Setterguy the evaporation rates varied by the day. For the most part it was around 0.1 inches most days. That was with high heat and humidity. So I think it was all due to evaporation. Because it recently rained and cooled off a little no loss. And no pump is hooked in to electric. The cost of digging the well is the expensive part. This pump runs constant but if you ever do put in a well I would suggest putting in a float system to make it cut on and off by itself. Would prob save some money.
