Q: How do I know if it’s a leak or evaporation loss?

Dena – Albrightsville, PA

A: A little water loss in your water garden is normal – but when it disappears by the inches, you’ve got a mystery to solve. These step-by-step sleuthing tips, below, can help you deduce whether it’s summertime evaporation or a liner leak.

Step 1 – Look for Evaporation Clues

During the heat of the summertime, you can expect some all-natural water loss. Thanks to evaporation, up to an inch (give or take) of water will naturally disappear from the pond, and if you have a long stream bed with a lot of surface area or a large pond with few floating plants, even more water could transform from liquid to vapor. If you suspect evaporation, fill the pond back up and keep an eye on the water level.

Step 2 – Check for Dampness Around the Pond

If more than an inch of water is disappearing every day, you could be dealing with a leak. Walk around the pond and waterfall or stream, and carefully inspect the soil for signs of unexplained moisture. If you find some, take a closer look at that spot’s liner and construction. Leaking water has to go somewhere, and a patch of wet ground is clear indicator of a problem.

Step 3 – Finding Liner Rips

If you suspect a rip or hole in your liner, keep a close eye on the pond’s water level until it stops falling. When it does, that’s when you should look for the leak. Because the water level will stabilize once it lowers past the hole, you should be able to find the problem at or below the water level and fix it.

To repair the leak, you have two options: repair the hole with a patch found in the EPDM Pond Liner Patch Kit, or close it up with some underwater sealer, like Gold Label Pond and Aquarium Sealer. The patch kit comes with everything you need to fix minor tears in your pond liner, including an EPDM patch, solvent wipe, scrub sponge, seam roller and pair of disposable gloves. The underwater sealer, which works on wet or dry surfaces, instantly repairs leaks in rubber and vinyl liners.

Step 4 – Shore Up Your Stream

If you found moisture outside of your stream or waterfall, turn off your pump and inspect the rocks and liner around the wet spot. Is there a hole in the liner? Repair the leak with your liner patch kit. Is water pooling under rocks or splashing outside the stream? Redirect it back down to the pond with Black Waterfall Foam. Once you apply it, it’ll look like shadows between the rocks.

Step 5 – Inspect Your Fittings

Finally, if you’ve ruled out evaporation and there are no damp areas around the circumference of your pond to be found, the culprit could be your pressurized filter, tubing or connections. Inspect the plumbing on the pump or waterfall where pipe splits or loose fittings could be leaking, and repair it as necessary.

Good luck finding the cause of your pond’s water loss!

A: Dropping water levels and wet patches appearing around your pond indicate one thing: a leaky liner. Don’t worry. It doesn’t mean you need to rebuild your water garden from the ground up. You just have to patch the leak.

Your repair process starts with determining the size of the leak. Smaller holes can simply be patched; larger punctures or multiple tears need a bit more attention. Here’s what we recommend based on the leak size.

For Smaller Holes …

If you have a small hole in your liner that’s 5 inches or less, you can use the EPDM Pond Liner Patch Kit. It contains everything you’ll need to fix minor tears or holes, including a EPDM rubber patch, solvent wipe, a scrub sponge, seam roller and pair of disposable gloves.

To begin, make sure the surface is both clean and dry. If necessary, relocate your fish in a holding tank while prepping the liner and performing your repair. After the patch is in place, you can top off your pond’s water level, and acclimate and return your fish to their home.

For Tears or Punctures …

To repair smaller tears or punctures without draining your pond, you can use Underwater Pond Sealer. Remember, however, that it has to be beaded on, not smeared on, because it’s a sealer, not an adhesive. When used as directed, it’ll start to be tacky in two to three hours, and fully cured in 48 hours. The sealer performs best in water that’s 60° Fahrenheit.

For best results, clean the surface and make sure it’s free of grease and algae. If necessary, relocate your fish in a holding tank while allowing the repaired area to fully cure.

Then place sealer directly onto the surface you wish to bond/seal. Put two 5mm diameter beads of sealer 100mm apart on the overlap. Gently run your fingers over the line to make sure the sealer has connected both pieces of liner. Do not press it flat, and don’t be tempted to pull it apart to see if it has stuck! Allow the sealer to fully cure before returning your fish to the pond.

