That is what the forum is all about... We learn from one another and hopfully the experience will save another from problems or at least know what to do when there is a problem.. My simple solution is to ask the vendor of the tanks what they recommend for support then do that when I have it replaced. We never travel with more tha a couple of gallons of fluid in the tanks. Even with the fresh water tank maybe 10 gallons.Of course we pay close attention to flushing with the valve closed.....except this one time....
