Vertical drop in horizontal branch

Hi, is this allowed? This goes to a sanitee that serves the kitchen sink and then continues through the roof as a vent.

Presuming the flow is right to left, what you show is fine.

Just out of the picture, the 90 that transitions from vertical to horizontal should be a long sweep. That is the place where drain lines under a kitchen tend to clog.

Thanks and thanks for that extra caution about the long sweep.

However, the fitting on the left that is out of view was described as a San Tee. The San Tee can only be used as a drainage fitting if the brand is the vertical and the trunk is vertical. It can not be used as a drainage fitting if it is horizontal throughout or vertical to horizontal.

Only if you interpret "goes to" as downstream. In the OP "goes to" means upstream, since it then "continues through the roof as a vent."

True. So the downstream fixture should be a drainage fitting.
