Flojet problems


Today, I opened up 5 flojet pumps.  I was thinking that maybe they would be easy to notice what the problem was.  The majority of the problems were with the check valve assembly.  I tried to piece together a couple and got three that probably will not work.  But I did try.  Greg, did say to just buy new ones.  But maybe if I replace them with new valve assembly kits the success would be greater?  I have not check them yet though.  I should be more positive.
