It is common for modern DWV systems to be tested with air. In the old days water was the most common means of testing.

When there is a leak that cannot be found easily, smoke can be used to expose the leak location. Smoke is not used as a primary test method. Air is the test medium of choice. The testing of a DWV system is to be conducted for a minimum of 15 minutes. The minimum test pressure is required to be 10 pounds per square inch (PSI). If only underground plumbing is being tested there must be one riser that is at least ten feet above the main plumbing system. The maximum allowable time for the retention of gray water that will be used to flush toilets or urinals is 72 hours.

Holding water for long periods of time can result in the growth of bacteria. This bacteria is not wanted in the plumbing system. For example, green water in a toilet tank is not appealing and could present health hazards. When a gray water recycling system is sized properly the water retained in a collection reservoir would be balanced to the fixtures served and the normal daily use of the fixtures will draw down from the reservoir often enough to avoid prolonged water storage.
