How long do you store fresh water in tank?

I drain every thing and refill each time, clean in the spring.

I drain my tank after every trip, including the hot water tank and the low point drains. I tend to drink the water that comes out of the tap on my RV. Of course, we fill up from home/city water prior to going anywhere, so we know the water is reliable. I haven't had full hookups lately as I've only camped at Ohio state parks. Looking forward to having FHU in the near future, however.
