Which issue is most likely to cause an air test failure in a new pipe?

• A. Sagging pipe
• B. Pipe too short
• C. Rubber ends blocking pipes failed
• D. Could cause the air test to fail

Answer: (B)

Air tests check that a sealed run of pipe can hold a specific pressure long enough to show no leaks. If the pipe segment is too short, the amount of air inside the line is smaller, so any leakage causes a faster drop in pressure. That means even small leaks or imperfect seals will bring the pressure down below the test threshold quickly, causing the test to fail. In short, insufficient air volume in a too-short segment makes leaks easier to detect and the test harder to pass.
