Amarine Made 12V 750 GPH marine shower sump pump system — compact self‑contained unit with clear lid & removable mesh filter

This compact, all-in-one unit combines a pump, float switch and filter inside a sealed box designed for boats, RVs, or small off-grid installations where collecting and pumping greywater or shower waste is needed. The system ships ready to mount and connects to standard 12V power; its clear cover and removable mesh screen simplify maintenance while a built-in check valve prevents backflow.

How does the Amarine Made sump pump manage shower and sink waste?

The unit channels greywater into an internal chamber where the integrated float switch activates the 750 GPH pump when liquid reaches operating level. A slot-in mesh screen captures hair and debris before it reaches the impeller, reducing clogs and protecting the pump.

• Built-in float switch for automatic on/off operation.
• Removable mesh filter traps hair and solids for easy cleaning.
• Check valve on outlet prevents backflow into the chamber.
• Clear lid allows visual inspection without opening the box.

What are the installation steps and required connections?

Installation is straightforward: position the box, cut hoses to proper length, attach flexible hoses to the outlet, clamp lightly, and wire the pump to a 12V circuit with appropriate fuse. Multiple inlet ports make it simple to route waste from more than one fitting into the sump chamber.

• Cut hoses to fit; avoid over-tightening clamps to prevent breakage.
• Wire to a fused 12V supply and ignition-protected circuit where applicable.
• Use included check valve and secure hose fittings to stop leaks.
• Mount on stable, level surface with accessible lid for service.

What maintenance does the system need to stay reliable?

Routine maintenance is minimal: periodically remove the clear lid, lift out and rinse the mesh screen, and inspect the check valve and outlet hose for blockages or wear. Keeping the lid tight reduces splashing and odors and helps the unit operate hygienically between services.

• Rinse or replace the mesh filter at regular intervals.
• Inspect the check valve and hoses for cracks or deposits.
• Tighten lid to minimize splashes and odors after inspection.
• Test float switch operation occasionally to ensure activation.

What performance and safety features should I expect?

The 12V 750 GPH pump delivers strong flow for short runs and gravity-assisted discharge; the integrated check valve and ignition-protected design add safety when installed on vessels. The unit handles wastewater from multiple sources and is built for compact marine and mobile environments.

• 750 gallons per hour pumping capacity at 12V supply.
• Ignition-protected motor suitable for marine installations.
• Tight-fitting lid and sealed housing reduce splash and odors.
• Multiple inlet ports accept plumbing from several fixtures.

Who is this for? The Amarine Made 12V 750 GPH Shower Sump Pump System is intended for boat owners, RV enthusiasts, tiny-home builders, and anyone needing a compact, reliable greywater collection and pump solution. It suits installations where space is limited, plumbing must serve multiple fixtures, and simple serviceability and automatic operation are priorities.
