Why is water draining out of air gap when using dishwasher?
We have installed new hoses and air gap venting (mounted on rt. of sink) and ck'd garbage disposal plug etc.. trying to eliminate water draining from the vent. I have to place a few towels around the vent to soak up the water that drains out during the dishwashing cycle.
There is no back-up in the sink and our home is about 4 yrs. old. No smells from the sink, just lots of water coming out the vent!
