Anyone know what an air test is?

We are remodeling our kitchen and next year plan to install a new bathroom close to the kitchen. Since the ceiling is open above the kitchen, we are taking the opportunity now to pre-install the future bathroom venting and fan ductwork to run from the future bathroom area (now a hallway) up into the attic area above the kitchen and out the roof and side of the house. We are doing this so we do not have to break into the kitchen ceiling later on. Our plumbing inspector has said that we should do an "air test" so that we don't have to break into the kitchen area later. What is an air test and how do we do it? Thanks.

It is where the plumbing is sealed and slightly pressurized. It then sets for a period of time to verify there are no leaks.



These are the specs for the city of Toledo


AIR TEST: The air test shall be applied in the same manner as for water testing and as follows:

(1) Air testing apparatus may be attached to any suitable opening after closing all other openings in the section or system; (2) Force air into the system until there is a uniform gauge pressure of 5 pounds per square inch or sufficient pressure to balance a column of mercury 10 inches in height; (3) Maintain pressure without introduction of additional air for a period of 15 minutes.

FINAL TEST:

The final test of the plumbing system shall be made by air test after the fixtures are connected, with or without smoke or peppermint as follows: (1) Close stack openings; (2) Apply air pressure to entire drainage and vent system or to sections thereof equivalent to at least 1 inch water column; (3) Maintain this pressure starting 15 minutes before beginning inspection; (4) Test shall indicate system to be tight at all points.

The average home owner does not have the neccessary plugs and such to cap everything off. As far as I know, the inpsector needs to see the test but I'm not a plumber and could be wrong with that.
