Sorry about that. I see now that info on changing the thetford valves is hard to find. The only info I found was on replacing the valves on an airstream trailer and it shows that they all have 4 screws that attach them directly to a flange on the tank. If I'm understanding correctly, the valve that has a collar on both sides, one side is glued to the down pipe as you suspect, and the other side is a slip joint with a rubber seal that is pulled together at the bottom of the tank by the 4 screws into the flange on the tank. The 4 screws may be difficult to see or to get to.
If this is the case, to replace it would require you to cut the down pipe and use a rubber clamp joint to reassemble with a new valve.
Not sure if any of this info fits your application without having my eyes on it, but if anything else, just food for thought.
