I was cleaning my pumps and noticed this on my MP10 impeller, thinking it might explain some recent mystery tank issues. Do these rust or is this something else?
Do you guys know when the dates of manufacturing are on your units, I wonder if the ones after the cost dropped went down in quality. Cutting corners to compete with the Gyre
It turned out 2 of mine were rusted, since they were past warranty they gave me half off on buying the new wetsides. Not bad since I got 2 quiet drive wetsides for the price of one, I was happy with the outcome.
