Gray tanks

[popcomeau]

on my cedar creek cottage 2016 i have 3 gray tanks (bath tub, galley and bathroom sink) and 3 outlets valve of course. Are they independant one from the other or when one is full the overflow goes into the next one?

I don't know your actual rig but I have not encountered an RV fitted with a overflow system. it that type of system were installed there would be no need for three outlet valves.

I have never seen one from the factory that had three dump valves that incorporated an overflow into another tank.

Folks have modified to do such but not from factory.
