<p class=MsoNormal>I have also installed several Grundfos SQ Flex submersible
well pumps, and had trouble with them, primarily with the control systems, the
low water shut off sensor has failed on several pumps, and the CU200 control
boxes have failed. 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?<o:p></o:p></p>

set up the PV arrays for six Grundfos SQ Flex submersible well pumps on a

about a year. Anyone else experiencing similar problems? I had always heard
great things about their equipment, is it time to look elsewhere? Where?</span><o:p></o:p></p>
