Are S-Traps under a lavoratory sink neccessary?

The one I got does not line up under the pedestal sink
I can't see any drawbacks from leaving it out


All sinks must have a trap to prevent sewer gas from
escaping into the room.

Use a rubber flex section to make it line up
if you must.

"S" traps are no longer permitted, but if that's
the way this is set up you'll have to stick with it.
