ATF: Cyclone - 3850 grey/black tanks

[isisrider]

I have read these forums and I am still confused on the valves to dump the tanks. The 3850 has two dump outlets one in front, and one in the rear. There are also four dump valves, two in the front and two in the rear. I would assume that each of the two valves would dump into the corresponding outlets; but after reading some more info I am not so sure about this. Please advise as I do not want to be dumping my first time and end up with a big mess.

Thanks,

I have a new 3800 and the dump valves are as follows from front to back; valve handle one black (front toilet), valve handle two grey (shower and sink), valve handle three grey (rear sink comes out the front connection), valve handle four black (rear toilet) comes out the rear connection.

I have an '11 3850 and that is exactly how mine is..................kinda of a pain and I wish the rear black tank had a built in washer like the front one does.
