I have a double sink. Left side has a garbage disposal and the right side does not. The left side has a trap then drains to the right side which then has a trap too.
Once in a while when I run the garbage disposal it vibrates and shakes and some fitting will come loose and water splashes everywhere. I had this happened twice in the last three months.
So, I think this is because the whole contraption (done by last owner) has too many fittings. I counted nine.
Is the picture below the way it should be hooked up? I kind of think may be the trap between the garbage disposal and right drain is not needed. Any advise?
