Parts Desk Insights
Best Use Case: Ideal when you need automatic bilge pumping in a low-clearance compartment. The swiveling discharge and included straight/90° connection help you match the discharge direction to your existing plumbing layout.
Common Issues: If you’re getting intermittent cycling, confirm the discharge line is properly routed and free of kinks/obstructions, and verify any check valve/backflow setup aligns with your chosen straight-fitting installation. During install and service, ensure the discharge adapters match your hose size (3/4", 1", or 1-1/8") and that mating connections are snug and leak-free.
