I'm replacing the toilet in a second story bathroom in a 100-year old house. Toilet drain was the normal lead pipe closet bend mated to cast iron DWV stack. The problem is that the house was not designed for indoor plumbing, so the plumbers evidently had to make it up as they went about installing. The space between the floors is so small that there is very little clearance for the plumbing. In fact, the top edge of the cast iron hub on the toilet drain was protruding through the subfloor (through a very nice little hole they cut for it). The hub was cracked and has since been removed. The problem comes in trying to install some sort of closet bend in that small space. The original lead pipe had quite a sharp bend in order to get the flange to the right height, but the PVC I'm replacing it with is not so forgiving. A normal PVC closet bend would place the flange far too high, as would a long sweep 90 or even a 45 flange with a 45 bend. The only thing I can come up with that will fit is called a vent Ell. That arrangement would still put the flange 3/4" above the expected finished floor height, even with the flange sitting right down into the vent ell directly. The only other idea I can come up with would be to cut 3/4" off the vent ell hub and 3/4" off the flange spigot so that when you put them together the flange ends up sitting 3/4" closer to the floor. The problem is this would obviously limit the mating surface area. Does this sound like a crazy idea? I know the other option is to raise the floor, but I really want to avoid that if at all possible.
So, my questions are:
1. Can I use the vent ell instead of a more conventional bend fitting?
2. Can I trim 3/4" from the vent ell hub and the flange spigot to further drop the flange?
3. Anyone out there have a better idea for me? Please?
