wish i could help but i don't anything about sewer valves since my trailer doesn't have a bathroom. if you don't get an answer here i would suggest trying the nice folks over at repairing yesterdays trailers. tons of knowledge over there... thx!
Im doing this. Out the bottom of the floor under the toilet will be the same fitting with the 4pin flange you twist a normal sewer hose end to. The toat will have a 2ft piece flexible of waste hose and the gate valve is on the tote. Couldnt be simpler.
roll out the tote hook up the hose open gate valve. turn on pump and put water in the bowl.
