Why is my pond loosing water?
1. First of all make sure its not just evaporation. In hot, dry weather and where there is good air movement, you could easily loose 3 or 4 cm of water in a week. Remember that moving water evaporates faster than still.
2. check that the loss isn’t coming from water splashing from a fountain or a waterfall, especially in windy conditions
3. check all hoses and connections for leaks, as well as filter chambers both for leaks or flooding due to blockages
4. be aware of the risk of occasional seepage or capillary action either over the edge of the liner, where the pool is edged, or at certain points along a waterfall. Problems may only occur if the pool level rises, or after the pump system is cleaned. (i.e. the pump is too powerful for the waterfall).
5. is the waterfall shell no longer level or has the waterfall shell become breached?
6. finally, if all else fails, look towards the pond liner. If water loss still occurs with all the pump systems shut down, then wait for the water loss to stop or slow down. This should give you a level to check the liner at. Be aware that the leak may still be somewhat under the settled water level, and the water loss has simply stopped due to water pressure. Check along seams and look for obvious signs of damage.
