Bathroom: Cast Iron roadblock removed
I started off this morning trying to brace up the vent pipe so I could cut the cast iron pipe. Once I got started I noticed that the vent pipe was not fitting tightly in the lead flashing. When I started looking more closely and saw some of light leaking around the pipe so I decided to just pull out the CI rather than try to brace it up.
I started hammering away and I was able to drop the vent pipe out. I am planing on pushing up some 4 inch PVC slathered in caulk to seal it to the old lead flashing. Next I removed the old bathroom cast plumbing - it wasn't easy as some of it extended down a wall a foot or so under the floor so I had to wriggle it out. Next I went to the basement to break out the basement portion of the drain plumbing. Luckily, the two month delay meant that the insides of the pipe was dry.
Once I broke off the cast iron from the septic line I capped off the PVC portion leading to the septic tank to keep the sewer gases out. I broke the pipe at the elbows and was able to support the pipe over the heating ducts (saving myself from a major mess). The only cast iron I left is the old upright pipe in the kitchen wall - it is dry and it can wait for a later remodeling job.
Now I just need to clean up the old plaster and assorted debris. Once cleaned up I will need to pull up the remaining supplier and get the new plumbing installed.
