Any chance that the pumping system is off during the winter?<br>

<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>

style="color: rgb(31, 73, 125); 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: rgb(31, 73, 125); 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>
