My pond is overflowing & flooding the yard!
Don’t panic. There are a couple of reasons this could be happening, and it is likely a pretty easy fix.
First, check the basics.
Is the skimmer basket full? If so, empty it. These ponds are so self-maintaining, that this simple step is sometimes forgotten! We’ve been out on many “emergency” calls only to discover that the basket was just jam-packed with debris. It's an expensive lesson.
Is the biological filter overloaded with plants so that it’s pushing water over the back or sides? If so, remove some of that plant material from in front of the weir.
The auto-level device has come loose, become bent, or is otherwise malfunctioning.
Turn off the water source to the pond temporarily to relieve the overflowing. Once the water has gone down to where it’s supposed to be, adjust and tighten the auto-level device appropriately. We have a video in our Help Library on YouTube demonstrating how to do this.
If the problem persists, the auto-level device probably needs to be replaced.
There may be a leak around the pond or water feature caused by settling or water displacement due to plant growth.
Turn off the water source to the pond and allow the water to subside. You’ll need to wait for things to dry out a bit so that you can determine whether any wet spot is perpetual. This shouldn’t take too long in temperatures over 80F.
Check for leaks along the edge of the waterfall or stream. They will show as a damp area along the outer edge or around the edge of the Biofilter. Most likely, maintenance has been neglected and you have a water displacement issue caused by plants and/or their roots. Is the water flow visible all the way from the source (typically a waterfall) to the pond? It needs to be.
You may also have a settling leak, where the edge of the pond has settled a bit over time. This can happen sometimes. To raise the liner, remove the rock around the low spot, pick up the liner and shove a little dirt under it, lay the liner back down and replace the rocks. You should be good to go.
If, after attempting these adjustments, you still have a problem, don’t hesitate to call for help.
