2010 Fuzion 405 Questions

[debob22]

New owner here. My black water from the second bathroom is draining into my grey water tank. Is this normal for this model? Does the 405 only have two waste tanks? Do I leave all three drain valves open when I use the tank flush rinse? Thanks!!

You only need to keep the tank you are rinsing open to rinse.
The grey tank is up front - the shower and bedroom sink. Both other tanks are black - no matter how they are labeled. The kitchen and rear restroom sink as well as the rear throne all use the rear black tank. The front throne gets a tank of its own, and mine came with a rinser as well.
