Johnson Pump 1000 GPH Multi-Port Shower Sump (12V) | 57151

The Johnson Pump 57151 is a high-capacity, all-in-one shower sump system designed to manage gray water from multiple onboard sources. Equipped with a powerful 1000 GPH Ultima bilge pump, this system efficiently collects and pumps water from showers, sinks, and tubs to a holding tank or overboard.

Compact and Clog-Resistant Design

This system is built around a rugged, pre-drilled collection box with multiple inlet ports of varying sizes, allowing you to connect several drains to a single unit. The clear, snap-on lid allows for easy visual inspection of the internal filter, while the integrated Ultima Switch uses patented Mirus field-effect sensing technology to activate the pump without moving parts that can jam or corrode.

Key Features:

• High-Volume 1000 GPH Pump: Equipped with a reliable Johnson Pump heavy-duty motor, providing rapid drainage even for high-flow shower heads.

• Multiple Inlet Ports: Features several "plug-and-play" inlet sizes to accommodate different hose diameters:

  • $1 \times$ 3/4" (19mm)

  • $1 \times$ 3/4" or 1" (19mm or 25mm)

  • $1 \times$ 1-1/8" or 1-1/2" (28mm or 38mm)

• Ultima Switch Technology: Uses a solid-state electronic switch (no float arm) that is not affected by hair, soap scum, or debris, ensuring reliable activation every time.

• Integrated Check Valve: Features a built-in check valve on the discharge port to prevent water from flowing back into the sump box once the pump shuts off.

• Removable Mesh Filter: Includes a fine-mesh primary filter to trap hair and debris, protecting the pump impeller and making maintenance simple.

• Clear Snap-Lock Lid: Transparent cover allows for a quick "at-a-glance" check of the sump status and provides easy, tool-free access for cleaning.

Why Choose the Johnson 1000 GPH Sump?

The 57151 is the preferred choice for boat builders and DIYers alike because of its "Multi-Port" flexibility. It eliminates the need for multiple thru-hull fittings and separate pumps for different sinks or showers. The 1000 GPH rating provides an extra margin of safety, ensuring the box doesn't overflow during simultaneous use of a shower and a galley sink.

Maintenance Tip:

To keep your sump system smelling fresh and operating at peak efficiency, pour a cup of fresh water and a small amount of biodegradable marine soap into your drain once a month. This helps break down soap scum and prevents "sump funk" in the collection box.
