I expected it to be a free pipe just stuck down into the grey tank?
There is no access from below other than the gray tank.
I'm thinking that I need to drop the grey tank.....ug!........or break off the fitting and shove a new pipe down .....but is there something in the tank that would break loose and cause a clog.....or does this plumbing stack fitting connect to a fitting on top of the tank ......I believe the same way the drain valves do?
I hope you all have some answers for me.
Thanks

Mark,
The thing below the floor is the grey tank. A fitting is attached (solvent welded) to the top of the tank to accomodate the pipe. The ones I have seen are slip fit (glued/welded) and not threaded. The only threaded connections I have seen to a tank are the 3" toilet floor flange ones. The little bit of up and down you are seeing is probably the tank top flexing.
If you try to break off that fitting, you are probably going to break the tank.
I think you have two possibilities here. I've done both of these in houses where I needed to fix something without opening up walls or tearing open floors.
First, try to acertain how much room (and pipe) you have between that sani-tee and the tank. If it's several inches, you can cut the sani tee off and simply use a coupler to attach your replacement pieces. When I was in that position I found it easiest to cut the tee flush with the floor and use a cutting wheel on a dremel tool to cut the pipe from the inside.
If there is not enough room there for a coupler fitting, you can try to salvage the pipe by removing the sani-tee. First you cut off the body of the tee leaving the "socket" intact. Then grab the dremel tool and very carefully grind away the remainder of that tee socket leaving only the short piece of pipe from the tank. Once you get close, you can finish it off by hand with sandpaper. Test fit the new tee often and only remove as much material as you have to in order to get the new tee to fit.
In any case, attach any new fittings with Black ABS cement, it is a good filler.
If any of that is not clear, let me know and I'll try to explain better.
