Installing utility sink next to washer/dryer

I know this topic has been covered extensively, not only here but all over the web. The problem is that there is so much conflicting information out there. I have gathered the following from what I have read. 1) It seems that if I want to do this by code, I can not just tap into the washer stand pipe, even though it has a trap and a vent. Also I have read that I may be able to meet code as long as I don't put a trap on the sink since this would create a double trap situation. I have enclosed 3 pics of my situation. It is a 5 year-old house and the laundry area is in the basement as seen in the photos. The first pic shows the drain stack (vertical 5") on the left, the vent stack (Vertical 2")in the center and the washer stand pipe to the right. The second pic shows the sink where it will sit and the third pic shows the view from the sink drain point toward where it would need to connect. What is the best way to add a drain for my utility sink?

*UPDATE* A very helpful person has given me a solution for my problem, thanks!

I am not sure but I think you can tie into the vent with a trap. It would be a wet vent. I am sure you will get some responses now to correct me if I am wrong.


I may go home hungry, but not tired and hungry.
