What is an Air gap and do I need one?
An “Air gap” is like a little two inch metal cap that sits at the top of your sink. This is supposed to prevent dirty water from backwashing back into your dishwasher. However, newer dishwashers and sinks with garbage disposals make it possible to eliminate this extra little metal cap. Consult your plumber and see, if you can run your dishwasher safely without having an “Air gap”.
