I have a very basic question regarding plumbing a bathroom sink. I am great with most around-the-house DIY, even electrical. When it comes to plumbing, I really don't have much knowledge at all.
The sewage lines in the home are good old 1970s cast iron. This includes what I believe is a chromed cast iron trap under the sink (See photo). I am unable to connect the sinks tailpiece to the trap because it is about an inch out of alignment. The trap won't budge (I assume its welded into the cast iron?). If I could pull it 1" out from the wall, I would be in business. I tried cutting an offset tailpiece in order to plumb the sink, but even after cutting it to the smallest possible offset, it is more than 1" and won't line up.
I believe the best solution is to just grab a reciprocating saw and chop the whole damn trap off at the wall, then install a flexible fernco coupling onto the cast iron, attach a 90 degree brass bend to the fernco, and then a brass trap / tailpiece to the sink. Does that make sense? Is it up to code? Others told me to just use a flexible plastic fitting, but I know that those are a code violation and I feel embarrassed to leave such shoddy work behind.
Sorry - looks like the forum is a bit buggy at the moment as far as attachments. Here are the photos: http://imgur.com/zimwA,jYGl4#0
(ignore the bend attached to the trap in the first photo)
Edit: Having read a bit more, maybe it would be smarter to just use slip-joint PVC attached to a fernco instead of brass. I had thought I'd need PVC cleaner/glue in order to go the PVC route.
