Parts Desk Insights
Best Use Case: A strong choice when you want an automatic bilge pump setup that’s designed to be serviced through cartridge replacement, with straight and 90° Dura-Port discharge options for cleaner routing.
Common Issues: If performance drops, inspect the discharge connection and check valve function, and confirm the hose routing/clamping doesn’t stress the Dura-Port. For intermittent cycling, verify float/switch wiring and clean any debris from the bilge area so the switch can operate normally.
