I have a concrete block house (on slab) dating from 1959. I think it just developed a leak somewhere in the kitchen sink waste line which runs within the block to a cast iron DWV stack (also within the block).
If I just fill pots of water in the sink there's no water on the slab. If I run water through the sink and into the drain line I can't see any visible signs of leakage in anything under the sink. But water starts weeping at the base of the drywall behind the cabinets - water pools at the end of the cabinets.
Needless to say, this is not making my holidays bright!
I'm hoping it's just the elbow in the copper DWV line just inside the concrete block. If not, and I have to replace it farther back towards the vent stack, how much of the concrete can I break out and still have a solid wall? I figure anything under the window is fair game (as there is a header over the window), but there is another couple feet between the window and the vent stack.
Thanks,
Gary
