Question 1

Which of the following is suitable for testing a DWV system for leaks?

Accepted Answer

All of the above

Answer

Explanation:
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.
