I am just replacing an old double bowl sink at a rental unit . I put a new granite countertop in and now have a single bowl coming down the bottom . The sink and pipe going to the ground is just about directly underneath each other maybe a half inch off .
I'm having a real hard time fitting the swivel on with the P-trap . No matter how close I push it is just not enough to get there . I did read that we can use a rubber coupling and maybe have that work ?
Is there a joint under that escutcheon?
If so, why not run an elbow toward the back wall, then an elbow upward to a vertical pipe, then an elbow forward to a conventional p-trap?
This would effectively reduce the risk of siphoning water that an s-trap creates.
If there is not enough distance in back of the pipe, the whole elbow/p-trap thing could be canted to one side or the other.
One or more joints could be eliminated if you can find a run of pipe with an integrated elbow. The lower horizontal run is needed only if the elbows don't move the vertical pipe far enough back to accommodate the p-trap.
