Hi everyone:
I'm refinishing my attic and adding a bath with tub, two sinks and a lav. I have archtectural plans and our plan is to run the tub drain and the two sink drains to a vertical lav pipe under the flange. It probably won't be totally vertical and I'll take some caution not to disrupt the flow of each pipe as I do it. This 3" waste line will travel down an existing first floor wall into the mechanicals room of our basement and then need to head towards one of two stacks we have. there are two vent lines running through the roof. I plan to run the wast pipe exposed under the floor joists (they run the opposite way I'm going) to the stack.
My question is about tying into the stack. I've been warned on a few forums not to try it myself and information is scant about how to cut into the stack pipe. It's clearly black cast iron in the attic, but where I'm looking to tie in it's white - maybe galvanized?
Anyway, are there special tools to cut into iron or galvanized dwv pipes (3") here? Or is this a part of the job I should just hire a pro for? Some have commented that I could cause my entire dwv system to collapse if I'm too aggressive with tying into the stack.
Any idea how much it'd cost to get a plumber to tie into the stack once I've run the line?
Many thanks.
