    • Dometic MasterFlush 7120 Electric Macerating Toilet has the ORBIT 360° Rotating Base and Fresh Water Flush
    • Fitting a standard marine toilet in a small boat head usually meant sacrificing comfort and appearance for the sake of fit and function
    • However, the Omni-directional, ORBIT 360° Rotating Base Installation Technology puts a whole new spin to basic marine heads with the new MasterFlush 7100 Series of Orbit toilets
    • By providing a full 360 degrees of bowl-to-base rotation, the Orbit toilet base can be positioned in any configuration to maximize even the smallest installation space and accommodate diverse plumbing layouts
    • Full 360-degree ORBIT bowl-to-base rotation allows limitless base positioning in small spaces and diverse layouts
      • Several features enhance the installation possibilities of 7100 Series macerator toilets
      • Adjustable toilet base
        • Toilet base can be positioned so that macerator pump housing extends in any direction from the center of the toilet
    • Floor plan flexibility
      • Macerator pump allows toilet to be located up to 40 ft. (12.2 m) away or up to 4 ft. (1.2 m) below holding tank or other discharge line destination
    • Small footprint fits in most any head compartment
    • Employing the same large enameled seat and deep ceramic bowl size of a residential round-front toilet, the 7100 toilet Series introduces a new path to better comfort for owners of small boats
    • Smoothly contoured seat-to-bowl design conveys an expensive look without the extra cost
    • The deep, rounded slope adds not only to the appearance, but also to splash-resistance during use and while underway
    • As with all Dometic MasterFlush toilets, the 7100 Series assures trouble-free, odor-free performance by virtue of its unmatched maceration effectiveness
    • A rugged, glass-filled nylon twin impeller instantly draws effluent into the macerating chamber, where the 10-bladed stainless steel cutting wheel pulverizes waste and ejects it to the discharge line/holding tank
    • Includes powerful macerating flush
    • Uses as little as 1/3-gallon (1.2 liter) per flush
    • Residential-size toilet seat and deep bowl for hygienic use
    • Includes Model DFS-1F Flush Switch
      • "Normal" flush switch
      • Pressure activated
      • Toilet flushes as long as switch is pressed
