Parts Desk Insights

Best Use Case: A practical choice for boaters who want a simple, mechanical-style automatic bilge pump control that responds to actual bilge water levels while adding false-start protection.

Common Issues: If the pump cycles too frequently, confirm the switchs mounting position and water-level measurement point, and inspect for debris or obstructions around the switch area even though the design is non-clogging. For wiring-related symptoms, verify correct lead terminations and secure connections along the 6′ wire run.
