Danny, Waste thoughts: Head up then down (loop hose) into holding tank - don't want the whole load set up to back siphon against that measly joker valve (buy a spare, change often) Holding tank exit to y valve then either up and out to pumpout or via a macerator pump through hull overboard. While you can put y valve on the other side that doesn't give you a way to dump the tank without a pumpout. Sure you can discharge directly but even in an area that allows discharge it is certainly not polite to do so in the anchorage/marina. Gravity as a way to dump is over rated- you want the tank low to keep the weight down which means whatever portion of the tank is below the water line is not going anywhere without help. On my 35-3 waste tank is under v-berth and y valve and macerator pump are mounted to the underside of v-berth getting them above waterline (make sure macerator pump can 'run dry').
