   Can't be fixed connections.  That's why the discharge hose is candy-cane shaped and fit down into a larger drain pipe.  Prevents reverse suction of the discharge.

   Well there's two things that a lot of people & plumbers just starting out get confused with.

   Air gap verses an Air break.

   Air break---- A physical seperation which may be a low inlet into the indirect waste receptor from the fixture, appliance, or device indirectly connected.

   Air gap---- The unobstructed vertical distance through the free atmoshere between the lowest opening from any pipe. plumbing fixture. appliance, or appurtenance conveying waste to the flood level rim of the receptor.

   So an example of an air gap would be where the sink faucet is higher than the rim of the sink, right?  Then what's an example of an air break?"Put your creed in your deed."   Emerson

   Like you said a clothes washer discharge hose into the standpipe.

   The mislabled dish washer "airgap" on top of a sink.
