How to access vacuum flush units

[Njlarry]

On our 2000 400 the vacuum generation units are under the galley floor.You can see the sides of them by lifting up panels under the center guest room bunk but that gives no access to the tops where the workings are.

It's a real PITA but the bed frame has to be removed.
Good luck.

Thank you. I was hoping that was not the answer. One more reason for me to consider removing the whole setup and converting to the newer electric Raritan fresh water flush heads.
