Winnebago adventurer 38Q

On my 2016 the washer empties into the black tank. I am certain it does as I get the warm soapy water out the black tank and of course it fills when I do laundry. Most people when I mention it challenge whether it is really going into the black tank. I wonder if this is the case with other owners of this model or if mine was plumbed bad. The water lines were backward so who knows.

I have seen the tank valves mislabeled so who knows.

Your plumbing diagram shows it goes into the black tank. It's 75 gallons, about 20 gallons bigger than the other Adventurers, maybe because of the washer going into it?
