About 2 quarts of chlorox jostled around with a ten minute trip for fuel on these E TN roads, dumping the tank and then a refill with a cup added that I will circulate through the fixtures.

I am a little careful about running too much chlorine based chemicals throught the plastic piping. About 10 years ago the type of piping used in our coaches was at the heart of a national class action lawsuit because it was failing due to high concentrations of chlorine in water supplies. I don't think my year of coach had piping made with the problem material, but I will not take a chance.

Whatever contamination my tank received it was slight.
