Kitchen Waste piping question

For my clarification and knowledge. Is the attached photo considered an S- Trap.
This is on a kitchen sink (Not an Island sink). No venting visible.

I agree…

That is an S trap. Do a search on the InterNachi web site for P traps and S traps. You will find a wealth of information and look also at kitchen sink drain connections for the proper way to connect the two sinks into one drain line. Good luck


Did you look at the risers to see if they were PB?
