I have the 35C as well, four tanks, since we are parked most of the time I like keeping Grey's open so I use two hoses with a Y straight to drain, but I carry and use extra hose sometimes when traveling depending on were drain is one needs an extension or I extend off the Y. I'm going to test my tanks this weekend my guess is the mid black has one of the sinks tied in since it won't last a week with moderate use but the back black will go for a couple weeks.
