I've used Fernco 2" x 1 1/2" donuts before to connect PVC sink drains into my CI stack, replacing the poorly sloped lead lines. Armed with this dangerous amount of knowledge, I proceeded to chisel out the lead pipe for the bathtub. The tub is out, so I figured I should take care of this while I'm at it.
Once I've got it cleaned out, I realize it looks a little large. Indeed, the 2" donut fits inside with plenty of slop.
The CI has two closet connections, plus two fittings that service a shower and the tub. The closet connections have bells that are clearly labeled SV. The other two fittings don't have a bell as such, and are not labeled. Measuring the opening, it's about 3 1/8" ID, and 3 3/4" OD.
Do I just need to get a XH-sized donut, or ?
I've attached a pic. You can clearly see the SV marking on the closet hub. The part I'm trying to work with has the plastic bags stuffed in it.
