Hi,
First time here, but I've been reading all the great advice. Hoping I get some guidance.
I have a 4" ID toilet drain (DWV pipe) that is too low from the finished floor. Additionally, I do not have concrete anywhere near the pipe to mount a closet flange. So, my issue is two fold...
1) I need to add concrete so I can bolt closet flange, and
2) I need to bring pipe closer to finished floor because I can't find a closet flange that has a long tail pipe nor one that will go over the outside diameter of my existing drain pipe. All the inside fitting closet flange at the box stores would be installed too low from finished floor. And, outside fitting flanges (like the original one pictured) are not available.
Since I need to add concrete, my preference is to do this right and avoid closet flange spacers.
So, my questions are:
1) Can I install a coupler or reducer or glue extension pipe to add length to the DWV pipe to bring it closer to finished floor? And, if so, can I then use a 3 or 4 inch closet flange that inserts into or on top of the coupler or reducer or extension pipe? In short, I just want to know if the closet flange can ever go into a coupler or reducer and not leak.
2) When I add concrete around the pipe, do I need to wrap it with foam or can the concrete simply fill all around the DWV pipe?
3) If there's an online source for an outside fitting closet flange, please recommend.

Thanks in advance. Looking forward to your thoughts.
