Questions & Answers

Is this a genuine original part?

This is a genuine SEAFLO 02-Series product. SEAFLO is a leading global manufacturer of marine and RV pump systems, known for high-quality engineering and reliability.

How do I know if it is compatible?

This switch is universal and will work with any non-automatic (manual) bilge pump that draws up to 18A. Check your pump's amp rating to ensure it is below the 18A threshold.

At what water level does the pump turn on?

The SFBS-18-02 is calibrated to turn the pump ON when water levels reach 60mm (2.36") and turn the pump OFF when the level recedes to 30mm (1.18").

Note: Please ensure all wire connections are kept above the water line and sealed with marine-grade heat shrink for safety. Visit 4boats.co.uk for more marine plumbing accessories.
