Crack in cast iron


What are some options to repair this (short of replacing the entire stack)?

Local code does allow PVC-CI junction, but this piece of CI is in the middle of a bunch of other intersecting pipes.

If there is a leak, I believe it is very very very slow/minimal. This is just guessing from the wood around it; as I just bought the house and opened the drywall.

If that crack is only in the bell, you may be able to cut it out and replace it with a Fernco coupling as a temp repair.

I don't know what the bell is, but this view may help.
You are looking up into the ceiling joists.
I drew an arrow at the crack.
The circles are toilets.
The triangle is where the stack shoots up vertically to vent at the roof.

Also, if by temporary repair, you mean it will last me 20 years, then I'm game.

And what is the consensus on Fernco couplings versus No-Hub coupling?

Fernco is a brand name of a no hub coupling.

That piece in the middle looks like it has been left untouched while everything around it was replaced, I would guess because it was geometrically problematic to replace it without taking up the floor above it. As a homeowner I would be far more worried about it than about a non-leaking crack.

You could always throw some kind of waterproof sealant on the crack (plumber's epoxy, fiberglass, lots of options), but it won't prevent your real concern, which is the crack growing significantly over time. The crack might or might not do that, depending on the stresses on the particular system. My tendency (unless I am replacing the stack around it) would be leave it alone and replace it if it leaks.

But my biggest concern in the picture would be the notching. Those notches look huge from this angle and I would be concerned that they seriously compromise the load-bearing-capacity of those joists. The plumbing doesn't help if the house collapses.

I would want someone experienced with structural issues (ideally an engineer) to say "sister the joists one over" or "you need to add supports to those beams on either side of the notch" or "I am certain that the structural support is adequate."

Disclaimer: I am neither a plumber nor a structural engineer.

Judging by the wetness of the plywood- it looks like you have a bowl wax leak at the toilet. That may be the source of water that shows on your drywall.

Sometimes a casting joint can look like a crack too. As for the off colored fitting- don't worry about it. Seen them before. That double wye is so thick, it'd be another 50 years before it crumbles.

For repairs to a cracked hub- it doesn't exist. Replace is your option.
