I just got it to pump water... I put it in a clean bucket of water and turned it on..

WHAM... black gunk started flying out the other end! OY!!!



I ran it through its paces and let it rinse itself out and now it appears to be working, but I still ordered a new one. I don't trust it.

My boyfriend seems to think black water means it burned up the plastic inside... and it toasted itself.
