Hi Folks,
Need some help. I have never had one of these apart and looking for info on how to pull the toilet flange from the black tank. It looks like the flange is ABS welded to a spout pipe that goes into the tank. There does not appear to have any welded fitting on the bottom of the pipe as seen from the inside of the pipe.
Does the tank have a rubber grommet connection that the pipe just sticks into the tank through the grommet?
I tried lifting the flange with 2 screw drivers under it and everything sort of flexed but no movement. I did not want to pull any harder until I knew more how this goes together.
Is there a trick to pulling on the flange to get it to release?
The floor under the bathroom is bad and needs to be replaced. Thus the toilet flange and black tank have to come out.
Any help, greatly appreciated.
Thanks
John
Here is the flange setup.

More likely than not, it will unscrew. See if you can rotate it counterclockwise. Tank will probably have a "donut" bushing for the vent pipe, but the flange will probably have a male or female thread.

It could either have a grommet or the pipe could thread into a fitting that is either glued or spin welded to the top of the tank. Mine appears to be one of the threaded types.
I could get my hand between the tank top and the under floor insulation with breathable membrane covering far enough to touch the pipe. There was thread sealant on my finger tips when I pulled my hand out and no it wasn't poo and the trailer was new.
I didn't have one of the flexible cameras then but if you have one you might see if you can use it by either bending it and inserting it through the top to check or you might be able to fish it between the tank and under floor material like I did my hand..

take a good look inside picture #2
i don't about you guys
but to me that looks like the flange was glued to pipe with black ABS cement
IF so its not coming out of there with out cutting things apart
might want to get a plumber to give an opinion
a grinder or a saw will cut
BUT how do you get the new pieces back together with out leaks
won't be able to slip a new flange stem over the existing flange stem still glued to the outside or inside of the pipe
will have to 'BUTT' them together and use and inside nipple to glue everything together (if you cut it apart)
I can explain it to you.
But I Can Not understand it for you !

If it's like our trailer, the flange is glued to a piece of 3" ABS which is inserted into a rubber gasket.
The ABS no doubt has a coating of scum on the part exposed inside the tank, and is resisting. Just need to pull harder while turning the flange. Worst that can happen is that the gasket gets torn up, but they are cheap.

You can replace the floor without removing the flange, done it many times, including in RV's. It is most likely solvent welded in, and the only way to remove it is to cut it. If the tank is tight against the floor, yu may not beable to glue it back together without replacing everything from flange to tank flange.

I would make a spanner wrench that inserts into the opposing slots and 2 wedges that you can tap between the floor and flange. Rotate the spanner wrench while tapping on the wedges, it should come out.

I can't guarantee someone didn't glue it in place but we replaced the same part a few years back and it just screwed into place than then a couple screws to keep it from unscrewing.

There are only 2 ways the 3 inch DOWN pipe is connected to the Black tank.
1. Rubber Grommet and the 3 inch pipe slips into that Grommet
2. The 3 inch down pipe is threaded and you have to use a long pry bar between the 2 closet bolts '/, in the flange to break the pipe loose.
I have NEVER seen one glued from the factory. Gray tank inlets yes, but not black toilet down pipes. Doug
