Storage of Fresh Water - How Long

[rookie_rv]

Hello, Rookie RVer :C here! Can you provide any “good to know” tips, about storing fresh water in tank? I just installed a double water filter on “MidLife” (Winnebago Vista 30B) and its made a world of difference. How long would you suggest keeping water in the tank? I’m thinking after a certain amount of time its not a good thing. Prior to installing filter I use to empty tank and water heater after every trip. I couldn’t find any post on this.

Thanks in advance!

As for the fresh water tank, my rule of thumb is if its going to sit for more than a couple weeeks I will drain it. I carry less than 1/3 so not much is sent to the ground.

As for the water heater, I drain mine at the end of the season. Clean it out using a water heater nozzle on the hose. I have never understood the folks who drain after every trip. My question is do they drain their water heater at home when they leave?

I have chlorinated city water. As long as I was going back out (or using it at home) within a month, I didn't drain it. If the RV was going to sit unused for more than a month, than I drained it.

Same here , all tanks empty and cleaned after every trip. We do carry bottle water to cook and drink. Got sick once on a trip from the water and that is not a good thing when traveling. Can't help you your on your filter.

A week without significant use of water in the tank and refilling from a fresh water source. Temperature plays an important part of this. I’m not a water waster but why push it. I empty after every trip. I sanitize before every trip.
