soil pipe connection

[bbxrider]

am moving the master bath toilet about 6' from current location. unfortunately the connector for the existing flange elbow has about 3/4" of soil pipe before going into another connector which I have to keep, unless I want re-plumb the entire house. is there some connector like the rubber plumb quik that would take standard 3" soil pipe on one side and the other side a large enuf diameter to fit the od of a 3" connector?

I could take my dremmel and grind down the connector OD enuf so I can fit a plumb quik 3" to 3" connector, but sure if BI will allow that in sacramento ca.

some hearsay there is a tool that grinds out the inside of a connector to a tight enuf spec that I can glue new soil pipe right into the connector??? Any ideas appreciated, thanks

You can remove existing coupling but it's a little tricky.

Check out this video. At about 5:10 into it he peels the pipe out of a fitting.
do the opposite and peel the coupling off the pipe.
Cut the coupling through the middle where the 2 pipes come together.Then split the coupling lengthwise and peel it off

remove pipe from fitting

you can get a ram bit, it will remove the pipe from onside a fitting, it you cant do as David suggests

thanks for the replies, the post where he removes the abs pipe from the inside abs connector is what would work for me. I have done similar before with shower head pipe that broke/rotted off the male adapter in the wall. I hacked sawed down thru even into the threads and carefully peeled out the old pipe. replaced it with a ton of telflon tape on the new pipe. I'm shocked that the abs peeled out in the video. I always thought the glue 'welded' the pipe into fitting making it super permanent. without seeing that video I never would have believed it could be done. also way better that the reaming out wheel. This is abs from 1979 so hopefully the older pipe and its generation of glue will allow the old pipe removal just like the video. of course I don't have luxury of having the fitting out in a vice, I'm working inside my 10" wide trench, but it certainly looks doable.
I'll try to get some good pics and post that back. When this is done i'm curious if the BI will even notice and ask how I got the new soil pipe into the old connector. i'll be sure to use mucho cement!
btw frodo, did you not see my pic?

thanks frodo, nice drawing thanks for all the effort, so now I have 2 choices, peel out the old pipe from the inside of the connector per the video link from Mr_david or Frodo's suggestion to peel off the connector from the pipe??
I guess for Frodo I just cut the connector in half, the one marked 3, hacksaw 2 cuts (marked 1 and 2) for about a 1" section in connector, tap that out, then peel down both sides. The concern I have for this approach is don't have a lot a working room around the bottom of connector in the trench, whereas I have a clean, full view into the connector to peel out the old soil pipe.

my inclination now is to attempt to peel out the old pipe first and if something goes horribly bad with that, I still have frodo's option to peel off the connector from the pipe.

I was also thinking when I start the peeling process for either option to lightly torch the ring to be peeled, thinking some heat (but careful for not too much!!) would facilitate the peeling??

I'm thinking an advantage to frodo's method, is I can still use the plumb quick rubber connector if the old connector doesn't come off clean enough to glue on a new connector

 

[frodo]

no torch, my method. the 1'' piece comes off, then the rest comes off as one piece

it will peel off..by peeling the pipe at the top

it causes the bottom to pull away.....rookie!!!

helpers lean this the first 6 mths on the job

advice,go slow, you are prying, not breaking,

many thanks to all the replies especially frodo for your detail explanation,
I think I have a successful coupling detach, it would appear to be smooth enough to glue a new connector or I could also use the rubber connector.
since my trench width was some what narrow about 9" it was a challenge to get that 'good' angle to really get the screw driver tip aligned to crack the seal with only the small starter slice at the top of the pipe. I cut a second starter slices at 3 and 9 o'clock to get a good angle. and a the bottom 6 o'clock i cut a another line thru the connector so I snapped it off in 2 pieces from either side since it seemed I hit a big resistance zone down there. once that bottom cut was in both sides snapped off real nice.
the pics are not real good but hopefully you can see the work
thanks again
