Horizontal vent pipes okay?

In response to Horizontal vent pipes okay?
This is what Bob Vila has to say. Should I believe him? I could probably get 1/4" slope per foot instead of straight horizontal (it's only an 18" run if that). "Unlike drainpipes, vent pipes can run horizontally since gas-air pressure is drawn upward by the lower atmospheric pressure outside the house." http://www.bobvila.com/ArticleLibrary/Task/Building/DrainWasteVent.html Thanks! Mike : Can I have a flat section between where the takeoff starts and where it goes vertical? : So in other words off the takeoff install a 45 and then about an 18" flat section to another 45 heading upwards. Did that make sense? : If not I have other options just not as clean. : Thanks! : Mike : : : Reply: : : That looks like it will work. No flat venting. : : e-plumber
