      Check that the rubber “O” ring that forms the seal is still intact and has not been kinked or crushed out of shape preventing the seal being made water tight.
      Do not overtighten the plastic locking nut as you can crack the base of it and also cause a leak.
      Also check that there is no grit or rubbish stuck anywhere on the large rubber seal washer that slides up and down the pipe itself and is sealed with the locking nut.
      If the leak is above the plastic pipe where it fits onto the sink outlet waste then it is likely that the sink waste is not sealed into the sink properly – remove same and apply a bead of silocane sealant to the underside of the sink waste recess in the sink then refit the waste outlet and tighten up sufficiently to squeeze out surplus sealant.

      undo the top nut, then undo the bottom nut. Slide the trap up the pipe until there is no gap at the top. Then do up all the nuts and the problem is fixed.

      The vibration of my garbage disposal causes one of the joints to come undone. I have to periodically grab the pvc “nut” and twist it clockwise till I feel resistance and then STOP twisting.

      That piece that slips when disposal is running take nut loose get some PVC glue and cleaner and glue in a couple of spots and let dry and put nut back, should help.