For Multiple Tears or Large Punctures …

Larger punctures of multiple tears will require some work. You’ll need to put your fish in a holding tank, drain the pond and adhere a new piece of liner to the existing one. Here’s what you’ll need and how the process should go:

First, you’ll need to purchase a liner seaming kit, a new piece of liner and have some protective gloves on hand. After you’ve repaired the tears and ensured that the adhesive had done its job, refill your pond, and acclimate and return your fish to their home.

Good luck repairing your leaky liner!

Abby – Pueblo, CO

A: What a conundrum! Determining whether you have a leak in your liner—and then finding and fixing it—can be a daunting task. But with a little detective work and these step-by-step instructions, your pond will be holding water again in no time.

A Leak or the Heat?

Let’s determine if you have a leaky pond in the first place. How much water are you losing per day? And what’s the temperature outside? On hot days, it’s common to lose up to an inch of volume from your water garden—but if it’s more than that, you may have a leak.

Finding the Leak

Common places for leaks to spring include around the pond’s perimeter, the area around your waterfall and pump, and your liner. When looking for the leak’s source, follow these steps:

Step 1 – Search for a Wet Spot: First, look for wet areas around the perimeter of your pond. Is water pooling somewhere? Are the weeds thicker or the grass lusher in one area than another? Check the low-lying areas where the liner may not be properly supported. If nothing looks amiss, head over to your waterfall pump.

Step 2 – Leak Check: The easiest way to determine whether the leak is in your liner or in your waterfall box is to turn off the waterfall pump (but keep your aeration going so the water stays aerated) and leave it alone for a few hours. When you come back:

  1. Is the water level the same? If so, your liner is not the culprit so you’ll need to check for problems with your waterfall box.
  2. Has the water level dropped? If so, you have a leaky liner. Jump to step 4.

Step 3 – Waterfall Worries: If your waterfall or waterfall box is the source of your leak, follow these steps to determine where the water could be escaping:

  1. Connections: First check the connections from the pump to the box. Are they loose and dripping, or are they tight?
  2. Cracks in the Box: Next, take a look at the waterfall box itself. Are there any cracks? Is the liner properly attached?
  3. Stream Leaks: Finally, inspect the rocks and liner around the waterfall and stream, making adjustments are needed. Try using some Waterfall Foam to stop water from flowing behind the rocks.

Step 4 – Your Leaky Liner: Finding a hole in a liner isn’t easy. But with a little perseverance, you can locate it and repair it. Here’s how:

  1. Track the Leak: Use Pond Logic® Pond Shade to visually track the leak. Simply add a few drops on the side and watch it as it finds its way to the leak. This will take some time, a few attempts—and patience.
  2. Let It Be: If you have trouble finding it with Pond Shade, let the water slowly go down. (Depending how low it goes, you may need to temporarily relocate your fish.) The water level should stabilize, which will allow you to visually inspect the first few inches of liner above the water surface for the hole.
  3. Repair the Leak: Once you find the hole, patch it up with self adhesive Liner Patch or use some Gold Label Pond Sealer.

Good luck with your search!

Finding a Leak in Your Liner – Water Garden Q & A

Q: I opened my water garden up for the Spring/Summer and its seems as though I have a leak? But I don’t know where? Any suggestions? -Several Customers

A: Having a leak in your water garden can always be frustrating. I hope to shed some light on some great ways to detect where your leak is located.

1.) Bottom Leak - The first way to test for a leak is to turn off the waterfall system and check to see how far the water drops. If it drops all the way to the bottom of the pond, then we know for sure that the leak is on the bottom of the pond. This could be caused by a bottom drain or sharp rock edges. It would be suggested to place your fish in another place while checking this.

2.) Side Leak - If the system is off and the water level drops and seems to stay at a certain point, then there is a side leak. The best way to find a side leak is to wait until the water level stays at that certain point, fill the water garden up a 1/2″ or so and go around the edges with a food grade dark colorant or a cap full of milk. By doing this you will be able to see where the dye travels out of the water garden. You may have to shift some rocks around in order to locate exactly where the leak is. A liner patch will easily fix these types of leaks.

3.) Waterfall/Stream Leak – If you turn off your waterfall/stream/pump system and the water level doesn’t drop, then the leak is somewhere within that system. It could be water spilling over the edge of a stream instead of going back into the pond. The fittings on the waterfall or filter could be leaking. The Flex PVC or kink free tubing from the pump to the waterfall/filter could be leaking.
