Dishwasher air gap overflowing
The air gap for our dishwasher has been overflowing since we bought the house 20 years ago. It was an annoying problem but not serious. I tried to fix this problem several times. I replaced the hose, I replaced the air gap NO JOY. The air gap discharges into the garbage disposal. The disposal seems to drain freely. Now I think that part of the problem is height distance between the bottom of the air gap and the disposal is about a foot. The hose is about 20 inches long, and there is about12 inches of hose run that is has a minimal slope.
Question does the dishwasher have to discharge to the disposal? I live in Leland in Brunswick county North Carolina, does anyone know the local code? I tried the air gap into a bucket and it flows nicely.
