I am involved in a mild CONDO remodel (3 unit tall) and have a question about the kitchen sink water wall and DWV.
The main drain pipe is 2" vertical coming from the overhead unit and running along it is a 1 1/2" vertical vent. The kitchen sink drain is discharged through this combination via a horizontal 2" pipe. The vent comes into the horizontal drain via a sanitary tee. The tee was offset approx. 45 degrees from true vertical. This offset caused the width of the two vertical pipes to interfere with the drywall (too wide) and I re-plumbed the tee to a true vertical to reduce the spread of the two vertical drain-vent lines.
I now notice in my Harry Homeowner text that a Side Vent is a vent that connects to a horizontal drain pipe through a fitting no greater than 45 degrees to the vertical.
Does this imply a true vertical is not within code and that there has to be an offset? If the offset is necessary, can the vent be returned to the corrected path by fittings above the tee?
Any help is much appreciated.
