Joining Sewer Vents
Hi all.
In the attic of my new house I have two PVC sewer vent pipes that come up from the floorboards. One of them is run completely through the roof. The other terminates about two feet up from the floor into the attic. Would it be feasible for me to put an elbow onto this pipe, extend it over and join it with the pipe that goes through the roof. I would like to avoid putting another hole in my roof for obvious reasons. I'm not sure about the codes in my area, but I imagine that this would not be a problem. I would appreciate opinions. Thanks, Scott |

Thanks, Scott Looks like the builder "forgot" to finish the job. (Might want to verify somehow that this pipe is actually a sewer vent. Listen at the opening for running water when flushing, etc.) Yes, should be fine to connect them as long as the existing one thru roof is full size (4"). Slope the horizontal part of the extension so that it rises toward the vent you'll be connecting into. Jim |

Joining Sewer Vents
I don't think so. I'm not a plumber, but I see houses with 5 and 7 vent
pipes in the roof. If the builder could save roofer costs by having the plumber joining all the vents (lesspenetratyions to seal), I think they would. Any plumbers out there...agree, disagree?

If they're both really sewer-vent stacks, then last time I checked, you could connect them. (subject to some rules involving flood-levels of connected fixtures that aren't likely to affect you in an attic.) Are you sure that's what they are, though? It would really suck to find out after the fact that one of them's actually venting your laundryroom, or a bathroom. |
