Hi my plumbing vent is vented into the attic. Is this safe?

Hi Altay...

Code requires that plumbing vents must exit the roof and stub up above the roof between 6" to 24" depending on where you live.

Is it safe for the vents to vent in your attic? Well, if the attic is super well ventilated then it probably isn't going to present any major issues, but if the attic is tight then yeah, this is unhealthy/unsafe and should be fixed immediately!

Back to you...

As Mark indicated, it is an unsafe condition. Has the roof been recently replaced or some remodeling done? Look for a covered over roof opening.

I would like to jump in and also confirm that plumbing vent terminated in the attic is a health hazard. Milo

Thank you for your replies. I am really shocked to find there is no ventilation pipe to the outside on this house. I have just recently had the roof re-shingled. We had 2 Maximums added to our roof. We were up in the attic to see how they had installed them, and that was when we discovered the pipe venting into the attic rather that to outside. I looked in the attic for any holes that may have been cut for the pipe, but there were none. There was just a long pipe lying down on top of the blown insulation... When we moved in 6 years ago, we had it inspected, and there was no mention of this to us or written in the report. There are many vents in the attic though. Do you think that this could be considered "outside" since there is a fresh breeze in there at all times?

I agree with the other experts. Well ventilated or not this is a health hazard. While sewer gas raises with heat and will descend when it's cold. So in summer sewer gas may raise out of a well ventilated attic it will attempt to descend into your house in cold weather. The way I see it you have two options.
1. Run each vent out the roof. **OR**
2. Tie them all together in the attic and just run one pipe out the roof.
Be aware, there's a drawback to this method. If a roof vent ever has to be snaked the plumber has to haul all his equipment up in the attic and locate the vent to be snaked. He then has to cut that vent loose, snake it and connect it back up. All this will add
Considerable expense to the labor charge.
Sooo, What are your plans? Good luck, Tom

Are you sure your roofers didn't pull on the pipe, disconnecting it from the coupling and just threw it to the attic instead of fixing it ? It sure sounds to me like that's what happened... Milo
