Kitvance 12V RV Macerator Pump Kit — Portable 12 GPM Sewage Macerator with Copper Motor and 3" Inlet

Kitvance 12V RV Portable Macerator Pump Kit is a ready-to-use, self-priming sewage pump that grinds waste and moves up to 12 gallons per minute for fast, clog-resistant holding tank emptying.

If you need a compact, reliable solution to empty RV waste tanks without hauling hoses or relying on campground hookups, this complete macerator kit is built for that job. It connects to a standard 3" RV waste outlet and runs on 12V DC, combining a high-torque macerating rotor with a copper motor to cut solids, protect against blockages, and deliver steady flow for convenient disposal.

How quickly and effectively will this pump empty my RV tank?

The Kitvance macerator moves up to 12 GPM and can empty a standard 150-liter sewage tank in roughly five minutes under ideal conditions. Its dual 4-spiral blades reduce particle size to about 1/16", minimizing clogs and allowing smoother passage through discharge lines.

• Flow capacity: 12 gallons per minute for rapid emptying.
• Particle reduction: blades macerate solids down to 1/16 inch.
• Recommended lift: 10 feet maximum discharge lift for uphill waste transfer.
• Self-priming suction: up to 3.2 feet for short draw operations.

What connections and power options are included for out-of-the-box use?

This kit arrives ready to install with all required fittings sized for typical RV waste ports: a 3" water inlet and 1" outlet. Power options include a 7-foot cigarette-lighter adapter for quick hookup and an 11.4" alligator-clip cable for battery connections, so you can run it from your RV battery or vehicle accessory port.

• Water inlet: 3" standard RV waste connection.
• Water outlet: 1" discharge port compatible with common hoses.
• Dual power cables: cigarette-lighter and alligator-clip adapters included.
• Operates on 12V DC and draws approximately 12 A under load.

Is the pump durable and safe for repeated use?

Durability comes from an all-copper motor that runs with lower electrical losses, delivering consistent torque and quieter operation than many alternatives. Built-in thermal overload protection pauses the motor if it overheats and restarts it automatically when safe, helping prevent damage from continuous heavy use.

• Motor: copper-wound for longevity and efficient operation.
• Safety: thermal overload protection with automatic reset.
• Noise: designed for reduced operational noise during use.
• Maintenance: manual crushing function and flush rinse for cleaning.

How do I keep the macerator clean and prevent odors or build-up?

Routine rinsing with fresh water through the pump after each use helps purge residue and reduce smells. The manual crushing/macerating action aids in breaking down solids; periodic inspection and a quick fresh-water flush will keep performance steady and minimize buildup.

• Fresh-water rinse capability to clear the pump after emptying tanks.
• Manual crushing function to help break down stubborn debris.
• Simple disassembly points for basic inspection and cleaning.
• Reduced clogging rate—manufacturer estimates up to 95% fewer clogs due to blade design.

Who is this for: The Kitvance 12V RV Macerator Pump Kit is aimed at RV owners, campervan converters, and boondockers who want a portable, fast, and low-maintenance way to empty holding tanks without relying on park facilities. It also fits situations where short uphill discharge or compact, battery-powered disposal is needed, offering a practical mix of performance and convenience for weekend travelers and long-term mobile living alike.
