Why is there a metal pipe sticking out of my roof?
Question:My house has a metal pipe that sticks out about 18 inches from the surface of my moderately pitched roof. This metal pipe "connects" to a PVC pipe in the loft space above my garage and then "connects" to another PVC pipe at my garage's utility sink/washer hookup. (I put quotations around 'connects' because the pipes do not line up very well, and sometimes even come apart from each other.) I'm hoping that I can remove this pipe since I plan to convert the loft space into a finished living space, and the pipe interferes with installing insulation and putting up drywall. If anyone has any ideas, I would greatly appreciate hearing them. Thanks! :)
Answers:
That is a drain vent and you dont remove them
Im thinking you are talking about a ventalition pipe, and it has something to do with plumbing.
hi
these are vent pipes for sewer gas to leave your house. most homes have them. if you remove them, you will most likely get sewer gas in your home. This is very dangerous to breathe and smells very bad.
You need to call your local plumber and have him move it to a new location or just at least ask him questions
Yes, it's called a stack and it allows sewer gas to escape out of your plumbing. Don't mess with it. You'll start getting all kinds of smells and little flies in your house. I don't know if it also facilitates flushing and draining by providing air. You could relocate the pipe by running it inside a bulkhead that you would build around it. Call your plumber if you don't believe me. Also, look it up on the Internet. plumbing stack/sewer stack
it's a vent stack to vent off the sewer gas (methane)
It's probably a vent. It's a basic law of physics that only one thing can occupy a given space. As water goes into your septic tank, air needs to get out via the vent pipe. You can build a fake pillar around the pipe in the attic, but it should probably stay.
I'm thinking that the metal pipe you are referring to is actually a lead flashing. They look like this: http://www.stovesonline.co.uk/wood_burni...
The lead flashing is the first picture. It actually slips OVER the PVC pipe, and then the lip of the flashing curls over the PVC pipe. They fit loosely usually, thats why it seems like they aren't lined up.
Yes you can relocate the vent fairly easily. Don't just eliminate it, though: in addition to venting sewer gas, they keep your drains flowing freely (think about pouring gas out of a can without the vent plug opened- it kinds of goes chug, chug, chug out of the can).
its a sewer stack pipe and code requires it .if you renovate it must be inplace somewhere in the dwelling and of equal size to the drain pipe itself .if it does not conform to local building code you must replace or repair it before you will be issued a certificate of occupancy.
It sounds like some sort of vent, so you could re pipe it as you rebuild and put it in a new wall, behind the linings.
As you will need plans and permits for what you want to do you will have to deal with some professionals, so ask them
Everyone is going in the right direction, but it is a vent pipe to allow water and wastes to go into the sewer line easily, other wise you would get a gurgling action like when you take a full bottle of liquid and dump it out all at once. If you were to put a hole in the bottle bottom it would flow freely. Sewer works the same way.
