Hopefully, you’re reading this post before embarking on your epic 2-week RVing adventure – not because your wife is throwing up in the RV bathroom and you’re panicking that it’s your fault for not sanitizing the water system. (Which, sadly, it is.)

As an RVer, you’re in charge of your own utility hookups. Anytime you aren’t connected to a city/campground water source, you’re in charge of your own freshwater!

And since we all know freshwater doesn’t stay fresh … just how long does the bacterial clock tick? How long can you let water sit in an RV tank before it goes bad?
