When we run the dishwasher, there is no water escaping from the air gap. If we fill both sides of the double sink, then water escapes the air gap every time the dishwasher drains. The amount of water escaping is not insignificant.
Note 1: the dishwasher drains into the disposal after leaving the air gap.
Note 2: most times when starting the disposal, some water is forced into the other sink then drains.
Things I have done already:
- verified that the drain is clear of obstructions
- verified that the vent to the roof is clear of obstructions
- verified that the disposal drains properly
I am no expert, but my gut tells me the problem is lack of air flow. I assume that would lead me back to the roof.
Any help will be most appreciated.
