I work 8-5, so yes, I realize apple is open during these hours. I know they are open until roughly 6 or 7pm. It's the after 5pm hours, and sat/sun hours I'm interested in. So I can plan my week.
An air gap for a dishwasher is a requirement set forth by local plumbing codes. It is a device designed to ensure water flows only in the right direction during the dishwasher cycle. As a dishwasher operates, hot water flows in from the sink's hot water connection.
AIR GAP The simplest way to prevent a backflow from occurring is to install an airgap. Refer to Figure 22-5. Air gaps should be twice the diameter of the pipeand not less than 1 inch. An air gap is the unobstructed vertical spacebetween the water supply and the flood rim of the receptacle.
