Yes--I have the disposal plumed into the left sink. The disposal drain crosses over to drain the right sink. The dishwasher drain is attached to a vacume breaker above the right sink and drains into the right sink drain before the "P" trap.
Larry--I got to thinking about the vacuum breaker and took it apart and found a plug. It works as new now. Thank you for your time and please keep the fee. I just knew it was simple, just wish I would have thought of it before buying parts.
