Grey tank Zepplin Z-241

[cvizgo]

I'm looking to see if anyone knows which drains dump into the grey tank and which go into the black. I feel as if one of my sinks is going into the black. If you know the answer to this or where I may find it I'd appreciate the help.

Thanks, Viz

I believe that Seann, one of our current members, has or had a Zep. You might try sending him a PM to see if he has experienced what you are describing.

Next time you dump your tanks, empty as usual. When black tank is empty turn one of your faucets at a time to figure it out. You could due this even right at the start. It would be easier at a full hookup site also. It would be easier too, if you had one of the clear extensions to see the water flow, just my 2 cents.
