I have a 75 y/o 4" cast iron stack that services one bathroom group that needs help. The stack measures 24' from basement floor up through roof. I would like to cut the cast & replace the bottom 8', replacing the san tee & lead closet bend, and re configure the tub & lav drains, eliminating...

Opened up a wall today to find a horizontal 4" cast drain from a toilet with a broken joint. Manage to get all the cast replaced, but everything is urine soaked, and now that the wall is opened up....man does it smell! Looks like it has been leaking for a while. They notices the smell before...

Sorry for the lousy artwork. Dwg shows bathroom plumbing that is failing & needs to be replaced. I want to replace the lead closet bend with ABS. the bend has a vent entering the side of it. My bottom drawing shows how I thought I would do this adding a cleanout & connecting the vent...

I have an older 1920's home with an addition done who knows when. Maybe 40's. Anyway, a cast iron drain was added to drain a half bath in the addition as pictured. It ties into the main stack. The sloped section is about 15' long with about a 4' drop. The pipe is rusted & needs replaced...
