There are 2 ways an RV down pipe is installed in the tank
1. It is screwed in by the 3 inch pipe threads to the flange mounted on top the tank
2. It is pushed in thru a rubber gasket mounted on top the tank.
I have a tool I built to unscrew the flange. After so many years those threads are stuck tight. Another way to break the flange loose is to insert the 2 toilet mount bolts and install a pry bar and use that leverage to break it loose----counterclockwise. Doug
PS, there are NO 4 inch pipes in an RV.
