I am doing some work in my 1910ish house in its second floor bathroom. I currently has a Cast iron DWV pipe that is probably 4 inch or bigger. the problem is that while the house is settling -- the DWV is not. Luckily its settling straight down. So on the second floor where the vent has a horizontal section before heading up to the attic and the vent has already past the point where the settling can be hidden (IE: the pipe joints are above the floor joists).
I never noticed before because it was covered by the tub, but when we took it out to replace it we were shocked at the amount it sticks up...
It travels from basement to the second floor then goes horizontal and y's off to the second floor toilet and goes up to the attic. I assume they did this to stay hidden in a wall stud, if so, why didn't they simply line up the two walls when they built it so it wouldn't have to go horizontal at all???? Strange planning...
My first instinct it to start in the attic and replace the entire thing in sections with PVC. But that could be VERY time consuming and/or expensive not to mention dangerous. But as a first project could I simply cut out the horizontal section and Y and replace it with PVC, (this will eliminate the old joints pushing up the floor)? Will the Cast iron above it be too heavy even with weight supporters to the studs? Will I want to replace the rest to the basement with PVC eventually? Thanks....
