Separate Vents. Sometimes, itâs just not feasible to vent only the sink, maybe because a shower or tub is sitting too far away, or maybe because one fixtureâs drainpipe does not connect to the main bathroom drainpipe, which is usually the line running from the commode. When this occurs, an additional vent is necessary. In new construction, the plumber will install a separate vent for any plumbing fixture that does not use the vanity vent. If a fixture has its own vent line, the line will run vertically to the attic and tie into the vent-and-soil stack if possible.
To allow equalization of air pressure throughout the waste plumbing system, we attach vent pipes to the tops of all the waste and drain lines and run them up through the roof. This allows air to escape up the vent pipes and through the roof. It also allows air to be drawn down the vent pipes from outside.Sewer gases can also escape up through the vent pipes. The venting system connects the waste piping system to the outdoor air, and lets air move into and out of the waste piping system as needed.t also allows air to be drawn down the vent pipes from outside.
