water to flow over it? Has the liner settled along the streambed or pond edge after a heavy rain? Do you see wet spots in the mulch or gravel alongside the pond? These clues may lead you to the cause of the leak.
4. Let it flow: If the leak is in the pond basin itself, all you can do is leave the pump off and let the water run out until it stops, being mindful of your plants and fish, of course. Low water levels may force you to net your fish and relocate pond inhabitants. As the water drains, check the sides of the pond for holes or gashes. Look for low edges that allow water to escape and make sure the liner is still in place.
5. Fix it: When you find the leak, we suggest to scrub and remove any debris before patching to help ensure a clean seal. A hole in the pond liner can be easily fixed with and 6″ EPDM Liner Patch Kit or a Universal Liner Patch Kit if you liner is something other than EPDM. Follow the included instructions or contact us and we can help you. If you don’t want to drain your pond to repair the leak you can always use the Underwater Pond Sealer. It works instantly to repair leaks in rubber liners, vinyl liners, concrete, stone, wood, glass and ceramic.
Pond leaks happen, so be sure to regularly inspect and maintain your decorative pond or water feature. Hopefully, you’ll be able to catch the leak before it turns into a flood!
