Crown-Vented Laundry Drain Trap?

Hi All....great forum! I hope I'm not embarrassing myself by asking but does this laundry drain constitute an improper crown-vented trap or any other defective drain/trap? Thanks!

Yes the stand pipe must not have any off sets.

NO. It is done like that anytime there is not room in the stud space for the trap and wall box to fit with a straight riser. How else COULD you do it? A box with the outlet offset to the side would help, but they are not that easy to locate. Don't sweat it.

You need twice the pipe diameter between the trap elbow and the sanitary tee inlet.

I would say he has about that much center to center, and I have never had an inspector turn down an installation like this one. What do you want him to do, remodel the wall to give more room between the brick and the stud?

The measurement is taken from the crown weir to the opening in the tee. In that situation the inspector is likely to overlook it.

It's an S trap. Every inspector in a 200 mile radius of here would make him change it. You do what needs to be done to meet code.
