Plumbing Vent Layout
Good venting is why a toilet flushes with a clean pull and a sink drains without gurgling, and nobody notices it until it's done wrong. Every fixture on two floors ties into one stack through the roof in ArcSite's plumbing vent layout.
Key Features
This plumbing vent layout includes:
- Two-story section view up through the roof
- 3" soil stack from the building drain to the roof
- 2" vent stack running beside the soil stack
- 1-1/2" vents serving the upper-floor fixtures
- Toilet and lavatory on the lower floor
- Toilet, lavatory, and a second sink on the upper floor
- Building drain sloping out below the first floor
- Color-coded legend for each pipe size
The 2" vent stack reconnects to the soil stack above the upper floor, so both floors share one roof penetration instead of two.

Frequently asked questions
Does this layout show the supply lines?
No. It covers drain, waste, and vent piping only. Draw the hot and cold supply runs in ArcSite if the job needs them on paper too.
Can I change the pipe sizes in the legend?
Yes! You can edit each pipe's color and size label in ArcSite to match the stack you're installing.
Can my office staff open this drawing without a paid seat?
Web-only users are free, so the office can view the layout while paid seats stay with the people drawing in the field.
