I'm interested to hear more about this. I am getting ready to pull the trigger on a Lorentz PS200 well pump and controller (never used these before). I did some research on the SQ Flex, and concluded the Lorentz would be a good choice, despite the high price.

The pumps themselves have held up so far, and seem to be very efficient. I wish there were more solar direct well pump options, I've tried the ETA pumps, the Sunpumps (which are great for low head, low flow) and am about to try a Monoflow. Any other thoughts?

The first three have failed (in exact order of installation) in about a year. Anyone else experiencing similar problems? I had always heard great things about their equipment, is it time to look elsewhere? Where? Gary Gordon Santa Ynez Valley Solar P. O.
