First post and hopefully somebody can answer this easily. I have a truly horrible broken drain pipe on the edge of a slab. I could not get it from above without quite a bit of destruction and it’s a historic property so I attacked it from the bottom. I am working in a 2x2x6 foot hole dug under a slab porch and the edge of the slab. There is a rotted 90 but they were nice enough to pour the slab around it. I’ve managed to excavate and expose it but the joint is right in the slab. I have cleared the concrete all of the way around it out about 1/2 inch and the pipe actually fell off the bell. I need to remove the rest and have never worked on one of these old joints. I cannot smack it with hammers because of where it is but I can drill into it and up the side of the bell. If I drill holes and use a chisel I believe it will split and I can remove it. Am I correct? I know it was leaded in, will that just break loose? If I can get this piece out I can use a no hub coupler, go to an ABS elbow and I’ll be fine. I’m just concerned with getting the bell out of the space. Normally at this point I would cut it off above the slab and put my coupling in the wall but the piece above the 90 is a clean out that extends out through a masonry and brick facade so that is another difficulty I’m trying to avoid. And the confined working area makes normal methods impossible. thanks for any help

I just installed my water heater and expansion tank using a brass tee, nipples, and 90. I put teflon tape on the threads and cranked down as hard as I could so the tee and 90 line up and right when I fired it up, there are just some small drops coming from the connections. Do those normally stop after a little bit or do I need to tear that apart and make it tighter or use something else to seal? I literally just finished this about a half hour ago so I will see what is going on in the morning.
