I had a new counter installed. I switched from a drop in sink to an under the counter sink. The new sink lowered the garbage disposal approx 2 inches. The centerline of the drain on the garbage disposal is the same as the centerline on the horizontal stubs coming out of the wall which leaves standing water in the garbage disposal
The configuration is there are three horizonatal stubs coming out of the wall. The sink is a double sink. Each sink has its own P-trap and goes in the wall each in its own stub. Once inside the wall, the two drains come together in a four way (top for the vent, bottom for the drain, and left and right for each sink drain.)
A third horizontal stub comes out of the wall with a p-trap and then goes up about a foot where the dishwasher drain is inserted. Once this line goes in the wall, the drain ties in below the other four way and the vent ties in above the other four way.
the easiest one to lower a stub the two inches would be to move the dishwasher drain (the other two span a stud). Then to make the dishwasher drain for the garbage disposal and what was the garbage disposal drain make the dishwasher drain.
Is this acceptable? or does the dishwasher need its own drain line separate from the sink? In my previous house, the dishwasher just tapped into the garbage disposal. Location Pennsylvania
