Leaking shower drain line? - Lead pipe? How to fix

I'm primarily a painter, but my boss does all kinds of work, including plumbing. There was a leak that a prior plumber supposedly repaired - they claimed it was the toilet wax ring - but we found water leaking from the bottom of the wall - where the lath and plaster wall meets the baseboard.

The wall and ceiling were already partially open cause we had to repair the ceiling from previous leaks. We found the leaking spot and are not sure how to best repair this. We know there is a kind of silicone tape that can be wrapped around pipe but I don't trust that as a sure way to fix it.

Is pipe like this still available? It goes through the floor joist. The leak is right where the pipe passes through the joist. It looks like the pipe was wedged in there and perhaps the house settling over time may have dug into the pipe

You're not going to find lead pipe to fix that. Best bet is to transition into a DWV/PVC. The top end is easy to work with. The end where the lead goes into the cast fitting will be a little tougher.

That lead pipe would need to be removed from the cast fitting and then you can get a rubber fitting to fit between the plastic pipe and the cast.

Hey Pete,

Can I find a PVC with that kind of curve? When joining the pvc to the cast via that rubber fitting, will I need some PVC glue, or will the PVC just sit in that rubber fitting?

While PVC can be bent with heat that isn't an option for most of us. You can buy 45į and 22.5į connectors. You might have to get a little creative hooking it up. Rotating the fitting will change the angel degree some.
