Hello, I have a question to see if anyone else has run into this problem and if so what did you do to fix the problem. My aunt asked me to replace her bathroom sink faucet that she said is leaking. When I looked under the sink the P-trap fittings all the way back to the wall are corroded and green. The problem is, is that there is no fitting at the wall to install new p-trap pipes and the compression nut and gasket that you would normally tighten to ensure no leakage. I am afraid to find out just how corroded the pipe is since it is an older house. Has anyone run into this? The only thing I can think of is that I will have to cut around the drain pipe going into the wall and see if there is an threaded iron pipe somewhere in the wall which I would think that there has to be one somewhere. Any help would be greatly appreciated. Thanks

Most likely the chromed pipe is soldered into 1 1/4 in copper pipe. You will have to open up the wall. The corroded chromed pipe will collapse when it is handled.
A pic would help.

Oh, OK I never saw that before, a chrome pipe soldered into a copper pipe. I guess I will have to open up the wall then. Sorry I couldn't take a picture, the camera in my phone is broken, a new phone is on order and I will be getting it in a couple weeks.
