RV Macerator Pump, 12V 12 GPM, Quick-Release Waste Sewer

12V RV macerator pump drains your black tank faster and helps prevent hose clogs by shredding waste into pumpable slurry. Built for portable, long-distance dumping, it connects to a standard 3 in RV outlet and pushes through a 1 in hose barb. The quick-release connection and included clamp streamline setup at campgrounds, marinas, and remote sites while running directly from your vehicle battery.

• Delivers up to 12 GPM flow to empty large tanks quickly and reduce waiting at dump stations.


• Connects to a standard 3 in RV waste outlet; shreds solids with dual four-blade impeller for smoother sewer transfer.


• Includes a quick-release valve, metal hose clamp, and 7 ft power cord for faster hookup and control.


• Supports long-distance drainage with up to 10 ft lift for flexible routing in motorhomes, campers, and boats.


• Enables rinse-cleaning via garden hose joint to flush residue from the pump after dumping.

Designed for RV, marine, and motorhome waste management where gravity dumping isn’t ideal, this portable sewage transfer pump combines a copper motor with dry-run protection, overheat protection, interval work cycle, and low-noise operation. Use it for black water tanks, sewer connections, marine toilets, or winterizing/anti-freeze kit setups. Keep it in your storage bay so you’re ready when dump access is tight—grab yours today and simplify every dump routine.
