Stupid Question From a New Owner

OneWagonHo · 05-25-2014, 07:09 PM

I bought a used 2002 Ford EWB Sportsmobile and love it. I have a stupid question though. I took off the screw on cap to the drain for the sink. I went back inside and turned the sink on. It drains, but it isn't draining to outside of the van. I have inspected everything and can't find a back up anywhere. Is there a grey water tank that I am too stupid to find? Any advice is appreciated...

although it depends what floorplan you have a gray tank is standard equipment in most vans.have you looked under the back end

You could easily have a grey water tank. Not sure if it would be installed directly under the sink, underneath the van, inside a cabinet, or underneath a couch.

If you don't know the SMB configuration/model number, some interior pics might help us help you.

Definitely sounds like you have a grey water tank. I think the standard configuration would put it in the galley cabinet under the sink, but as others have said, it could be mounted under the van. TO make it a little more complicated, there is no real standard size for a grey water tank. Ours is small and is located in a little nook between the body and the end of the suspension.

I would look for the end of the drain line, which should have a screw on cap and likely a gate valve of some sort, and then track back to find the tank.

After removing the screw cap you will need to pull the gate valve that Greg mentioned. It should be located very close to the cap.

The handle is sort of T-shaped, immediately to the right of the screw cap as you are looking at it.

The previous owner had broken the handle off the drain release, under the van. He kept a pair of plyers under the front drivers seat to pull the screw which pulls the release.

Thanks for the help in trying to figure it out.

I don't think it's on their webstore but if you call SMB West they can send you a new one. I've broken mine twice.

the valve is about 12 bucks at a rv store, I picked up a rock or something on the 101 coming back from Pismo and had mine broken off.

Not wanting to hijack, but if someone could answer....

I have an 08 SMB, and it only has a black water tank, no gray water tank. I've traced all the lines, and they all empty into the black tank, including the sink drain. But in threads like this I see that some older SMBs have gray water tanks. Wasn't there a rule or law after a certain year that RV's have to have gray water tanks? Or am I totally off base here?
