Proper pond maintenance is essential to preventing leaks. Ensure your liner is installed correctly and is of high quality. Avoid overstocking the pond with fish or plants, and regularly clean debris to prevent damage.
If the leak is not immediately visible, try using a dye test. Add a few drops of food coloring to the water and observe where the color disappears. This method can help identify the general area of the leak.
Sealant is best used for small leaks or cracks. You may need to replace the pond liner or seek professional repair services for larger leaks.
It depends on the severity and location of the leak. For minor leaks, you may be able to repair them without draining the pond. However, significant repairs or liner replacement will typically require draining the pond.
