Replacing 4 inch cast iron 90 from toilet with inlet from tub

[Kevin curry]

Hello, I am updating the bathroom and want to remove the old toilet flange and cast iron pipe. It is a 90 degree that goes to the stack with an inlet from the tub. I only have about 9 inches from the center of the 90 pipe to the bell on the stack so I can’t use a regular 90 and add a for the shower since it won’t fit, any other ideas? I plan to use a fernco to attach the pvc to cast iron.

I don't really picture your situation.

Check out a closet bend/ closet elbow. Can be same size as a 4 inch pipe at the inlet, and mates with 3-inch horizontally. Output can be a hub.

Available in PVC, ABS, and cast iron.

Min distance from toilet flange to closet bend

Does IPC specify any minimum distance from the toilet flange to the closet bend?

I want to replace a toilet in an older home and am anticipating that the closet flange will need to be repaired/replaced. I'm a DIY'er with a lot of experience. I have replaced a different toilet in the home twice, the first time a few years ago replacing the brass ring around the flange and...

The distance to the cast iron is the problem, once I add the 90 you posted and a wye after the 90 for the shower inlet it’s too long and extends past the current toilet flange, something like the attached would fit but isn’t the heel for venting not for the tub inlet?

I think you are saying that you have a cast iron hub that accepts a horizontal pipe. That hub is in line with where you picture the closet flange.

your kinda screwed reasearch some fitting data from charlote pipe the one example of a low heel outlet not good itll work but AFAIK its not legal in that position and likely will cause issues

The idea in the drawing I made was discussed earlier in https://terrylove.com/forums/index.php?threads/is-this-wet-vent-of-a-toilet-ok-theoretical.89201/

It appears to not be OK under UPC, but it may be ok under IPC. Kentucky has their own plumbing code, so don't know about that.

I am confident it would function properly.

The pictures are new. How about photo that show more including the area below the bend that sends the combined waste downward.

Also, why are you looking to remove what you have?
