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.
Note: Some stoves (Ekol 5 and 8 for example) CANNOT be swept through the stove so you will need to have a sweep-door in the pipe between the stove and the closure plate (in an elbow or in a straight section of steel vitreous pipe). Also see: Air gap above stove. This black steel vitreous flue does not have an offset. The pipe is passing through a sealing plate (available from our store). Note the A1-fire-rated Hardiebacker lining board within the recess.
