I moved in about a year and a half ago,
assumed this was a bad solder joint patched
by harry. Just got around to fixin it
surprise, anybody have a clue as to what caused this. I am the second owner and as far as I know the house has always been occupied, no other problems with any of the plumbing, if it was caused by freezing wouldn't the other pipes have been affected ? This is a waste line, should not have had standing water in it anyway.

I am curious as to what our plumbing specialists say. Was the pipe standard wall thickness? What does the inside of adjoining pipe look like? Sorry nothing conclusive, just conjecture and queries.

I’d venture to guess freezing. only because the horizontal pipe certainly looks newer than the rest of the plumbing. (no green corrosion like the rest.) and the weakest point in some copper piping is the seam with which it was assembled. drains do freeze. especially if the toilet was running at one point. that looks like a possibility too seeing the little water damage to the floor below the flange. like if the “trickling” leak eroded the wax ring.

Good call
Cleaner gets my vote some cleaners are sulfuric acid and should be flushed immediately after plugged drain is cleared .

what if the drain was frozen, thought to be clogged and HO tries a little “ram out” sulphuric acid based drain opener. that would super heat the ice, and pipe. maybe even hot enough (from frozen) to pop the poop pipe.

My plumber friend has told me he has been replacing almost a years worth of new construction copper pipes he put in eight years ago. Apparently, there have been several cases of seams rotting out from manufacture error. They get dozens of pinholes along the seam and rot from the inside out. This one could have eroded for a longer period before leaking. Then they patched it.
On a side note, I was remolding a home and opened up the plumbing wall and the cast-iron vent pipe had rotted along the seam. From floor to ceiling, sewer gases were trapped in the wall cavity. The horizontal waste pipe was rotted out along the top, not a seam, the culprit here is oxygen. Impurities at the seam are more susceptible to chemicals and catalyst like oxygen.
