Floating strainers can draft water from sources as shallow as how many inches in depth?

• A. 12 inches
• B. 18 inches
• C. 24 inches
• D. 36 inches

Answer: (C)

Floating strainers are designed to pick up water from near the surface while staying submerged enough to keep air out of the suction line. They can draft water from sources as shallow as 24 inches. This minimum depth keeps the intake below the surface far enough to prevent air entrainment and surface turbulence from breaking prime. If the source is shallower than 24 inches, air can enter the line and the pump may lose prime or cavitate. The other depths aren’t the reliable minimum in this context: 12 and 18 inches are too shallow to stay consistently submerged, while 36 inches is deeper than needed for the minimum draft capability.
