How are these tanks set up?

[timurray2000]

Momentum 388M

It seems to have 2 black and 2 grey.
And...there are 3 handles, a black and grey in the side compartment, and another handle under the side near the rear.

I am trying to figure out how the tanks are set up.

I assume the Black Tank 02 is only fed by the rear toilet, however it seems to fill up quickly with little use.
The Black Tank is not filling up quickly with much use.

Where does the laundry empty into? I assume Grey Tank 02?

And about the handles. How do you empty 4 tanks with 3 handles? Is Black Tank 02 and Grey Tank 02 tied to the same valve?

Confused...

If your 388 is like my 381, there are only 3 tanks. There's a front grey for the shower, lav, and kitchen sink and obviously a front black tank. Then there is a rear black/grey tank for the rear commode, lav, and washer hook-up. There is no separate rear black and grey tank. A lot of RV'ers have mentioned a rear grey tank because the One Control panel shows it there. The consensus is the programing for that tank on the monitor panel is more generic for the GD lines as a whole than model specific.

Thanks John. Then that explains why the gauge for Grey Tank 02 never moves.
