| Question: 09-03 | Code Section: 7 | Date: 14 February 2009 | OBC 2006 Reference: 7.5.1.1.(3), 7.5.2.1, 7.5.8.1. |
Question: Is this illustration acceptable to code?
Interpretation:
1. Permitted – the floor drain served by the Laundry Tub. 7.5.8.1 determines the minimum sizes wet vents, so the 4″ extending above grade with a cleanout where the wet vent continues is permitted although connected to the vertical section by a TY to serve the Laundry Tub’s continuous vent.
2. Not-Permitted 7.5.2.1(h)(i). – the floor drain served by the Kitchen Sink has a double offset. Change the Ty to a Wye and 450 to correct. Also a Cleanout is required.
3. Permitted – the floor drain connected to the branch downstream of the 3-inch stack.
Drain Interpretation: Approved at AMES 2009
