[RE-wrenches] Shurflo pump

[Mac Lewis]

Hi Drake,

I'll second Kevin's suggestion that it may be the waterproofing gland.  I
see this as a very weak part of this pumps design and won't ever use that
pump again because of it.  The aquatec SWP-4000 is a very similar pump.
Pump manufacturers should take responsibility for the water-proofing into
their unit.  Under water splices are super easy compared to the
gland/grease mess routine required with these pumps.

As Kevin suggested, bypass the controller and put good ~ 24VDC down there
(using batteries off of your cordless tools works well for this)  These
pumps will pump off 18-20V.

Good luck
