Cast iron stack - leaking at the bottom
- Thread starter VDubDan
- Start date
I wouldn't worry about it, too much is better than not enough, it'll soon slow down once it gets to a section with a shallower gradient.
I'd chuck a bit of dry mix concrete around it to hold it in place, there's another joint within a short distance of the bend in both directions, so any movement should be taken up there.
Looks great, well done. No more rust.
