    Is this an s-trap problem
    After p-trap, waste pipes goes level for 6 inches, then drops about 3 inches before going into walls, under bathroom sink. Is that a danger of s-trap siphoning if large volume goes down sink drain? Is this an S-trap? Or is it safe because of the level 6 inches of pipe?

    If the Ptrap doesn't connect into a vent then yes, you have an Strap there. To resolve this you could connect a mechanical vent (called an AAV.. air admittance valve) just after the Ptrap and that would fix the issue.
