I am starting to plan for a project that I would like to start during my summer holidays and need some help with planning work to a cast iron 4 inch stack.
Gutting it all top to bottom would be straightforward but most of the vertical is still in good shape and I am undecided what is the best approach.
The 2 elbows that join the toilets to the stack are the weak links.
Ironically they are the youngest parts in the system. The stack is 60 plus years and is barely marked, save for the 2 toilet elbows, which I am guessing are about 10-12 years old and look pretty beat up on the insides.
Both toilet flanges are lead peened over brass flanges.
Can I change the lower 1/3 or at worst, 2/3 of the stack for plastic and leave the heavier cast on the top 1/3?
Or is all or nothing?
The elbow on the upper level is joined with MG clamps now.
Can it be pulled and new cast line put in and sealed at the T on the main stack line?
Or is it MG always from this point forward?
I thought these joints were lead chalked, but can that be done on a vertical seam?
If I keep the cast, can I replace the lead sleeve and go to cast toilet flange or is it best to stick with the lead and brass flange?
A lot of questions, sorry, but I am really undecided how to tackle this.
The rotting inside pipe view goes with the unpainted cast elbow.
The painted elbow is in the basement and I have not opened that section of the line yet.
Thank you,
