2" extra heavy to 2" pvc

[Gs1]

Hi All, I'm a diy'er with some experience. I've cut out old extra heavy cast iron from my bathroom during a remodel. The cast was almost closed not even a screwdriver would clear it. So I'm trying to join the 2" xhci to 2" pvc. I used a shielded coupling but since the xh cast is so much thicker it distorts the metal band. I'm considering leading in a 2" soil pipe adapter. From my understanding with Illinois code a donut or compression type gasket cannot be inclosed in a wall. So I'm lost at what to do. I've had a licensed plumber look and say that's ok. But it just looks like a leak in the making.

What is the OD or circumference of the pipe you are having a problem connecting to?

It's the cast iron the OD is 2.5".

You need the proper sized transition coupling.

I've been having a heck of a time trying to find one. I don't think they make one for 2" extra heavy.

2 inch PVC is 2.375. dang.

maybe I need to file down the cast ridges.

You got the rubber over the heavy CI despite the large pipe diameter. I don't picture a leak developing. I am not a plumber. I would leave it.


Out of curiosity, which way is up? You could lead in PVC, and that would be easier if the second photo is the actual orientation. But still, I would not mess with it.

That's probably what I'll do. Though I did find a 4 band shielded coupling. I don't know if the inspector will like it.
It's in the horizontal position.

it looks fine to me... if you are really worried about it, take it apart and use some silicone on
all the joints to really make an extra waterproof seal..

it will probably last 75 years with or without
doing anything to it....

I heard neoprene roofing cement works better.

A big glob of Pipe dope will work ok too...

I just prefer the silicone because its 100% waterproof

Ok so I did use silicone it is all I had. But just a thin film. I was afraid it would make the rubber slip too much. I did replace the no hub adapter to a medium duty one and I ground down the ridges on the cast. I think I can sleep better now
