We have 3 tanks, black, grey & galley. The black & grey (shower & lav sink) tanks have separate valves but share a common outlet. The galley tank is a separate valve/outlet. The black/grey outlet is easily accessible (ahead of the axles on the road side) at all times, but the galley outlet (behind the axles on the road side) is a bit of a challenge with the slide extended.
