Did I crack my drain pipe while cleaning it out?

Yesterday I was cleaning out our drain line (kitchen sink and basement washing machine) which I have done ~quarterly for the past couple of years. I was using my Drain Cleaner I got from Harbor Freight: harborfreight.com/50-ft-compact-electric-drain-cleaner-68285
The drain was cleared and when I ran the washing machine no water came up from the floor drain, but I did notice a small water rivulet coming from the pipe where it goes into the basement floor.



I was running the drain cleaner from an entry point to the left (the horizontal pipe).
My questions are:
1. What did I do wrong? Or is this just an old pipe thing.
2. Can I fix this myself?
3. If so, any pointers regarding what terminology I would search?

Is it leaking at the seam just above the floor ?
How old is the drain line ?

That would be a strange place to leak unless the water level was high in that pipe.
Those fittings are like funnels. One dumps into the one below it.

It may be leaking at the red fitting because that fitting is upside down and the packing may be falling out. That pipe and those connections are very rugged and aren't usually disturbed by cleaning.

I think it is leaking at the red point, but it is a bit hard to determine.
The drain line is, I assume very old. We bought the house four years ago, but the house itself is ~100 years old.

Typically with that type of joint..... they would have packed it with jute and then poured in hot lead to form the seal. Then flipped the tee fitting over. With age the lead no longer seals well.

An upside down joint is more of a problem and especially low to the floor like that.
Sometimes you can repack the lead. Other times the joint must be redone.

I would take a mirror and flashlight and see if you can see a crack in the lead.

I think this is the crack towards the wall.

This is another possible crack.
Gotcha. Is there a way to repair the lead seal? or seal the crack?

Looks like steel epoxy or JB weld is a popular fix.

First, I would start chipping and cutting away at the concrete on the back side of the leak are to get the pipe exposed. It looks like you are going to need access to that part of the pipe/joint for any kind of repair.

I agree that the pipe is likely old, corroded, and your snake just finally pushed it over the edge and caused a crack. Also, I've read that painting the old cast iron pipe caused issues with it rusting/corroding faster - though it's probably old enough to have had a suitably long lifespan already.

JB Weld can work if you can clean some of the rust off as a short-term fix. But if part of it has cracked leaked, the rest of the pipe likely isn't far behind. If it's just a few drips, you can certainly get away with a patch for some period of time. But at some point it's going to need to be replaced. Just something to plan for.
