I can't figure this one out...
I have two vent stacks that run up through the roof. There is no sign of a problem with the flashing. Just above the attic floor (about 2 feet below the roof) there is a fitting that looks like a coupling on both stacks. Both fittings have a slow leak. Are these fittings some type of "check valve"? Otherwise, I would think any snow or rain water that entered the stack would simple drain through the waste line.
And, ultimately, how do I stop the leaks?
thanks!
