I don't have any hard and fast rule, but if it's been more than a couple of months I just pull the drain valve and refill. Also I don't fill the tank until shortly before the trip, so whatever is in there is going to get a shot of chlorine with the new water.

Less than a couple of months, I just top it off an go.

As far as leaching chems, the plastic in water bottles versus the plastic tank, hoses, fittings? What makes us think one is any better than the other? We keep flats of bottles for years at a time without any concern or noticeable taste change. The difference with a fresh water RV tank is a bit of air flow in/out, and the longer that sits, the more likely that taste may be altered.

BTW, as far as the chlorine in the water, it is dissipated within hours or days. It has already done its job and from that point isn't going to be a factor.

While the water in the tank might be good for a while water in the water heater gets a odor if it sits for a couple of weeks.

Weather or not you believe it is the water or the bottle, emergency management stations that maintain bottled water for emergency situations must discard and replenish upon expiration dates.
That being said I keep water in my tank year round and only refresh if more than 4 months.


If you cannot take good care of what you have, you will not have anything good for very long!!!

You may want to add Drinking Water Freshener that prevents algae and slime from forming in the tank. Walmart and Amazon sell it for under $5 a bottle.

Cleanliness is next to Godliness. A clean(sanitized) tank with clorinated water will last a long, long time. I once traveled in a vessel and we had never changed the water in the tank since it was filled. As stated, the water doesn't go bad, things may grow in the tank and the gasses in the water will gas off giving it a old, musty taste but it can be very safe for years.

Our emergency water storage at home is in 55 gallon blue food grade drums with a couple of tablespoons of chlorine added and we usually wait three or four years to change. When we do change the water, we use it for irrigation around the house.

for us, we keep our potable water tank full. if not used, we drain every month and refill and not to mention, don't forget to run the water, hot and cold to replenish what is in the lines. For me, a full tank with chlorinated water is better than an empty tank. it lessens the potential for bacteria growth. Flush and fill regularly and and you will be fine. If you have a concern, add a little chlorine/ bleach, maybe a 1/4 of a cup to 50 gallons, run fixtures, let sit for 24 to 48 hours, flush it all out and refill, you should be good to go. as far as filling when you get there, where are you getting the water and what quality does it have. Your city water should meet drinking water standards. we travel with full tanks all the time, drink it and use it for cooling and everything just like we are in our block home in the concrete jungle. Good Luck & Be Safe ! ! !

There is no generic answer as every water tank is different in age/condition.....water being used.....hot summer heat vs cooler weather/etc.
