Do you sanitize your S&B water system???
Your house water is NOT a holding tank.
Have not bleached mine yet. But then my city water will kill anything.If I use well water or other unknown source while camping I drain and fill with my city water at end of the trip.
Adding city water to a tank to sanitize it does absolutely nothing.
City water may 'smell' like chlorine but it does NOT have bleach in it it to kill anything. It is added at the filtration plant to kill bacteria BEFORE it is released to the city's water. All you get is the "smell"/"odor" of chlorine trapped in the lines. Leave a glass of tap water on the counter and all the odor and the taste from the odor of chlorine disappear within minutes.
RV fresh water tank is an unsealed holding tank which is subjected to the ambient temperature of the outside air. Which most fill with a garden hose, many times picked up off the ground or from inside a bay etc, that also can carry a multitude of bacteria on it adding it to the water in the holding tank.
My tank is mounted on the inside back of my MH with an access door allowing full view of the holding tank. I can SEE all what settles and/or can grow on the bottom of the tank and side walls.
Are you gong to die? Probably not. But my guess is many a bout of diarrhea or upset stomachs while on the road RV'ing is NOT from having too much BBQ and Beer from the night before camp cook out. :W
