Removing reducer bushing?

I just had a plumber here to look at my plumbing situation. I'm remodeling a bathroom, and want to move the tub and sink drains. Currently, the tub and sink join into the toilet drain as shown below.



I wanted to move the tub and sink to the opposite side of the bathroom. My thought was to abandon the current tub/sink drain and instead join them with a different branch that services something else, but needs to go from 1 1/2" line to 2" to be able to handle it.

Clothes washer, tub and lav would be on one branch. Washer does NOT have a tub, just a standpipe. If I understand what I'm reading, the washer is then 3 DFUs, and the tub and sink are 3. Which would require a 2" horizontal branch instead of the 1 1/2" there now.

Below is a picture of a tap into my stack. If I'm looking at it correctly, there's a 4" stack with a 2" tap on it, which is immediately reduced to a 1 1/2" line. Is there a way to cut out the 1 1/2" line and replace it with a 2" w/o removing the wye from the stack?

If not, I suppose I'll just cut out the PVC below it and add another branch instead.

The bushing is glued into the Tee and you wouldn't be able to remove it.

I have never done it myself, but others here can tell you how to cut that bushing out. Try a board search for something like "cut pvc hub".

There is a big reamer that can drill out a fitting. Forget the name right now, but it has been mentioned fairly frequently. Might be cheaper to cut it out and put in a new fitting.

"Ram Bit" by Pasco will eat up that bushing, provided you have space to make it work.

err, just google it

Here, I found the previous thread with a variety of ways ...

You can buy a Pipe Shredder bit, or a Rambit, but for a one-off, that's pricey. I would cut the bushing flushing with the hub, cut a little slice with a hacksaw blade and peel it out. put a hose clamp around the hub so you don't break the hub. Been there, done that.

Thanks everyone! I was hoping/praying that there'd be something like that.

It may be a bit expensive for a one time use tool. But I'll use it again when I redo the kitchen. (There's another setup right above this one that's identical.)

I also would MUCH rather pay $30 than have to fool around cutting chunks out of the stack.

bushing

A Ram-Bit won't work with a bushing because the "hole" in it is smaller than a standard pipe, and a Ram-Bit is sized for the i.d. of a standard pipe.

So I suppose I could use a dremel and a vacuum cleaner to enlarge the hole to standard pipe ID?

Not within any acceptable tolerance. But, you could substitute the Dremel for the hacksaw blade and try this:
