How do find where the leak is in my pond?

Before proceeding with finding the leak within you pond, it is recommended to identify whether the leak is related to the pond liner or pond outer walls, Or to the pond filter or other external pond equipment.
Once you have determined the leak is related to the pond liner or outer wall you can begin troubleshooting.

(We do not recommend turning filtration off during hot summer days or very cold winter days)

Step 1:
With all of the running equipment on the pond turned off, fill the pond to its maximum level and make a note of this level.

Step 2:
Once the pond has been full for 24hrs check to see if the water level has dropped, if the level has dropped mark the liner again and take a note of the amount that has dropped and leave for a further 24hrs, repeat this process until the water level stabilises and doesn’t drop any further.
NOTE: If the water level has not dropped, this would indicate that the water is leaking from you pond filtration equipment.

Step 3:
Once the water level has dropped and stabilised at this level, turn you filtration back on and mark the level of you waterline.
NOTE: Depending on the volume of you pond the water level may drop further when turning the filtration back on, this is normal as a small amount of water will reside within you filtration.

Step 4:
Now that you have identified the level at which the water drops to, this will give you an indication as to where the leak is. You can no proceed checking the water line for a rip or tear in the liner or pond wall. Once you identify the damage mark it and make a note of  and continue to inspect all of the visible (above water level) Pond for damage making marks whenever finding a damaged spot.

Step5:
If you already have a your patch repair kit you can begin to repair the damage, if you don’t you can purchase this from our website:

If you have multiple smaller damaged areas you can cut you patch into smaller patches and repair them individually.

NOTE: We recommend that the patch size is at least 5cm bigger all around the size of the damaged area, this will allow the liner to move and adjust overtime without stretching the patched area.
TIP: When the patch is in place, use Aquarium/ Pond safe silicone around the edge of the patch to give a complete seal around the damaged area. This will also allow for flexibility and prevent the leak from reoccurring in this area.
