Connect Drain Lines

With the disposal in place, the next step is to connect the drain lines as follows:
  • Fasten the discharge tube to the disposal unit with its gasket and screws.
  • Now properly position the disposal by turning it so that the discharge tube aligns with your waste trap.
  • You may need to add extension pieces or cut pipe to make the proper connections.
  • It is important that these connections be well made and tight.
  • Once the drain connection is made, connect the dishwasher line if used.
