My 87 has 2 valves.
1st valve is at exit of waste tank.
2nd valve is at end where the "stinky slinky" connects.
The toilet is the only thing that dumps directly into the big tank.
Everything else drains to a pipe that connects between the 2 valves.
If both valves are closed, the gray water backs up to into the tank thru a vent line.
