Correct if you have been using HW, it should be in the Normal, not Bypass position.

Wierdstuff,

Lots of good recommendations here, but a few details may be needed.

It takes about a tablespoon of common household bleach to disenfect 200 gallons of water! Don't go crazy with a cup or two of bleach in a 50 gallon tank.

In a previous life I was associated with a beverage company and clean tasteless water was mandatory. What you are looking for is about 200 parts per million chlorine to a volume of water for about 20 to 30 minutes. In this way you don't trash out any of the water system.

Chlorine is a reactant and it CAN damage features of a water system.

So, a tablespoon of chlorine in 50 gallons is going to be about 1000 PPM. Household bleach will be somewhat less than pool chlorine or USP chorine. No problem.

Let the solution (chlorine & water) stay in the fresh water tank for about 30 minutes then flush through every valve in the vehicle. Sink, Showers, hot and cold valves and commode. Try not to splash it on you, what your wearing or your AS.

Then flush out every tank with fresh water and you are done. Remember also that you do not need to heat the hot water heater water in any way.

Also prepare to change the water filter associated with the kitchen sink if there is one. The activated charcoal filter will trap the chlorine and reduce the filters effectiveness.

It does not hurt to pour just a cap full of chlorine (household bleach) into the fresh water tank ever so often to keep the little bugs in check.

Chlorine breaks down when exposed to air and sun light so it will go away after a very short while.

All the best and Happy Trails.

PS, where you smelling foulness when you were running hot water or when you ran any water? If only hot water you took on a load of "h2s" laden water (hydrogen sulfide) and the sacrificial anode in the hot water heater was liberating rotten egg smell. It's harmless in small concentrations.

Two things to be sure of when filling the fresh water tank: 1) Always use a potable water hose like the one that came w/ your AI, white w/ blue stripe and 2) Always check when filling away from home that you are using a potable source.

I didn't do #2 once and got a horrible smell in a day or two.

.

Do you add a capful to the water you're drinking? That is, even when not flushing the tank? If so, does it affect the taste much?

Jekkerville...thanks for that info. Everyone else seems to think we need so much more chlorine though. Are you sure using so little will disinfect everything?!

We always use our fresh water hose to fill the tank. And yes, we're careful to always use potable water. Last time we filled tank was from the outside hose bib at our friend's house back in February.

And since we've only been day tripping since that trip in February, we don't use much water. We don't drink it, but our dogs do. And a couple weeks ago, I went to fill the doggie water bowl, and noticed the smell.

So, yes, this would be cold water. We haven't used the water heater in a long time.

And, not that you asked, but, our bathroom/toilet does not smell, so I figured this was just related to the fresh water tank, and not the black tank.

The EPA and other organizations publish material on how to disinfect a drinking water source. Here's a link to an example:

WHO and most state public health departments also have procedures to follow to disinfect potable water storage tanks.

Emergency Disinfection of Drinking Water | Emergency Preparedness | US EPA
Emergency disinfection of drinking water is for adding chlorine to the water you're going to drink. It is designed to leave a chlorine residual of more than 1 part per million and less than 4 parts per million, in other words a safe level of chlorine for human consumption. That's not the same as disinfecting a freshwater tank. The document you linked to is near and dear to many Gulf Coast residents' hearts, because when a city floods during a tropical storm event, the city's water supply is compromised until the water mains have been thoroughly flushed. When we're under a "boil order" it's not always practical to boil the water if you don't have a heat source and/or don't want to drink hot water, so adding bleach to the drinking water is a viable alternative.

But the linked document does contain one important fact— use only unscented Clorox brand bleach, because it has consistent levels of chlorine in every batch produced, unlike some off-brands that may have varying chlorine content, so when you ad ounces or drops or whatever measure of bleach, you know you're putting in the right amount of chlorine to make the water safe.

If you're looking to shock-treat your RV's freshwater system and then flush it with fresh water to remove the chlorine, that's an entirely different matter and does require more chlorine. Your Airstream owner's manual— if you have one or can download one from the Airstream web page— should tell you how much chlorine bleach to add to your freshwater system to shock-treat it. My Airstream Interstate owner's manual says to multiply tank capacity by 0.13 to find the number of ounces of bleach to add. Since most Airstream Interstates have a 26-gallon fresh tank and a 6-gallon water heater, for a total capacity of 32 gallons, that is 32×0.13= 4.16 ounces of unscented Clorox bleach. Since fractions of an ounce are sometimes hard to measure, if you round up to 5 ounces you should do fine, because you're going to flush the system with fresh water afterward and aren't worried about leaving residual chlorine in the drinking water.

On Edit— The Airstream Interstate owner's manual also says to let the chlorinated water sit in your freshwater system for at least 4 hours. It also says that if you want to do it in one hour, double the amount of bleach.

So many threads and posts on this topic.

If you're not talking about shocking or emergency disinfectant, Protag summarizes the manuals and the AI books, etc. 1/2 cup of bleach, 4 hours. Then what everyone else says about flushing and repeating with a clean, potable, rinse.

If you can arrange to be driving for those 4 hours, to slosh the water around, so much the better. So we do ours as we're leaving one location and heading toward another, both with hookups. Makes the filling, flushing, and rinsing convenient.

We've never used our water tank. So out of curiosity I looked in the owners manual. The owners manual states:

To clean the tank, pour some bicarbonate of soda into the filler spout with several gallons of water and allow it to stand for a minimum of four hours. Then flush the tank out by opening the drain valve and running fresh water through it.

If the water tank must be cleaned further, the following procedure is recommended.
1. Prepare a sodium hypochlorite solution using potable water and household bleach (5-1/4 or 6%) in the ratio of 1/4 cup of bleach to 1 gallon of water.
2. Pour 1 gallon of hypochlorite solution for each 15 gallons of capacity into the empty water tank.
3. Add enough potable water to completely fill the water system.
4. Allow closed system to stand for three hours.
5. Drain the hypochlorite solution from the system and refill with potable water.
6. Excessive hypochlorite taste or odor remaining in the system is removed by rinsing the system with a vinegar solution mixed in the ratio of 1 quart vinegar to 5 gallons water.
7. Drain the system and flush with potable water.
8. Drain the system and flush with potable water.

Simple! Thanks for the review!

Back in my home brewing days we used iodine as a disinfectant. The military and the Boy Scouts also used iodine to disinfect iffy water supplies. Might be worth considering for folks that are nervous about using chlorine.

Elemental Iodine is poisonous. It is one of my childhood memories after getting a cut... little glass vial with a glass applicator wand, burned like L, stained my skin and the cool but spooky little skull and crossbones on the label.
If you prefer Iodine, you would need to use Potassium Iodide. It's what we used in the field in our canteens. It would be doable but expensive.
Chlorine is safe(er) at trace levels, but yes can be just as bad as anything else at higher doses.
