Side inlet quarter bend

[FLhome0wner]

Is it allowable in the Florida building code to use a side inlet quarter bend at the top of a vertical pipe? I plan to have a bathtub drain into the side 1 1/2", venting though the wet horizontal which will be 3" and serving a WC, lav and tub.

From your description, I don't think so unless it has its own vent.

The 3 inch horizontal will have it's own 3 inch vent about 4 ft from the 90 degree bend down. The tub going into the side inlet could have it's own vent, but why would it need it? Wouldn't the horizontal part of the quarter bend be able to wet vent that vent?

No, you cannot have the WC flushing past an unvented fixture.

Thanks for your response. As I understand it, a side inlet will work for this application if it is vented.
