How long do you keep fresh water in tank?

Now that I know most people travel with a full fresh water tank in case of need, I want to know how long do you keep tank before dumping and refilling?

I had always heard dump after 3-5 days.

We never dump fresh water, it gets used and re-filled regularly.

I top off at every campground before departure.....keeps it fresh.

City/town water typically has some level of chlorine in it so dumping that quickly is likely not necessary. I will dump if the coach will be sitting unused for a while before the next trip.

I drain the fresh water tank and sanitize it and the pipes once a year. We use the water from the tank whenever needed. We top it off when needed. And yes we drink the water from the tank.

I'm not sure most people do travel with a full FW tank. I travel with only 1/3 to1/2 tank. Only time I fill it up is if I know we will be boondocking.
That said I'll dump and refill about every 6 weeks or so. Sometime longer.

We go through a tank of fresh water in a week [under normal circumstances]. Not much need to dump "stale" water. If we were to winterize, we would dump at end-of-season, of course. \ken

We have city water, from wells but treated. I drain the tank over winter, then put water in before we take our first trip. After that I fill up as needed which isn't very often. Never do drain the tank otherwise.

I try not to let water "sit" in the fresh water tank for long periods of time ... if/when we find ourselves with a full fresh tank and are about to head home where I know the coach will be sitting for a while - we'll simply increase our usage (more/longer showers, be a little more "wasteful" when washing dishing, add some extra water to the black tank prior to dumping, decide it's a good time to wash some of the "patio" gear, etc.) so that we're not stuck heading out next time with a tank of somewhat "stale" fresh water. We're not OCD about it ... we'd just rather have "fresh" fresh water in the tank when we head out the next time.

We dump the water after each trip unless we are going on another trip within 2 weeks.

I generally flush every 2-4 weeks. I do not add water if I've had experience with the city water that tastes bad such as hard well water or with a lot of calcium/lime/minerals. As full timers I sometimes carry too much fresh water due to the above reasons. I'll taste it before adding. Yes we drink the tank water.

We are weekend warriors and we do the same...

I usually do a chlorine flush at the beginning and middle of every season.. just because chlorine is cheap and so is my time.. Plus, we do drink from the tank..
