Even so, I can pump a lot of water for $880.00. I bought the inexpensive 2 inch HF pump for initial filling and maintenance, so I would have it anyway. Many ponds around here leak for a year or so, then gradually seal as the clay settles, as rollers are not typically available, and bulldozer compaction takes a while to settle. I will re-evaluate before next summer. Still, the gradual water changes from periodic pumping improve quality and clarity.
