I am moving a 2 inch shower drain and the 2 in, fittings do not fit together on old blk. Pipe is 28 yr. old. I assume the old pipe is a Sch. 40 or could it a 80

Hi Capt Bob 20: Schedule 40 and 80 should have the same diameter, meaning, you should be able to use same fitting for both schedules. However, you can always use Flex Seal coupling. This coupling will take care of the possible differences in diameter of the two different schedules.

Can you snap a picture of these two pipes and post it ?

Hopefully it isn't Orangeburg or Bermico pipe.

Is it considerably thinner walled than schedule 40 pipe?

Is it brittle and look like it might be made of tar impregnated paper?

Widdershins,
Is Orangeberg still in use? I remember installing sewer lines made of Orangeberg back in the 60s but haven't seen it around since then. We never used it inside the building for drainage. Just sewer lines. Regards, Tom

I didn't think it had been used since the 70's, but the difference in pipe size has me wondering if it didn't make its way into the OP's house.

I've seen instances where it was used below the slab inside of buildings, so I was wondering if the OP's shower drain is below a slab.

I used the flex coupler to join the pipe together and it worked fine. I still find it strange that the old PVC and the new PVC don't have the same outside diameter. Thank You for the Help.
I know where to go for problems now
. Again Thanks .

Ever since pvc has been in existence, it has had the same outside diameter whether it be sch 40 or 80, only the inside diameter is smaller on 80, which makes no difference with your fittings. Glad you got the problem fixed, but could you please post a pic of the old pipe, just to satisfy my curiousity? Im betting the old pipe is not pvc, but I would like to see it so I can possibly learn something here. Take care. Lee.

Oh, now that I think about it, you said the pipe was black, which would mean it would be abs, not pvc,, but I beilieve they were all still the same standard outside diameter, really thinking it isn't pvc or abs, but maybe some sort of poly pipe was rigged in there,, hard to say, hope you can post that pic. Thanks, Lee.

Not to ramble on, but are you possitive you aren't working with two differrent sizes of abs, possibly 1 1/2 to 2 inch?

The plumber did great work in the house except when he used lead to hold the PVC pipe in the drain flange. When I had to remove it was not very round their but where I tried to join the pipes together was past the elbow.
Thanks.
