I never thought of repairing your Procon pump…. I assume you never think of repairing the pump because it last so long?
EDCO is a Procon Factory Authorized Remanufacturing Center – United States: http://www.edcodistributing.com/pcpumps.php
I have never used EDCO and I assume $40 plus shipping fixes a series 1 pump? (Not sure what series I use for self serve? Series 1 or 2?)
This makes more since for the stainless steel pumps (which I used on my Water Wizard). KR has their prices on series 5 and 6 higher than from EDCO.
