Jabsco 18555000A Portable RV Macerator Waste Pump Kit 12V DC

The Jabsco / Flojet 18555000A is a portable, self-priming 12V DC macerator waste pump kit engineered to simplify holding tank evacuation for recreational vehicles. Connecting directly to the standard RV waste outlet, it replaces bulky 3-inch sewer hoses with a clean, easy-to-handle 3/4-inch garden hose connection — letting you pump waste uphill, around corners, and over longer distances than a conventional gravity dump allows.

The integrated stainless steel macerator grinds all waste and tissue typically found in RV sanitation systems down to a maximum particle size of 1/8 inch, enabling smooth, clog-resistant flow. The self-priming pump section allows the unit to be positioned above the holding tank for convenient placement. At up to 9 gallons per minute, the pump empties a typical 30-gallon holding tank in under three minutes.

Key Features:

• 12V DC operation — runs on your RV's existing electrical system
• Up to 9 GPM (43 L/min) output at 3m total head; 16.5A maximum current draw
• Stainless steel macerator grinds waste to 1/8" max particle size
• Self-priming design — can be mounted above the holding tank
• 3/4" garden hose discharge port eliminates 3" sewer hose
• Connects directly to standard RV waste outlet

Important: This pump is designed to handle waste and tissue normally found in RV waste systems only. It will not handle hard solid objects, sanitary napkins, or rags.
