Holding Tanks question

We are going to run water through next time we use the camper to see what tank is what. Thanks for quick responses!



Hello,
Question about our Forest River Arctic Wolf 315TBH8 holding tanks. One is marked sewage and one is marked waste water. Which one empties/dumps the black tank. Thanks!

Well, sewage should be the black tank and waste water should be the gray tank.
Pics would be helpful and the gray line should be the smaller diameter line, compared to the black line.

My guess would be that the 'sewage' is black water and the 'waste water' is grey. That's just a guess though. You can test it by putting water from the kitchen into the tanks and then dumping it. A clear elbow will help you see when the black tank is empty.
