The RV Sani-Con Model 5800-6004 waste management system is more compact than the standard model 5800 and designed for those small waste compartments.  Installation is easy. Just twist it onto the end of the 3" RV sewer connection, hook up the wiring and you are ready to empty the tanks. Can be used as a portable since it just twists on. The gray water bypass system allows the gray water tank to empty around the pump at parks with sewers.  The system includes the new 21' x 1" retractable hose which retracts to only 7 ft. The molded nozzle includes a threaded sewer adapter for both 4" and 3" threads. Lifts 20' above the pump, up to 350' away at a 12-14 gallons per minute flow rate, the highest in the industry. The overall length of the pump and motor when installed is only 8.5" , which takes up very little room to install.  Requires a 12 volt circuit with at least 20 amps available. Do not hook to a light circuit in the sewer bay or to any other appliance that might be used at the same time, such as the water pump. All wiring terminals, breaker, mounting screws and 20' of wiring is furnished for installation.
