Branched vents usually have a diameter of 2, one-half-inch, and one-fourth-inch. These vents can be installed horizontally or vertically, depending on the requirements of your plumbing code. You can also choose to install branching vents horizontally, but some codes require a sloped vent to direct water away from the drain. Also, you need to keep in mind that the point of connection of each fixture must be at least six inches above the flood level. Additionally, the point should not be too far away from the P-trap, which will depend on the diameter of the vent pipe.

If you need to install plumbing vent pipes in residential spaces, a 1.5-inch diameter pipe is usually sufficient. However, some plumbing codes require a larger vent pipe for larger building drains.
