I just keep adding water to my tank, so it's always being used. It has probably sat at the most for 2 months without use at one point. We drink a lot of bottled water, but for the shower, well we don't drink that.

I am always adding water to the tank. I use city water that has chlorine in it so does provide a degree of safety. It's a sealed system withh no light so it will last a good while. I've gone 2 months and everything has been fine.

Just make sure to dump the hot water tank if you're not using it for extended periods, especially in the summer high humidity and heat. That is where you'll get the rotten egg smell started very easily.

Leave the hot water off and it will not smell. If you are worried add some unscented chlorox.

It is worth noting that Chlorox changed their formula to increase the amount of chlorine in an ounce of bleach. (New Concentrated package) Most of the old tables do not reflect that change. The new standard is 3 drops/ qt. There are tables on the internet to expand that out. I think it comes out to ~ 1 teaspoon for 10 gal. I add that for spring cleanout then add more water after cleaning just to help flush the system then reduce the concentration with more tap water. Given the chorine in the tap water that is a heavy dose. I also prefer to add the chlorine via the fill hose so it also gets a cleanout. ;-)

I leave mine for months at a time , always have and I drink it too ! I service/freshen the water system once every couple years. Even after sitting it tastes fine and I know my system is clean. Both of my Motorhomes I keep full at all times for Earthquake preparedness and when I leave in either one I never drain the tank , I just use that water.
