Detailed description

Designed for managing grey water aboard recreational vessels, the Whale Manifold IC - 12 V system (WM8284) provides an automatic drainage solution. This complete kit features advanced technology to simplify the discharge of shower and sink wastewater, eliminating the need for bulky holding tanks and optimizing space onboard.

Intelligent Control (IC) technology

At the heart of this system lies Whale’s intelligent control (IC) technology, which enables sensor accessories to communicate directly with the Gulper® IC pump. This interaction ensures fully automatic operation: the pump activates only when water presence is detected and continues running for 15 seconds after the level drops for complete drainage. The Manifold IC manages two specific drainage points, offering an integrated solution for complex installations.

Performance and design

The WM8284 is specifically designed for grey water applications with an integrated bidirectional manifold. The Gulper® IC pump, the system’s core component, uses a large diaphragm and anti-clog valves to efficiently handle shower waste, including hair and soap, without requiring a filter, reducing maintenance. Its head can rotate 360° for installation flexibility. The system also features soft-start to protect the pump and extend its lifespan, and can run dry without damage.

Technical specifications and durability

Operating on 12 V d.c. (range 10 V d.c. to 13.6 V d.c.), the system delivers a high flow rate of up to 19 litres per minute (1140 litres per hour) with a 19 mm (¾") hose. The Manifold IC current draw is 0.01 A, with the Gulper® IC pump drawing 7.5 to 8 A. It achieves vertical self-priming up to 3 metres and a maximum discharge head of 3 metres, with a combined maximum of 4 metres. Inlet hose connections are compatible with ¾" (19 mm), 1" (25 mm), and 1½" (38 mm) diameters. Electrical connections use Deutsch® Quick Connect Series 7-way connectors. Constructed with a glass-reinforced nylon pump head, Santoprene® valves, and an aluminium pump body, the system is built for a marine environment. The circuit is fully encapsulated for water ingress protection. The system is CE-certified and meets ISO 10133, ISO 8846, IP45, ISO 8849, ISO 15083 standards, and carries a 3-year warranty.

Expert opinion

« Technical analysis of the Whale Manifold IC 12 V greywater system »

The Whale Manifold IC system – 12 V is a direct response to the space and complexity constraints of traditional gray water installations aboard. By eliminating the need for holding tanks or bilge sumps, it frees up valuable volume, particularly on sailboats and small motor yachts where every square centimeter counts. The integration of sensors and intelligent control logic simplifies use for the owner, who no longer needs to worry about manually activating the pump. This is a complete solution for managing shower and sink wastewater.

Whale’s "plug and play" approach with pre-wired Deutsch connectors significantly reduces installation time and complexity. The Gulper® IC pump head’s 360° swivel design allows easy adaptation to existing plumbing configurations. It is critical to follow mounting guidelines, including avoiding positioning below the waterline without a vent loop and mounting on a rigid surface (minimum 19mm thick) rather than directly on the hull.

The Manifold IC technology stands out for its ability to handle two drainage points simultaneously without manual intervention, an improvement over mechanical float systems. The Gulper® IC pump, known for its diaphragm and anti-clogging valves, prevents common issues like hair and soap residue clogging, extending maintenance intervals. The gradual startup and ability to run dry without damage are major advantages for equipment longevity, offering greater reliability compared to standard pumps.

It is imperative to note that this system is designed exclusively for gray water and must never be used for flammable liquids, fuels, or as a bilge pump in case of major flooding. Its purpose is comfort and daily management of shower and sink wastewater on recreational boats.

Frequently Asked Questions

Need help? Contact us

Is this system compatible with other Whale pumps?

The Whale® Gulper® IC Waste Pump Manifold IC WM8284 grey water system is an accessory in the Whale® Gulper® IC Waste Pump range. It is specifically designed for use with Whale Gulper IC grey water discharge pumps, which feature integrated intelligent control electronics.

How is the Manifold IC installed on a boat?

The IC Manifold is a key component of a high-capacity grey water drainage system. It is installed to collect water from multiple points (such as showers or sinks) before it is pumped outside or to a holding tank, typically in conjunction with a Whale Gulper IC pump. Typical installation involves connecting grey water inlets to the manifold and the manifold outlet to the pump or tank.

What is the Manifold IC Whale WM8284 grey water system?

The Whale WM8284 is a greywater management kit, specifically a "Grey IC" greywater kit with a two-way "Manifold IC" collector (manifold), operating at 12 V d.c. It is designed to be integrated into a greywater drainage system aboard recreational vessels.

What is the brand and model number of this product?

The brand of this product is Whale and its manufacturer reference is WM8284.

What is the required supply voltage for this system?

This Whale WM8284 IC Manifold greywater system is designed to operate on a 12 V DC power supply.

What is the purpose of the Manifold IC in this grey water system?

The IC two-way manifold collects greywater from multiple sources (e.g., two showers or sinks) and directs it to a discharge pump or holding tank. The "IC" designation indicates it is designed to work with intelligent control systems, such as those in the Whale Gulper IC pump range.
