Bilge and Livewell Hose Installation Tips

• Match hose ID to the pump, thru-hull or plumbing fitting.
• Use the matching German-style hose clamp.
• Avoid sharp bends and kinks that can restrict flow.
• Keep discharge runs as short and direct as practical.
• Support longer hose runs to reduce sagging.
• Route hose where stored gear cannot crush or kink it.
• Inspect hose and fitting connections for leaks after installation.
• Protect electrical splices from moisture.

Why Hose Diameter Matters

The hose inside diameter should match the pump discharge or plumbing fitting. Using undersized hose can restrict water flow, while oversized hose may not seal correctly on the fitting.

For bilge pump installations, using the correct discharge hose helps the system move water as efficiently as the plumbing layout allows.
