SewerFlo RV Macerator Pump 12V 12 GPM Quick-Release Bayonet Mount — Portable, Self-Priming, Anti-Clog

Designed for RVers who need a reliable, fast way to empty waste holding tanks without permanent plumbing, this kit combines a self-priming macerator, quick-disconnect bayonet fitting, and a cigarette-lighter power lead for plug-and-play convenience. The four-spiral cutting blade system reduces solids to about 1/16" to minimize blockages, while the 12 GPM open flow and 10-foot lift let you transfer waste where gravity alone won't reach. Built for portability and straightforward use, it also includes a rinse feature and a manual anti-clog function for simple maintenance on the road.

How does the macerator prevent clogs and keep pumping smooth?

The SewerFlo uses a double set of spiral blades that rapidly chop solids into fine particles, significantly reducing the likelihood of clogs and improving flow consistency. Its self-priming design means the pump draws fluid on startup without complicated priming steps.

• Four spiral cutting blades grind waste down to ~1/16" particles.
• High-speed maceration reduces clogs by up to 95% compared to unprocessed flow.
• Self-priming action allows immediate operation after hookup.
• Manual anti-clog blending restores flow if debris accumulates.

Can I use this pump with standard RV sewer outlets and hoses?

Yes — the pump features a standard 3" (75mm) bayonet RV connector for fast attachment to common dump points and a 1" hose barb for discharge. The quick-connect design makes setup and removal fast, so you can swap locations without tools.

• 3" bayonet RV connector compatible with most RV dump fittings.
• 1" hose barb accepts flexible discharge hose for longer runs.
• Quick-cut bayonet locks securely to prevent leaks during pumping.
• Compact unit stows easily when not in use.

How powerful and far can it pump — is it suitable for long-distance dumping?

The SewerFlo delivers an open flow of about 12 gallons per minute and can lift waste vertically up to 10 feet, giving you the reach to move wastewater where direct gravity dumping is not possible. The combination of maceration and flow rating keeps the pump effective even with longer discharge lines.

• 12 GPM (≈45 LPM) open flow rate for rapid emptying.
• 10-foot maximum vertical lift for uphill or distant dump points.
• Consistent flow when paired with proper hose diameter and routing.
• Impeller materials (rubber and copper) balance durability and performance.

How do I power and maintain the pump when traveling?

Power is provided by a 12V cigarette-lighter plug and quick-disconnect wiring, so no permanent wiring is required — ideal for portable use across rigs. Routine care is simple: run the built-in rinse system after use and use the manual anti-clog option if required.

• 12V cigarette-lighter plug for tool-free power hookup.
• Quick-disconnect electrical connectors for fast setup and stowage.
• Built-in fresh water rinse port to flush debris after use.
• Manual anti-clog blend function to clear stubborn blockages.

Who is this for? The SewerFlo Quick Release 12V Macerator Pump is aimed at RV owners, boondockers, and campervan travelers who need a portable, reliable method to empty black and grey tanks without installing a permanent pump. It’s especially useful when campsite dump stations are distant or when you prefer a fast, plug-in solution that minimizes clogs and storage footprint. If you need straightforward operation, quick hookups, and a pump that handles both short and longer discharge runs, this kit is built for that use.
