Dishwasher Blockage Standing water indicates that your dishwasher isn’t draining correctly. Check the drain in your dishwasher, as well as the drain hose, for any obstructions. You should also be mindful of the amount of dishwashing detergent you use; over time, residue can build up and cause a clog.

Where is kitchen sink air gap?

A dishwasher air gap is a small, egg-sized item that connects your dishwasher to the kitchen sink drain. It’s usually mounted above the sink near your faucet. This device can prevent contaminated water from draining back into the dishwasher.

Why does a sink need an air gap?

This gap is usually about the distance between the faucet and the top of the sink or bathtub (one inch or more). Basically, the air gap is there to prevent accidental backflow. If contaminated water backflows, it can cause serious health risks. Without the air gap, wastewater could siphon back into the drinking supply.

Should any water come out of air gap?





Water coming out the air gap should not be a regular occurrence, though occasionally it might happen when, for example, someone forgets to run the garbage disposal. Regular water discharge from an air gap points to a restriction in the water flow.
