I purchased this pump to pump water from a shallow well up a hill on our farm. From the first time I turned it on it had lots of cavitation noise. After reworking the plumbing multiple times, I still didnt get it to run smoothly and within a day the pump head broke a pin on the inside of the head that rendered it useless . It took weeks for Dankoff to tell me they werent going to replace it under warranty even though I never ran it without the filter. Their customer service was awful and in some instances even rude. I replaced it with a SunPump that so far, I am completely happy with. SunPumps customer service was great. If you want to pump water with a solar panel. I would highly recommend calling SunPump to see if they have a solution that meets your needs.
