Bathroom Sink pipe to wall broken
I came across this site doing a search for a problem I have, and the people here seemed very helpful, so I thought I would post a question and see if anyone has some valuable advice.
My bathroom sink was clogged; no drainage at all. I let the draino sit in it overnight, but still no effect. In the morning I went to use a small snake to clear the clog, but it poked a hole through the bottom of the trap; it is very old and corroded.
I'm not a handy person, but thought I could change the trap. When I went to loosen the clamps holding the trap pipe on, the straight pipe going to the wall broke! I applied almost no pressure, but it must be pretty corroded to to have broken so easily.
Anyway, I'm very nervous about damaging the pipe BEHIND the wall (which I think is cast iron), so I'm wondering if someone has any suggestions about attaching something to the straight pipe going into the wall that is now broken. There's about 5 or 6 inches of it left, along with the broken bend part.
My brother said this straight pipe is galvanized.
I've included three links below to photos showing:
1. The trap pipe with the hole in the bottom (sorry about all the gunk, it was like that when I bought the house 11 years ago).
2. The break on the pipe going into the wall.
3. The best shot I could get of the fitting of this pipe going into the cast iron pipe behind the wall.
I'm not that handy, and just don't have the $$$ for a plumber right now, so any suggestions would be appreciated. My main worry is damaging the pipework behind the wall; that would be devastating at this point.
