1.5 HP well pump [RE-wrenches]

[Travis Creswell, Ozark Solar]

Hi Matt,

I've used quite a few of the SQ Flex's and I they are great.  ZERO problems
to date.  I won't even consider DC pumps now.  I'm sure Todd knows about
them as well.  My guess is the budget won't allow that.  But I'm not sure
about running them with a DR.  The folks at Grundfos might have assumed that
would be a possibility and designed for it.  My suggestions were just
good'ol common sense stuff of how I would go about trouble shooting the
existing pump.

I wouldn't get rid of the old pump until all of the variables had been
detailed and problems resolved.  There might be something else going on and
probably is.  These types of issues often are the sum of several problems.
That kind of surge will bring out the problems fast. And Todd's exactly
right about that being an awful design to begin with.  The square wave of
the DR actually would add to the running amps and I would assume the
starting amps.  Windy could answer that.

Have a good one,

Hey Todd and Travis,

Another way to solve this problem might be to replace the pump with 
something a little easier to handle, maybe like a Grundfos SQ or SQE 
with variable speed/constant pressure. This way you can avoid the 
(absolutely necessary) storage tank and added pressure pump costs, not 
the least of which will be the labor. I don't know how they would work 
with the squarewave, but it wouldn't hurt to ask Grundfos about it.
