A seep falls under Class B when its size is between which inches?

• A. 1/4-3/4 inches
• B. 1/8-1/4 inches
• C. 1/2-1 inches
• D. 1-2 inches

Answer: (A)

In maintenance practice, leaks are categorized by size to decide what repair action is needed. A seepage within 1/4 to 3/4 inch is classified as Class B because it represents a moderate leak—larger than a minor seep but not large enough to be considered a critical fault. This sizing helps technicians choose an appropriate repair approach, such as resealing or replacing a small component, rather than a full system overhaul. Smaller seepage (under 1/4 inch) is typically Class A and may require only monitoring or minor work, while larger leaks (over 3/4 inch) become Class C and usually trigger more extensive repairs or system shutdowns.
