Which statement best describes bilge hose construction and sizing?

• A. They must be lightweight and flexible with no reinforcement
• B. Heavy duty reinforced; must match the diameter of the pump output
• C. Made of copper and non-flexible
• D. Only used for fuel

Answer: (B)

Bilge hose needs to handle the rough environment of the bilge and maintain a reliable flow from the pump. That means using a heavy‑duty reinforced hose that can resist kinking, abrasion, and pressure, and it must match the pump’s discharge diameter so the connection is secure and flow is unobstructed. If the hose is lightweight or unreinforced, it can collapse under suction or wear out quickly, leading to leaks or loss of pumping capability. Copper or non‑flexible hoses aren’t typical for bilge discharge because they’re hard to route and don’t endure the vibrations and bends in a boat. Hoses used only for fuel are inappropriate for bilge water and pose safety and contamination risks.
