The Kohree unit combines a high-efficiency motor, a 4-blade SK5 steel grinding head, and a complete accessory kit so you can pump out tanks on the road, at home, or before storage. It’s designed to reduce clogs, preserve battery life, and handle both thick and thin waste reliably.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly will it empty my RV tank?\u003c\/h3\u003e\n\u003cp\u003eThis pump is rated at 12 gallons per minute (GPM) under ideal conditions, meaning a typical 40-gallon (150 L) tank can be emptied in roughly four minutes theoretically and usually under six minutes in real-world use. Performance depends on hose length, vertical lift, and how full the tank is.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFlow rate: 12 GPM nominal\u003c\/li\u003e\n  \u003cli\u003eTypical empty time: ~4–6 minutes for a 40-gallon tank\u003c\/li\u003e\n  \u003cli\u003ePressure capability: up to 15 PSI with 10 ft vertical lift\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it clog with toilet paper or solids?\u003c\/h3\u003e\n\u003cp\u003eKohree’s macerator uses a 4-spiral SK5 steel blade assembly that grinds solids and toilet paper down to about 1.6 mm particles, dramatically reducing the chance of blockages.
