I have one of these pumps and the other day it stopped working.  I took it apart and the fins on impeller had been broken.  I talked to J&L about warranty and they don't deal with any warranty.  they said it was up to me to deal with the company and any warranty issues 

 Anyhow, I have been trying to find a website, email or phone number of Gen X but I have not found a thing.  if anybody knows a way to get hold of the company please let me know. (as I am with out a return pump)
Thanks
Gord
