Let’s Fix That Pond Leak With 6 Different Reasons.
Having a Pond Leak is challenging and one of the most common problems pond owners face. The frustration mounts when the cause of the leak is misdiagnosed or misunderstood.
Here are six reasons your pond may be leaking:
Evaporation. What is it really?
Evaporation is defined as the process of turning liquid into vapor. So let’s discuss what that ACTUALLY means.
First question to ask is, “Can water evaporate from my pond?”
Absolutely, is the answer! The amount of water loss, of course will vary according to the region of the country and the time of year. Ponds that are located in areas like Dallas, with moderate to hot temperatures and high humidity in spring and summer months, can expect to see 1 to 1 ½ inches of water loss or more per week during the warmer months.
Now let’s ask the question… “Can my pond lose 6 inches of water overnight?”
No, is the answer! It’s important to understand that evaporation is a slow process, over the course of time. With major dips in water levels, you are most likely facing a leak,
Pond Leak Problem: Low Edges
Settling at the pond’s edge is the most common cause of a leak, especially in a new pond. We suggest all pond owners periodically check for low edges around their pond, but even more on a new pond build.
The most common area for “low edges” are often found around the stream and waterfall areas, where settling may have occurred after a few rainfalls. These areas are usually more susceptible because they are built up during the construction of the pond using the soil from the excavation and are prone to some settling.
Carefully inspect the edges of not only your stream and waterfall, but also the perimeter of the pond. Water can escape over the edge of the liner, so look for wet mulch or gravel and muddy areas along the perimeter. If your super sleuthing paid off, you’ve now located the problem area.
Go ahead and give yourself a pat on the back, job well done! A low edge can be built back up relatively easily by compacting the soil beneath the liner, in order to raise the edge above the water level. A quick lift of the liner, pushing some soil under it to raise the edge, and you are on your way to becoming ‘pond master’.
Dam(n) Debris in Streams & Waterfalls
Okay, so there’s no beavers in your pond but there could very well be a blockage restricting the flow of water. Rocks and excessive plant (or algae growth) in the stream may not only restrict the water but also divert it right over the edge of the liner.
Pond plant and algae maintenance are important for keeping the flow running smoothly. Trimming them back in order to let the water pass freely is a simple and easy fix.
Are We Still Experiencing a Pond Leak?
Unfortunately, if you’re not fitting into the categories above and you’re still hoping to solve the problem on your own, you have a bit of hard work ahead of you. We appreciate your tenacity, so what’s the next move?
It’s time to roll up your sleeves and a go for a bold move. Shut off your pump for a day.
What does turning off the pump do? It provides a controlled environment, meaning you’ll be able to determine the approximate location of the leak. Make sure to follow the checklist below in order for this to be effective.
- Make sure the pond is filled to the appropriate level.
- Unplug the pump.
- Let the pond sit for 24 hours.
- If the water level drops, then you know the leak is in the pond.
Confirmation: Water Levels Dropped
It’s confirmed, your water level has dropped. To find out where the Dallas Pond problem is occurring, you will need to allow the water level to continue to drop. The level where the water stops dropping is very likely the level where the leak is located. Concentrate your search efforts around the perimeter of the pond at the level that the water has stopped dropping.
Now this is where things can get complicated, so you may want to consider calling in a pond professional. If you would still like to locate the exact source of the leak, you will need to do the following:
- Remove any rocks around the entire perimeter at the level where the water stopped. You can then carefully check for some sort of puncture, or hole in the liner.
- When you locate the hole, patch it with a liner patch kit.
- Now you can replace the rocks and fill the pond back to the top. (Don’t forget to turn your pump back on)
Ready, Steady, Level
If the water level remains the same, the Pond Leak is not in the pond itself. Get ready to start checking the accessory items involved with your pond system. The pipe, the plumbing fittings and the pump connectors are all possible sources of the leak.
Another possible problematic area is the face plate of your skimmer, (if your pond has one.) If the water level stopped dropping above the bottom of the face plate you should investigate the skimmer. There is a possibility it may not have been sealed correctly.
If the Leak is in the Skimmer- you can follow a few steps to correct it properly.
- Investigate the skimmer face plate without disassembling it.
- Simply move a few rocks around the front of the skimmer and slide your hand behind the liner, feeling for wet soil around the opening of the skimmer. If the soil is saturated, then the face plate may have not been installed properly and might be the source of the leak.
- Remove the face plate, clean the old silicone off the liner, and refer back to the instruction manual on proper procedures for sealing the skimmer face plate to the skimmer. Hopefully, this resolves the problem.
We know just how time-consuming and daunting the process can be to locate the leak on your own. Hopefully, with the help and experience we shared with you in the above steps and tips, you can quickly locate
