Do I need to worry about a Lead Bend?
I have a slow running shower drain in my condo and my plumber wants to open the ceiling of the condo below me to replace the pipe. I've heard that there are lead bends and things in the pipes that make it dangerous to use a snake because they could damage the plumbing. Do I need to worry about this? As far as I can tell from internet searches, lead bends are for joining toilets to soil pipes.
Also, is it reasonable to open a ceiling to replace a pipe where we're not even sure that's where the clog is? Aren't there cameras for this kind of thing?
Thanks!
