empty fresh water tank?

New first time motorhome owner. Home for a few weeks before we head out again. Realized that we had two week old water in our fresh tank and thought it best to empty it, so I opened the low point valve.. Now worried that I should have some water in so gaskets and seals don't dry out? What's the recommendation?

Drain, refill with water and bleach solution drive around a bit to hit all sides and top of tank, the rinse and fill again. I use the camco filter from Walmart.

Most all pumps are approved for "waterless" operation...

Not a water expert, but by reading these forums long enough the questions are asked time and again. Some of them has said that water will remain fresh in the tanks for as long as a year. Not my answer but what you may see if you keep reading. I do believe that 2 week old water is not old as long as it is in a clean tank. water setting in a tank or ne that is empty will not effect seals as there is only a tank with fittings for the lines that directs the water.

I certainly wouldn't worry about two week old water, assuming the source it was filled from was "city water" or chlorinated well water. Water that was safe to drink in the first place will still be fine after two weeks. Or two months.

No seals to worry about and you probably can't completely empty the fresh tank anyway. Most of them have at least a gallon or two of water in the bottom when they are "empty".

Put in about 1/2 cup of chlorine and fill it up.Let sit for a few hours, Drain and refill. 2 weeks it should be fine but if it smells then go the chlorine route and run all your faucets so both hot and cold come out.

I'm really tired of people saying the fresh water doesn't go bad. Place some water in a coffee can and set it on your back porch and see what it looks like in a few weeks. Your fresh water tank has air in it, gets very hot during the summer and creates mold. Mold can make you very sick. Better to be safe then sorry like my wife and I spending 2 days in a hospital because we didn't sanitize the fresh water tank on our first MH.

The water in my 5er sat for 6 months over the summer every year for 11 years and never made me sick. I never used any bleach, but did make sure it was full when I summerized each year.
