Road Warrior - RW 413 Holding Tanks

[stevestir]

I have a RW 413 and am trying to reconcile my three inside holding tank sensors listed as Gray 1, Gray 2 and Black. Outside up front I have dump valves for Gray 1 and Black. Out back I have dump valves for another Gray 1 with no label for the 2nd dump valves.

How many holding tanks does the RW 413 have? Is there a Gray Tank 2? It is listed as a sensor inside but no description on the outside. Do I have two black holding tanks? I have two drain pipes one up front and one in back for draining both Gray and Black.

You should have two tanks (1 grey and 1 black) up front and two tanks in the rear (1 grey and 1 black). Many TH owners have found that the dump valves were either miss labeled or not at all. I would recommend hooking up your hoses and identify and label them as soon as possible. Also see if you have another sensor in the garage area.
