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
