S trap in kitchen island

Hi I notice an S-trap underneath the kitchen island sink . Would this be a red flag ? Thanks

They all are.

Hmm, yes. Check for proper venting as well since its an island

All S traps can be an issue. That one is an easy fix, just take the right side out and it’s a straight shot over the the T.

Island venting is an issue as well. There is probably an AAV under there.

Not a red flag, just a common issue. Report as such.
