Man it appears the grey water is a touchy subject from reading other forums. First off let me explain that there was no food particles in the water. To be safe I even installed a screen over the drain pipe and then ran the flexible hose over that. Water was diverted down an embankment as well. Point was brought up in another forum about the new T.T.'s with outside showers. Whats the difference?? After further thinking I will more than likely just modify the pipe to drain into the black water tank somehow. Only bad think I really learned was to never leave your trash can uncovered. Darn skunk hit us up twice and knocked it over and made a mess. I wont throw can or glass into a fire pit.
