Does my sink need an air gap?
Most plumbing codes stipulate that all commercial food and beverage preparation sinks must possess an air gap. States including California, Washington, Minnesota, and Hawaii have all adopted a dishwasher air gap installation as a mandatory residential plumbing procedure.
Why is there no air gap in my Kitchen Sink?
Bet you always wondered what that thing did (before you found out it floods your kitchen). “That thing” is actually called an air gap, and it prevents wastewater from siphoning back into the dishwasher, which can occur when sinks become clogged and no air gap is present.
Where is the air gap on a dishwasher?
The dishwasher air gap fits onto the top of your sink and should not normally do anything other than allow air into the dishwasher. When the dishwasher is running it’s possible for water to flow out of the air gap and onto the countertop.
Why is water overflowing into my sink when the dishwasher is on?
If so, it may have a clog that is causing the overflow. You can usually find the air gap at the top of the sink near the faucet. Ironically, the purpose of the air gap is to prevent dishwasher backflow. Therefore, if the air gap is not doing its job, there must be something in its way, obstructing it.
Why is water not flowing through my air gap?
Over time, food can clog an air gap, preventing water from flowing. Alternatively, when a new garbage disposal is installed, the installer forgets to remove a knockout plug from the input to which the water line is attached. Either of these situations is quite easy to fix, and below we’ll show you how.
