I don’t see anything here that would cause siphoning or any other problem. What is your concern?
Mark,
Thanks, just the amount of turns.
Thanks, again.
The IRC and UPC do not allow a double trap (in series) but you can do a separate trap on each sink (in parallel - as shown) joined together in an appropriate wye to the wall.
Thanks! David
The UPC does not allow this installation. Only one trap is allowed on a trap-line. The UPC would require that the two sinks share one trap.
We do it in Wisconsin but with a clean-out between the two wyes.
What code does WI follow?
Ammended IBC
The irc allows 2traps to drain into a shared trap arm to the vent connection

The upc specifically prohibits this practice &all traps must enter the vent through individual trap arms.
