I had four of the GM heads on my boat. I replaced them with four individual Vacuflush heads - each head has its own system pump, tank, water feed, etc. I've been getting away from "complete systems" over the years because I don't like having all my eggs in one basket which is why I made all four Vacuflush heads individual - none of them share any components except power, and even then, three of them run on a 12v dedicated battery with its own charger, and the fourth runs on the 32v. system. If I have battery issues, I still have a working head. I did the same thing with my air conditioning - no sharing of anything amongst the individual units which has been a real blessing. When I have to clean something, or replace a part, the whole boat isn't down.
Other than the time a guest flushed a tampon, I've never had any issues whatsoever with the Vacuflush over the past 6 or so years. You can install these yourself, as I did. I've heard of people talk about vacuum leaks, but I've never had one - not even upon turning it on right after installation.
and you can hook the Atlantes to fresh its your choice!
