How about pulling your Pod into an ionizing radiation chamber.  That should take care of not only any bugs in the water system, but any bugs in the whole trailer.  Wink  If it's good enough for a truck load of potatoes it's good enough for a Pod???

Camco Drinking Water Freshener -- Keeps Stored Water Fresh Tasting & Odor Free
Contains: Sodium Hypochlorite solution CAS # 7681-52-9
Directions:
1.Fill tank to 1/4 total volume.
2. Pour 1 oz. Drinking Water Freshener into tank for each 20 gallons of tank capacity.
3. Complete filling of your tank.

What is not specified is the Sodium Hypochlorite concentration. However, for a 30 gallon tank, 1.5 oz. of this is used. The bottle is 16 ounces so that means there is a little over 10 tank fillings that can be done with this bottle. The French instructions give the metric measurements as 30 mL for each 75.7 L water.

I would not trust isopropyl (rubbing) alcohol. It isn't as toxic as methyl alcohol, but it is still toxic. I would not trust it in my water system, even if I were flushing it out.

OK, here's a CDC document with probably everything you ever wanted to know, and then some, about disinfecting using various treatments. Alcohol is apparently not recommended at the kind of concentrations we're talking about.

On a dollar-per-ounce basis, you might just pour in some rubbing alcohol. I used to get 98% pure rubbing alcohol at the local Walgreens. Don't know what it cost, but a couple bottles of that would do a bang-up job of sanitizing. And it's organic.

Not sure what you mean by similar?

Bleach is sodium hypochlorite, the Camco stuff's active ingredient is alcohol. Totally different chemically. Beach is considered hazmat, Camco's product is not. The bleach is more dangerous if you get it in your eyes and is highly toxic to aquatic life. Its a very well proven sanitizing agent though (maybe because its toxic to aquatic life?). 

But lots of stuff will have very similar reading health precautions on the MSDS:  avoid eye and skin contact, don't drink it, don't pour it in lakes or streams.Mostly common sense type stuff. 

For myself, I live next to a wetland area so I don't like to dump out any chemicals. Amphibians in particular are super sensitive, and I like to hear my frogs at night. So, for myself I just rinse my tank with plain water and don't drink out of it.

here's the MSDS for Spring Fresh


its only about 4% ethyl alcohol so 80 proof vodka contains 10X the alcohol. You'd only need less than a pint of vodka to be the equivalent, so you could drink the other 7 pints after which you wouldn't be worried about what the water in your tank tastes like LOL

Why not use Everclear?  You can buy pure ethanol for about $65 a gallon.  At a 4% dilution, you could do a lot of sanitizing, but I'd sure want to check with a water purification person to see if a 4% will do anything other than making it a nice party for the germs.

According to the Q&A on Amazon the manufacturer says:

Ethyl alcohol, Sorbitan Monostearate Ethoxylate 

I like the ethyl alcohol part but why not just use vodka? LOL

The other ingredient doesn't sound quite so great, its apparently some kind of emulsifier, maybe to clean out any grease or sludge that's in there:

Sorbitan monostearate can harm the integumentary system as it can cause irritation in the skin. In addition, sorbitan monostearate is bad for the digestive system. High levels of the substance can cause liver enlargement.

No bleach though!
