Correct wiring prevents nuisance tripping and ensures bilge pumps run when needed. SEAFLO automatic pumps simplify wiring by integrating the float switch.
Circuit Basics
Run a dedicated fused circuit from the battery or breaker panel. Do not share a fuse with navigation electronics.
3-Way Panel Wiring
Wire the Auto-Off-Manual panel between battery and pump. Auto connects through the float; Manual bypasses for testing.
Built-In Float Switches
06 Series automatic pumps include internal floats — you can wire direct with an inline fuse if you skip a panel, but a panel adds manual test capability.
Common Mistakes
Undersized wire causes voltage drop and slow pumping. Missing vented loop on discharge above waterline can siphon water back into the bilge.
