didn't work

Well i tried. I read somewhere that if you place a valve (flush king) on the end of your sewer line you could get both gray tanks to fill at the same time. Just keep the flush king closed and open both gray water tanks. This would let shower water transfer to the galley tank. This would give you a lot more holding capacity for the shower. Maybe at the end of the season I'll get under there and do some plumbing.
