We have a 2014 Beneteau 38 that we keep in salt water with a single Jabsco Quiet-Flush head located amidships. My better ½ and the kids - who in the late hours of the night are comfortably snoozing in their cabins - are woken up during the night when I get up to ‘make water’ and flush the toilet. Not surprisingly ‘Quiet-Flush’ is an oxymoron. ‘She who must be obeyed’ has dictated that going forward the toilet will not be flushed between 11pm and 8am. I’ve told her that given the raw salt water in the system, the hoses will get coated with calcium if the bowl and system is not thoroughly flushed after each use…to which she suggested that I flush the system out with fresh tap water before retiring such that no salt will be present in the bowl during the hours of 11pm and 8am…after which time I can flush my 'water' out. Is my wife’s wise? Said differently, will fresh water in the hoses/and keeping the urine in the bowl be OK? Please advise and thanks in advance.
