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.
The air vent pipe is clogged. A sewer tape ran down the air vent line (usually on the roof) may unclog the line. 3. The vent line system is to far away from you toilet and is improperly located. If the gurgle is under a sink (kitchen or bathroom) they make a vent that can be installed under the sink. This vent has a baffle to prohibit sewer gas from coming into your house. The baffle opens to allow air into the drain line to release the vacuum.
