Is it routine to sanitize the fresh water tank? What products could I use? How's it done? My wife's a little leary of water that sits for a while.

I had to do this when I got my Westy.

Open up the water tank (inside the van) and unscrew the top part that's under a metal plate inside the cabnet (ablve the electrical outlet).

Fill up the tank with h20 and a small amout of bleach. I used 1/3 cup bleach to 13 gla.

Mix it up, let it sit for 20 min.

Drain it.

Add about 1/3 water back into the tank and scrub with baking soda.

Drain and then rinse.

Leave top open with a small fan blowing into it, and leave the drain off. This will allow all the moisture and bleach to leave.

Worked well and didn't leave any funny taste.

If your wife is really freaked, just give her a gallon jug of "spring" water. And use the water in the tank for washing and cooking... Drink the spring water and use it for coffee and so on..

Here's an article on treating potable water tanks in RV's:

http://www.doulton.ca/rv_dilem.html

We treat the tank in our Westy at the beginning of every season and give it a rinse afterwards. You can still smell the bleach in the tank for a short while, but there's no taste in our drinking water thanks to our Culligan RV water filter.

The Culligan filter (model US-316) is a nice small unit that fits in the cabinet under the sink, without having to remove the shelf. It has a charoal filter which removes all the bad tastes and odours from the water. We also have an inline filter that we attach to the when we fill our tank, so we start out with fairly clean water to begin with.

My Vanagon is not a camper, BUT, my motorhome watert tank?
When ever I fill it, I add a 1/2 cup of bleach.
It's a fifteen gal tank and I use it for washing only.
Drinking water, I use bottled...........
My MH is a 1977 model and the tank is super clean.

Thanks for the input all. I did the 1/3 cup bleach per full tank, let them sit a day. I then drained, refilled with freash water, let sit a day. Finally, I drained then left the tank open top and bottom to adry out. I used a little bit of the wife's stockings to cover the openings so no critters could get in.

I know this is a really old thread, but I noticed every one saying 1/3 - 1/2 cup of bleach for the tank. That sounds low. Back in my homebrewing days (need to start that up again) I used 1 oz bleach for every gallon of water to sanitize my plastic and glass equipment. For a 15 gal tank that's almost 2 cups(1.8 to be exact). Let stand 30 mins, drain, rinse with hot water and let air dry. Some brewers would skip the rinse, but I used a high pressure hot rinse.

The FAQ is your friend again. See section 76. As an example:

This thread talks about the subject topic.

There is more information available if you follow the links in the FAQ.

Keep it clean!

I haven't seen mention in any threads of using iodine sanitizer, but I have a restaurant-sized bottle left over from my homebrewing days, and we use that each year.

We make sure the tank is drained each winter to prevent freezing, then sanitize it before the first trip of the year.

Like some other folks we fill the tank only from the inside of the van, and add a few ounces of iodine directly to it, let it sit a few minutes, and run it through the pump (be careful pouring, undiluted iodine stains). The outside connectors were replaced some years back but we don't trust them and believe their leaking has led to some seam rust. (For the same reason we've stopped using the city-water connector entirely.)

I don't know how iodine compares to bleach in efficacy but when diluted iodine is tasteless and odorless, and probably less toxic.

I've put a little beach in once, now I just add a few gallons, drain, then fill up, and drain it when I get home.

I know that water can "go bad", but really, we're not brewing beer here- just carrying water. Bleach kills stuff because it's toxic- nastier than any small amount of algae or something. As long as you have good tap water, I wouldn't fret it.

Don't forget to run a fair amount of the bleach water through the pump, hose and faucet. I like to do mine before I put it away for the winter. Treat, drain and close it up. In the spring I give it a good rinse before use.

As well as disinfecting, I got rid of 29 years of water deposits in tank last summer when tank was out. I used a bit of diluted muriatic acid (HCl).

No scrubbing involved ( I did not want to add any more dirt/bacteria harbouring crevices.

Water deposits are unsightly but I'm not sure they are of any danger.

Bleach will react with plastics, and the resulting toxic compounds will adhere to the surface of the water tank and slowly elute into the solution. Is there any real health risk? No one really knows. The Europeans do not allow the use of bleach to disinfect water supplies, and instead oxygen is used. If you have kids you might want to think about that...

one of the first, if not the first, stages in infection is attachment. So getting rid of the deposits is not a complete was of time Smile

If you can get it, peroxyacetic acid (peracetic acid) is a great food safe sanitizer. Has a bleaching effect to.

Don't forget to replace your hoses too. I used anti-microbial Tygon silver:

How hard is it to replace hoses?
Is removal of cabinets needed?
Any pearls on this?
I assume HomeDespot or similar will have all the bits of hose and clamps needed? No need to mailorder from GoWesty or similar?
Any advice out there on what inline filter to mount between the tank and the faucet?

While removal of the cabinets is not strictly needed, it can be a bit of a pain. There are a few clips that attach the hose to the body; they are inaccessible without removing the cabinets. If you pull hard enough on the hose, the clips will pop out but without removing the cabinets you can't reinstall the clips.

I didn't want to remove my cabinets (again) so I just pulled the clips and didn't reinstall them. I used a barb fitting from the old hose to the new and I just fished the new hose through by pulling the old one out.

Here is my post on a water filter. Still working fantastic 3 years later; I have changed the filter once. The 0.5 micron filter does slow the flow of water a bit but I don't mind.

We're firmly in the "don't drink it" camp. If water must be drunk, then bottles are cheap enough and much more pleasant than tap that's been sat around for days with a taste of purifier.

Otherwise, let's be honest, there's far more interesting things to drink.

no offense, but i wouldn't trust ehow to tell me how to brush my teeth, much less sanitize a water tank.

lemon juice is not a 'deodorizer' nor a 'sanitizer'...i wouldn't put a food product in my water tank. and i wonder how many lemons it takes to make a cup of lemon juice?!

i've personally never seen anything of use on ehow. i always wonder how it gets such high placement in search results....
