Question: 14-02 Code Section: 7 Date: 21 January 2014

OBC 2012 Reference: 7.5.2.1.

 

 

Question Submitted:

 

 

- I know table 7.5.8.1 states your only permitted 3 F.U. on a 2” wet vent But because the 3” stack is only 6” away would the W.C. not be stack vented as well?

 

- Could this installation pass?

 

Interpretation: NO. The WC is not stack vented as it is not the most downstream fixture as per 7.5.2.1(1)(d).

 

In addition, the total load on the branch connected to the WC trap arm is over 2 fu’s, as permitted by 7.5.2.1.(1) (f).
