<DIV>Doug, </DIV>
<DIV>Thanks for the feedback. I have to install the monoflo, because it was
purchased 2 summers ago, but the customer didn't have the site work done to
install the pump. This summer the site work was finished and now the customer is
ready to have the system installed, so wish me luck!</DIV>
<DIV> </DIV>
<DIV>DC Power is getting out of the pumping biz, so is Wholesale solar up north,
hopefully Solar Depot will remain in it. Our only other option is to go through
the plumbing supply houses.</DIV>
<DIV> </DIV>
<DIV>I hear the bugs are being worked out of the Lorentz pump line, anyone have
any experience with them?</DIV>

<P class=MsoNormal><SPAN style="COLOR: #1f497d; FONT-SIZE: 11pt">Mike, from
another Mendo native, don’t do the Monoflo. DC Power is getting out of
the pumping biz, and we’re the only Monoflo distributor in the US. Our
experience with Monoflo hasn’t been good. We’ve seen a number of pump failures
recently, support from the manufacturer is pretty thin, and troubleshooting in
the field is poorly developed and documented. Basically it’s… pump not
working? Try plugging in a new controller. Still not working? Plug in a
new pump. Dealers don’t keep expensive pumps on the shelf in case of
breakdowns, so repairs usually end up taking weeks. Not good for
dealer/customer relations!</SPAN></P>

<P class=MsoNormal><SPAN style="COLOR: #1f497d; FONT-SIZE: 11pt">DC Power is
getting out of water pumping because we just don’t have the technical
bandwidth anymore. We’re being pressed so hard by the rapidly-expanding
grid-tie market that our tech support crew is getting loved to death. There’s
no time. I’m sorry to see it go, I found water pumping projects challenging
and interesting, but the tech cloning project has hit some snags.</SPAN></P>

<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?</P></DIV>
