Bathtub drain not properly attached

[A. Dimov]

This house was renovated fairly recently and the tub drain doesn't seem to be properly connected.

Recently water came sleeping out from under the wall next to the tub and we found the drain wasn't properly connected.

We opened up the drain and cleared a big hairball clog, and then shoved the drainpipe back in the hole. It drains properly now but obviously if there is a clog again instead of backing into the tub the water will come out of the bad connection.

What do you think is going on here at this connection?

I am trying to reach in there and chisel around the pipe. The pipe in the foundation seems to be metal and there seems to be a nut but it is encased partly in concrete.

Any advice is much appreciated!

You need to take a better pic of what is going on in the ground where that pvc tailpiece is connecting. There should be a P trap down there somewhere.

You need to dig around that area to show us what's there

There is a p trap but in the concrete. It's filled up with concrete all the way to the top of the nut which appears to be brass. I'll try to chip it out more. How would you chip out all that concrete?

It shouldn't be filled completely with concrete. Most likely it is a cap 1"-2" thick to keep rodents out.

I would use a Hilti chipping hammer. You could also use a hammer drill and drill a bunch of holes in the concrete then do at it with a large hammer

Be careful chiseling there as those water lines are there someplace underground.

Maybe 1st try a hammer and chisel it may break up easily

We're trying with a little hammer drill bit. We got maybe 1/2" down and can get all the way around that nut finally.
Now that the nut is free all the way around, how can we unscrew it?
I can see the deteriorated gasket inside and it's crumbling out a bit.
If I could just unscrew this and put a new gasket I think the connection would be good.
The area is so tight I can't clamp any regular lock jaws around it though. I've got basically my forearms through a little hole in the wall through a cabinet under a tub.

Any ideas how to unscrew this nut? Maybe just saw it carefully off with a cut off bit and a handheld Dremel?

Big thin wall socket.

I looked at all of the sockets in the plumbing section at Home Depot and in the socket wrenches section but didn't find anything large enough. I'll try a proper plumbing store tomorrow.

Try to get a measurement and then look at Harbor Freight. If you don’t have a Harbor Freight then you can order from them online.

Ended up cutting a small notch with a multi-tool, wedging a chisel in there to crack it, which loosened it just enough to unscrew. It only t
I tried screwing a new one on and it works.

Nothing wrong with that, good job.
