Water Coming Out of Vent Line??

I just replaced the laundry sink in my 1940s home. In process I noted what I assumed was a vent pipe (approx. 2" diameter) coming out of basement floor at 45 degree and then turning and going straight up. A joint on this pipe was corroded and came apart; it appeared to be pretty blocked on the interior. I tried to fix it with rubber sleeve with metal clamps. When I ran fist load of laundry, the water emptied from washer into laundry tub but then started coming out of the broken joint, eventually running into nearby floor drain. Any thoughts on why this might be happening and how to fix? Thanks. Tom

I assume that this is old 1940s obsolete galvanized pipe, which is notorious for scaling up inside. Once it does, the only solution is to replace it. (Or cast iron, and you have to replace that, too, once it gets rust-clogged up.) Sorry.
Good Luck!

Have you had the main drain that drains the laundry snaked? I imagine that the volume of water being discharged by your washing machine is larger than the drain is able to handle all at once (probably due to clogs or perhaps corrosion). Since the water can't all get down the drain in one big rush, it will follow the path of least resistance until it can drain...That path may be the 2" vent that came apart on you, and since it came apart the problem is now exposed.

I'd obviously fix the vent, but you might have a plumber come out and clean your home's underslab drains.

I'm not trying to be a smart ass here but you know, you might not have tightened that rubber seal enough.
