Does "Air Gap" refer to the space under a Bungee Jumper?

       While it is most likely an excellent idea for the Bungee Jumper to have a proper Air Gap----that is not the kind of air gap I am talking about here.  I am sure most of you recognize the little chrome shape cap located on the back of your Kitchen sink----or sometimes located on the countertop.  This "thingy" is called an Air Gap Device and assists in proper drainage of the dishwasher.  Most jurisdictions require them nowadays.  Water coming out of the cap during operation of the washer is signaling a plugged drain----and cleaning is necessary.

Air Gap Device 

     But this post is not about the device on top of the countertop.  It is about the part of the device "under" the countertop.  Because of its location, behind the sink, access and installation become difficult.  The hoses from the washer to the air gap device, and from the device to the drain connection, should be properly connected with hose clamps.  When the connections are not properly connected they can work their way off the device resulting in a flooding mess in the sink cabinet.

     It is a good idea for the home inspector to check these connections to make sure they are in place.  In this picture we see the "camera-eye" view of the device attached to the underside of the countertop.  Can you see that the black hose is barely holding onto the turquoise colored air-gap device?

     In this next picture we can see the hose clamps stacked on top of each other at the drain connection.  Can you see the stains from past leaks?

Hose clamps out of place 

     As a side note, there is another issue here that is totally unrelated to the Air Gap Device.  The connection of the black ABS plastic pipe to the white PVC plastic connector is not allowed in most jurisdictions.  I know in my own area that, even though there are adhesives that claim to be satisfactory for both types of pipes, it is still not allowed, and regardless, the black adhesive used on this installation is NOT the correct adhesive.  I guess the thinking is that the jurisdictional inspectors don't want to be in the business of determining if the proper adhesives were used.
