Whale Grey IC Automatic Grey Water Waste Pump System – 24V | MPN: WM8484

Simplify your boat’s grey water plumbing with the Whale Grey IC Automatic Grey Water Waste Pump System – 24V (Part Number: WM8484). Combining Whale’s renowned Gulper IC non-clog diaphragm pump with an intelligent two-way sensing manifold, the WM8484 automatically drains grey water from up to two separate shower, sink, or galley outlets through a single discharge pump.

By utilizing Whale Intelligent Control (IC®) solid-state sensors built directly into the manifold wall, the system detects water presence without mechanical float switches, sumps, or filter mesh screens that accumulate hair, soap scum, and debris. As soon as grey water enters the manifold, an electrical signal triggers the 24V Gulper IC pump to evacuate the water at up to 5 GPM (19 L/min), automatically turning off when the lines are clear.

Key Features & Performance Advantages

  • Automatic Intelligent Control (IC®): Two-way manifold senses water level through non-contact wall sensors, eliminating messy, clogged shower sumps and sticking float switches.

  • Non-Clog Gulper IC Diaphragm Pump: Easily passes hair, lint, and food particles without clogging or requiring inline filter mesh cleaning.

  • Multi-Drain Consolidation: Accepts two separate grey water inputs into one compact manifold, enabling a single pump to service two showers or a shower and sink combination.

  • Self-Priming & Dry-Run Safe: Gulper diaphragm design can self-prime up to 10 feet (3 m) and run dry without motor damage.

  • Integrated 24V Wiring Lead: Ships pre-wired with a 13 ft (4 m) heavy-duty communication cable connecting the manifold directly to the pump logic harness.

  • Multi-Size Stepped Hose Ports: Includes flexible hose connections supporting both 3/4" (19 mm) and 1" (25 mm) inner diameter marine sanitation hoses.

Frequently Asked Questions (FAQ)

Q: Do I need to install an inline filter mesh or strainer before the pump?

A: No! The Gulper IC uses a valve-free diaphragm mechanism specifically designed to pass hair, soap scum, and small debris without clogging or requiring inline strainers.

Q: How does the system know when to turn on if there is no float switch?

A: The Intelligent Control manifold uses solid-state electronic sensors embedded inside the manifold body that detect the electrical capacitance of water contacting the internal wall, automatically triggering the pump relay.

Q: Can I connect both 3/4" and 1" hoses to this manifold?

A: Yes, the manifold ports and pump fittings feature cut-to-length stepped hose barbs that accept either 3/4" (19 mm) or 1" (25 mm) smooth-bore sanitation hose.
