Where does my gray water go?

I have a 73' Trade Wind. I have figured out how to dump my fresh water tank, and black water tank. I was told there is no gray water tank, so how do I dump my gray water? Where and how does it exit the system? I have 2 exit ports for waste, one under the toilet and one under the shower behind the port side tire. Thanks for the help. Finn

Fill up the kitchen sink, pull the stopper, and see where the water drains out under the trailer? There is no gray water tank, soit should come out of the same outlet where the black water will drain when you pull open the black water valve.

The grey water drains out of the same hole that you black water drains from. You can attach a garden hose and direct it to a temporary holding tank, if you like. It will freely drain from this outlet without having to release the black water. It's a drain within a drain, if you will. If you block the drain, the grey water will back up into your wet bath or tub, depending on what bathroom layout you have.

You will need to get what they call a "blueboy" drain the gray water into it and then dump it at a legal dump station.

We have a 72 tradewind and have added a gray water tank and new dump valves so we can dump the gray water and black waste tanks separately.


P.S. You sound like me last July when we bought our Airstream, had no idea about tanks, didn't even know we had a black water one. We've learned a lot since then. Keep reading.
