<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>
