It’s my understanding that a dishwasher air gap is supposed to prevent raw sewage from backing up into dishwasher and if the drain becomes clogged, the air gap is supposed to will discharge the dishwasher water into the sink. Because water has been discharging out of my dishwasher’s air gap, I replaced the air gap yesterday. However, now water is leaking down into cabinet because the sink hole is slightly bigger than the top air gap mounting nut and water is stilling being discharged through the air gap itself. I’m not sure what else I can do because water is flowing to the disposal and through the air gap itself.
Does anyone know why my dishwasher is still discharging water through the air gap?
