Parts Desk Insights
Best Use Case: Best suited for boats that want automatic bilge control with the Ultima switch built into the pump assembly—use when you need reliable, frequent bilge water management and flexible hose sizing (1-1/8" or 1-1/4").
Common Issues: If the pump doesn’t cycle as expected, confirm the wiring to the pump switch circuit and check that the pump can freely run (clear any debris in the bilge area). Also verify hose connections and that the removable check valve is properly seated to avoid backflow or poor discharge.
