I discovered that it appears that my vent stack was completely disconnected above the attic. I'm not sure what to do about it. I discovered this as a result of water damage, after poking around above the fiberglass insulation. I had assumed that it was due to a leaky roof in previous repairs(the second time), but now I am inclined to think it is the vent stack, which doesn't appear to have a cap, as the disconnect is directly above the water damage, and in the attic the water wouldn't have had to run very far.
What is the proper way to connect the pipes. PVC glue? Also, I have sneaking suspicion that the same workmanship may be found elsewhere, as there is another subtle leak above my kitchen, which I haven't been able to track down. Is there any harm in putting a cap or elbow on the vent stack? If I haven't noticed any other problems, eg smells is there any harm in letting it sleep after that?
