Knowing now what I know about vortechs, I would never buy a used one. You have to treat them like porcelain and hope that the previous owner did the same.
it's pretty lame that people are paying top dollar for a substandard product I'm very disappointed that I have to go through this garbage.
Vortech pumps are certainly not substandard, but caveat emptor when you buy second hand. You have no way of knowing how something has been treated nor how old it is. I'm amazed, frankly, how much people seem willing to spend for these pumps used. Ok, if one is NIB, fine, but I'd never pay more than 50% of retail for any mechanical device more than a few months old.
If whomever you bought this pump from misrepresented its condition, then take it up with them. If they did, or you failed to ask, then the person at fault is the one you see in the mirror every morning.
You can't send the dry side in for repair. Ecotech says the dry sides
are not serviceable. I bought 2 off of R/C, no problems. For $50 you
can rebuild the whole thing. So you do it every 2 years, that's
$25 a year and you can do it many times.
Echotech told me there are no serviceable parts in the dry side. They didn't
repair yours, you got a new one and you should of if it was under warranty.
