Facing that rotten egg smell in your bathroom onboard? Raritan is now offering its Fresh Head, the first manual marine toilet that uses pressurized fresh water as well as removes calcium deposits in the discharge hose and helps cut down on any unpleasant odor. The diaphragm-type pump and telescopic handle make flushing extremely easy, and houseboaters can choose how much water is needed. A lever lets water into the bowl to pre-wet it for a better flush, and backflow is eliminated with a built-in vacuum break and lock-out feature. Fresh Head is a direct replacement for competitive models, no thru-hulls are necessary for installation, and it has a starting price of $499.
