Two finger toilet flange?
I am about to install a toilet flange onto a 3" pvc pipe in my basement. I have been reading the postings and see that I have an option of fitting the flange over the 3" pipe or using something called a two finger toilet flange that fits inside the pipe. The waste pipe is not exactly perpendicular (off only a little) causing the outside mounting flange to sit nearly 3/16 inch higher off the bathroom floor on one side. The two finger flange seems to fix this problem.
On the other hand the two finger flange sure seems like a small hole! Will I be in for clogs? If I go with the outside fitting flange I could probably get the flange to sit level with the floor quite easily w/o damaging the flange... the pvc pipe has a little movement in the sand/dirt underneath and the screws would hold the flange down. Will this disrupt the fitting between the flange and the pipe as I would probably be forcing the flange level during the drying time of the pvc cement. I could be making too much out of this problem. Am I headed for trouble with the two finger flange? Clogs etc? If I do get clogs will this possibly blow out the wax ring? Thank you! |

I see Tom's not on right now so I'll give you my experience. The biggest diameter waste "tube" I've found in a toilet is 2 inches.
In other words, the best toilet I've found can flush a 2" ball. ...so if the diameter of the 2 finger flange is more than 2" then it's probably bigger than the waste passage through your toilet... so you should be just fine. Does that make sense? [Do, though, give it another day. Our resident plumbing expert will set you straight fer sherr  ]

"The waste pipe is not exactly perpendicular (off only a little) causing the outside mounting flange to sit nearly 3/16 inch higher off the bathroom floor on one side. The two finger flange seems to fix this problem."
So would shaving the pipe to floor level and installing a regular flange.(Just giving you a option.) Ricks correct, ( although I thought the opening was 2 5/8ths) both flanges would work. "Am I headed for trouble with the two finger flange? Clogs etc? If I do get clogs will this possibly blow out the wax ring?" No to both questions. Good luck, Tom |

Hello, I realized as I was installing the subfloor in my new bathroom that I had cut off the pvc to short. It is slightly lower that the subfloor. Is there a longer flange which will solve this problem or should I remove the floor add a coupling and more pvc to raise the height? Thanks, m2
