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.
Dishwasher Venting Problems. Dishwasher venting problems are usually caused by a clogged vent or drain mechanism. As the dishwasher runs, water flows into the unit through the water supply and back out through the drain. To prevent the water from siphoning out of the unit during the washing cycle, air is vented from the dishwasher as water drains.
