The folks that built my little brick bungalow in the midwest back in '54 didn't screw up everything. Most of it is pretty solid.
The 2 24k certified time bombs I'm aware of involve drain pipes in kitchen and bath that were sealed inside the wall.
The bath hasn't failed quite yet. In the kitchen I've had to tear thru tile and plaster/steel-lath just to find the juncture of a 2" lead drain with a vertical roof-vented cast-iron stack. I'm not even certain how to get the corroded, leaking pipe out, let alone how to get new stuff in, as 2/3 of the length is behind the cabinet/sinktop which can't be moved.
Does there exist 2" flexible drain pipe that meets common bldg. codes for such an application? If so, any description etc would be much appreciated.
