Plumbing Vent Layout
A clear plumbing vent layout is essential for any multi-story building. With ArcSite, you can easily design and document how vent stacks and soil stacks support multiple bathroom fixtures—ensuring your systems are fully functional and up to code.
Key Considerations When Planning Your Vent Layout
A proper vent layout ensures fixture traps don’t siphon and sewer gases stay out of the building. Follow local code for vent pipe sizing, spacing, and termination above the roofline. Grouping fixtures on vertical stacks can simplify design and save material. Be sure to place cleanouts for maintenance, and keep vents away from windows or air intakes for safety.
What’s the difference between back venting and stack venting?
Back venting (continuous venting) uses a separate line to vent a fixture, while stack venting combines venting and draining in the same vertical stack. Shown is an example of back venting.
