Why Does my gray water tank have water ?

  I'd repeat the process again and compare results.  there may have been water already in the gray water tank.  I assume the gray water did eventually stop indicating the tank was empty.

  I closed it. I’ll try again but it was like the holding tank was emptying.

  @Tater, was some of the gray tank discharge leftover antifreeze?

  Nope, mine was winterized with air. Going to try again and see what happens. Wierd. 

  Was hoping there was some unknown valve I didn’t know about

  @Tater
  When you say "maiden voyage" I assume you recently purchased your TAB?  Did you winterize it or did the dealer just tell you it had been winterized.  It is possible that the dealer ran water into the gray tank and overlooked draining it as part of the winterization process?

  If this was your maiden voyage, is it possible the water in the grey tank was from a dealer inspection or walk-through?

  It’s possible but it was wintetized. I was there when they did it. I will see this weekend when I drain everything and refill again. Thanks all

  Yes, I guess anything is possible.

  Barring a major leak of some sort, there are only four openings to the gray tank; the sink drain, the shower drain, the hooded exterior vent, and the dump valve.

  As Sharon_is _SAM suggested above, a properly winterized trailer will have a bit of antifreeze in the tank from when the traps are filled, but it should be much less than the quantity you are describing. If I had to guess I'd say Falcon1970 is right about somebody filling the tank and forgetting to drain it...

  @Tater ,  maybe the trailer was not level when originally drained, and you had the tongue lower when you drained it?
