Woke up to water dripping behind my refrigerator. After digging in under the sink to get a look it turns out the toilet was leaking when it was flushed. The 60 year old copper drain pipe wore thin and a hole emerged. Rather than dig up the floor i got it done through the hole under the sink I managed to cut out the pipe and run a new flange past the affected area. There is still a section of horizontal pipe about 6" long I jb welded the bottom to hopefully prolong its life a bit. I probably could have jb welded the hole and the entire pipe where it wore thin It would have been a whole lot easier. Took all day and reminded why I quit my construction career.
