My Legacy 32 double ender is having head troubles. The Raritan Compact model pumps water into the toilet bowl but not out. The hose out does not appear to be blocked. The problem appears to be a rubber gasket/valve at the base of the pump mechanism. Raritan lists the model as discontinued. Does anyone know if parts are available somewhere? If not, are there recommendations for a small footprint commode? Thanks, Dan Green Popeye Oregon City, Oregon
