Parts Desk Insights

Best Use Case: Ideal for replacing a bilge pump setup when you want an automatic electronic switch operation combined with the cartridge-style pump and included discharge components.

Common Issues: If the pump cycles unexpectedly or wont start, confirm the switch orientation/clearance in the bilge and inspect hoses and hose clamps for proper installation (avoid over-tightening at the discharge port). Also check that the removable check valve and discharge path are not obstructed.
