All I hear from people who own these things is how great they are and now Im seriously considering getting one, I've been looking at classifieds of course, and Im seeing a lot of people with "new wet side" or "rebuilt dry side" etc etc.
My question is this. If these pumps are so great, why does everyone have to constantly replace or rebuild parts of them?? Why am I constantly seeing them with replaced / new parts if they are so good?
Is this like an expensive Italian sports car? It's just so awesome when it's not in the shop (too bad its there a lot)?
