Have torque t285. We have 60 gallons of gray and thought it was split into two 30 gallon tanks, we investigated and it looks like the kitchen sink and shower go to the same tank and bathroom sink is on its own. Still looking into this, but does anyone know if they overflow the two tanks into each other? Or are they not a split 30/30, perhaps one of the tanks is larger than the other? If not this stinks that the kitchen sink and shower are in the same one.
