Forum Title: toilet drain : 90 deg bend vs. 2x45 deg bend
Hi, Trying to set up new drain for toilet. Going to do a branch from main using a combination wye (horizontal) and then turn up to the flange where the toilet is. My question is, does it drain better to split into 2 x 45 deg bends vs. a 90 deg long turn elbow where it goes up to meet the toilet flange (see layout)? Thx

The main stack (2 vent) is about 2 feet away. I've updated the picture in the original post to include the main stack. A quick question: the max distance from a drain to the nearest vent needs to be within 5 feet. Does that refer to the actual horizontal run thru' the piping (in this case, it'd be 2 feet down to where the branch meets the main, and then back almost 4 feet to where the main goes up the main stack -- that would be 6 feet total run), OR the direct horizontal distance between the drain location and the vent (drawing a horizontal straight line from the flange to the main stack) which would be roughly a little over 2 feet then)? Update: A plumber just told me that 5 ft limit was for P-trap. Not for toilet drain.
