I must reroute my venting pipe slightly for my kitchen remodel.
It will be challenging removing the old iron pipe. I assume I will have
to cut them to get them out because I can not turn elbows that are
against a wall, right? I will try to do this with a Sawz-All.
QUESTION: Can I use Black ABS when I reinstall? I would have the same
problem turning elbows to install them. How do I make the connections
between existing iron pipe and new ABS?
Additional Details: The sink is on a peninsula that has a bar about a
foot higher than the sink. The vent pipe goes up from the drain to the
height of the bar and across the bar then up and out the roof. My
remodel requires the bar to be removede and the new height available
behind the sink is now only sink-height. I hear code says that no turn
should be made until 6 inches above sink height when possible... I will
be making a turn to horizontal at near sink heigh the up to the roof.
