Asheville Newbie's lav sink not draining--separate valve?

[meghanhester]

Hey there,

I found a valve that seems to drain the kitchen sink--is the bathroom sink connected to a separate valve, because it ain't draining.

Any ideas? Thank you much.

Are we sure the Grey Tank is not so full it will not accept more input? I forgot to pull the grey valve in camp last week, and got a raft of grief from my dear one when the sinks wouldn't drain. One quick pull on the grey valve and all was calm . . . carry on.

The kitchen and lav drains met on the left side inside the rear hatch and then go down to the outlet that is connected to the black tank. Looks like a Y. There is no grey tank. If you have a cap on the outlet fitting it will hold a couple of gallons in the drain lines but that is all. If the cap is off the outlet and the kitchen sink drains and the lav doesn't you may just have a clog. Also check the vent stack for the lav. The outlet is on top of the trailer on the curb side right by the rivet line where the curve rear panels and the side meet.
