I have a 700-1000 gallon water feature (rough calculation) that seems to lose hundreds of gallons of water in sometimes just ~10 days. Essentially I can lose 1/3 of the water in the feature in just over a week.
- This is definitely more prevalent depending upon how high I have the water pressure and I've tracked some of this down to some spill over. I've lowered the pressure and that helps quite a bit.
- Some of this is definitely evaporation because it is much more severe in hot weather. We have rocks around the feature which bake in our 100 degree California sun, this may be part of it. During winter I don't have these problems nearly as much.
- I'm also concerned that I may also have a leak underground given the amount of water that can disappear. I've also heard from my next door neighbor that they see some damp areas on their side from time to time. It could be from our pond, but I am not sure.
My question is: Is it possible that evaporation is the main culprit here or is it likely that there is a leak?
Follow up question: Who would I contact to do a leak investigation? I've been trying to determine the best way to figure this out myself but if I do have a leak, that part may be over my head.
To add clarity regarding the evaporation: We have rocks surrounding our pond that get water on them, the rocks heat up and certainly there is some amount of evaporation. I would think this would be the most prominent source of evaporation due to the heat that the rocks absorb from the sun, particularly around the area where the water comes out.
