Wrenching an Old 2-inch pipe
I have a 65 year old house with some galvanized waste lines. I may need to disconnect a series of fittings (or at least the end one) that wye into the closet bend. These are two-inch fittings. They are 22&1/2 and 45 degree els and close (or very short) nipples.
My concerns: Do I have any chance of twisting one of these out with a big wrench, given the age of the pipe and fittings? Am I more likely to break or crush something rather than get them to disconnect? If I try to wrench it, what size wrench should I try (I'll probably have to rent it)?
If something breaks, I'll probably have to replace the closet bend and main stack pipe, something I'd like to avoid.
