New Cottage 40CFL question

[VicRider]

My wife and I took delivery of our new Cottage 40CFL last week. Really like the new trailer but have a question. In the closet with all the control switches, there is a separate white monitor panel with one button labeled "waste". The main panel has the typical battery, fresh tank, black, grey1 and grey2. The service manager at my dealership had no idea what it was for. I have only three pull handles outside, so only three tanks. Any ideas?

Thanks

I don't have that trailer but my fifth wheel has that panel in the rear bathroom and there is a more valves in the rear under one of my slides. You should check around the outside for other valves.

Thanks. I will.

Did you get it figured out?

Yes. After looking around, there is another pull handle under the slide and it is labeled "Bath". I am assuming it is for the washing machine, seeing as the other tanks have needed emptying and that one has not (don't have a washing machine).
Have a great weekend!
