This one is not just indigative to Vacuflush. Why does that boat smell so bad after all I have done?
answer; Permiated sanitation hose. Grab the sanitation hose tightly with your hand and hold on to it for 15 seconds. Now smell your hand. If that smell is there the only thing you can do is replace ALL the sanitation hose. I highly recommend the use of Sealnd “odorsafe” hose. It is a little more expensive but worth it. Sealand gives a 5 year warranty against odor permiation. Other white sanitation hose can permiate in as little as 1 year. This is not a job you want to do very often. As always, ALL these products are available on our webstore at www.marinediscounters.
