Hi, I belong to a little 50 year-old brick bungalow in the midwest. There's a small bathroom that's never been remodeled. A small sink with a U-trap, drain running horizontally thru tiles into the wall maybe 14" above the floor.
The portion of the drain that runs from the pvc U-trap into the wall is badly rusted and has started to leak.
I can't see anything of the sink drain from the basement. I figger it does a bend and runs (inside the wall and under the floorboards) into the toilet drain.
There's about 4" of horozontal pipe, then a flange that's flush with the tile.
It sprung a leak by the flange. I shine a lite inside the pipe, it *looks* like only one (rotten) piece, all the way to the toilet drain line (maybe 4 ', all inside the wall).
I'm not well equipped to rip thru the tile, plaster, etc, lead-solder (or whatever) the pipe, then rebuild the wall, and I can't afford $1500+ to hire contractor(s). I'm thinkin' maybe some flexible pipe I can insert thru the rotten pipe and an adapter to go from the smaller diameter flex pipe to the 1.25" p-trap fitting. Do such things exist?
If you have any idea how to repair something like this without the proverbial small thermonuclear device, C4 explosive, etc, please help.
Any/all suggestions welcome.
