Cast iron stack weeping at the joints
I Like To Fix
Lead-and-oakum hub joints at seventy years. The leak is usually below the floor before it shows above it.
This is most common in homes built roughly 1940 to 1980. Post-war and mid-century — copper supply, aging cast iron stacks, 60 to 100 amp panels, first-generation central air.
