main drain pipe leaking

To all,

I woke up this morning after a shower to find water leaking from my kitchen ceiling. Two bathrooms exist on the second floor over the kitchen on the first floor. Needless to say I immediately shut off the water and opened the ceiling (drywall). The ceiling was soaked. I located a half inch crack/split on the main drain pipe from the two bathrooms. The main drain pipe I believe to be at least a 3 inch pipe. The leak is locate near a joint and given the location I believe cutting to be nearly impossible. Is an epoxy my best bet. Or is it necessary to try to cut. Was wondering what is the best solution. I have attached a picture of the pipe and location. Thanks.

I hate to say it but a total re-pipe of the waste lines is in your near future. The waste lines are more then likely DWV copper which is a light weight copper. If you check the rest of the lines both top and bottom there will be soft spots that have a green tint.

i would lay a small piece of copper wire over the hole solider it up tell you you need a repipe, and go to the house
