We're dealing with one right now. Installed late 2005, the last Lorentz
we installed because it was at the tail end of all the Lorentz
troubles. So 4 1/2 years in residential use.<br>
<br>
We were to pull the pump this morning, but postponed one day because of
heavy overcast. Troubleshooting suggests that the array checks out and
the pump checks out in terms of resistance between phases and to
ground. Low water sensor doesn't check out. We replaced the controller
(good support from Solar Power and Pump in Elk City OK) but didn't
resolve the issue - it's now beyond what the troubleshooting chapter
covers.<br>
<br>
If I learn anything interesting I'll post it here.<br>

Problems with Lorentz pumps have been discussed here before.
Yesterday, I responded to a no water complaint and found that the
Lorentz pump we installed in 2007 appears to have seized up during six
months of non-use (it's for stock water). This is the second identical
failure for the same customer. The pump is in a deep well that it is
unlikely to over pump and there is a low-water sensor too. For those
of you that have installed these pumps, what types of problems have you
observed? How long are these pumps lasting? Thanks any replies.
