When we were out camping last Summer I noticed that the black water tank was filling up fast. I knew we were not woing #2 & #1 that much since they were only two of us. So I got to checking and found that my bathroom sink also goes into the Black tank and I was just running the water like there was no tomorrow. After I discovered this and was careful I found the tank would last a lot longer then before. I don't know why they chose to plumb the system that way. It is on a 2004 Sunvoyager model #83792
