There can be turns in the drain, but every inch of the vent must rise vertically until it meets the minimum height. Sometimes the drain will need to be routed to an entirely different location to make the vent work.

Significant portions of the vent may have to be installed below the flood-level rim of the fixture. For example, there may be an installation of a floor drain where the distance from a wall that might be used to place the drain's vent exceeds the trap arm distance. In this installation the vent would have to be placed in a horizontal position until it could turn vertically in the wall.

This vent, until it rises 6 inches above the overflow rim of the fixture, is in fact a drain. If there is a overflow condition, the vent would be filled to the rim of the fixture. When the stoppage is cleared, the waste in the vent has to flow to the drain and it must do so using drainage fittings. The horizontal portion of the vent must also be graded back to the drain to allow the overflow effluent to recede.
