    Need to clean my water tanks. Got a stomach bug and wonder if it could be the water tank as we do drink from it.
    Anyone got any suggestions what to use and how to do it? I know there are some things in the accessory shops but I wonder if anyone has a preference?

    well , the stuff they use to disinfect baby's bottles is actually very dilute sodium hypochlorite which you can buy more concentrated as a common or garden domestic bleach ; so a couple of teaspoons of that added to a full 100 litre water tank , left overnight , will kill all the germs you might have

    unfortunately , as you will have noticed in a swimming pool or your domestic water supply if it has been infected , it leaves a nasty smell and taste .....so plenty of rinsing through will be required to get rid of that !
    but if your domestic water supply currently smells of chlorine just filling the tank with that for the night will do the job , difficult to get rid of the tang then , what do you rinse it with :Doh:

    if you fill it with uk tap water a few times it will come clean .thevery small amount of clorine use will do the job. .

    Try this link. below. We have just used these tablets for both the clean water and waste tanks.

    OH was complaing about the lousy taste in her tea and we were getting "bad egg" smells from the waste.

    Happy to say both problems have now gone completely.

    IIRC, 10 tablets cost £5 incl P+P and they arrived the next day. We have no connection with this company but can recommend the product. It solved our problem.

    The post above refering to Zappys blog is the best and simplest stuff I've used. (review here: http://www.doyourdream.co.uk/2010/05/cleaning-fresh-water-tank/ )

    I believe a post was made here to tell us all about it but it got moderated for advertising :Rofl1: despite it being really very useful. It is quite a long running and positive thread on the more moderated "factual" site so a bit strange really.

    After cleaning my tank a week or 2 ago I have removed it to fix a drip (where I fitted the ice defrost element :Doh: ) and so looked inside the tank even close up it is clean and smells fresh (bar some sand at the bottom) and considering (a) how much we've used it and (b) that it has been left for most of the winter, then its quite a good result:thumb:

    ETA: I have no connection with Zappy or his product - just really pleased I saw him saying about it, and it does what it says on the tin. (Well - A4 paper!)

    We always fill our tank and add Baby Milton and leave it for 24 hours , we also do our waste tank with it aswell to stop the smells ,
    We do have a 2nt tap fitted in ours for Purifying water and find it is brilliant for using all over the country , no need to buy bottled water outside the UK .
    very easy to fit and would recommend :thumb:

    one of the best items i'v bought for the van.

    general ecology water filter.

    Specifications

    you can put dirty ditch water in your tank and it comes out of the tap germ free and purer than tap water.

    filtration is so fine it even removes virus's.

    not a cheap option but well worth the money (it can be bought much cheaper than the RRP listed)

    will filter nearly 2000ltrs before the cartridge needs changing and the system can easily be swapped from van to van.

    Nothing Strange at all, you can dress an advert up in some useful information, but its still an advert. it was an advert and they have to be paid for. Its how we survive, Its a fact we don't have a 50k a year in subs (as well as advertisers) so we rely on advertisers paying to promote their products. Every day, spammers try to take advantage, that useful post was spam, and how I hate spammers who leech of others to get something for nothing. :Angry: The same link has been posted by others, and this is not a problem, but when the seller tries to promote it directly, that is Spam.

    Most Spam is caught before anyone sees it, if I left it alone for just a week this site would be a very different place, so no, not strange at all, just good practise:thumb:

    Hi Lenny I think you are missing the point when using Milton or any other Bleach, the whole idea is only to leave it in the tanks etc. for an hour max, or so then flush it out-- flush it out no damage can be done in that time :thumb: it is only if it is left in the tank :Wink: Also our tap water is treated and should be fine but I have left a clear plastic bottle full of tap water in my garage for a few weeks / months and gone for it only to discover that it is full of green algae,:Eeek: a small spot of bleach shifts this in about ten mins / rinse out then refill and drink :Rofl1:

    Tablets

    I have always used sterilising fluid which normally contains 5% Sodium Hypochlorite and leave for 30 minutes with a ten minute drive then flush out twice. It does however state on the bottle not to use on anything metal. For the short time I leave it in once a year, I'll take the chance.

    The tablets in the blog are also Sodium Hypochlorite if I'm not mistaken so I don't actaully see any gain from using them and they probably wouldn't be recommended if the solution came into contact with a Truma boiler or similar any more than the sterilising fluid would be recommended.

    A bottle of household bleach we have states 5% Sodium Hypochlorite, 5% Sodium Hydroxide plus surfactants so this is probably not a good idea.

    I'm sure I read some time ago about using steradent or something similar but I haven't tried that. Haven't lost enough gnashers for that yet. :RollEyes:

    Winnebago instructions say to use bleach. We did this and it did smell very clean and chlorinated for a few tankfulls after despite flushing several times!!
    We dont drink it though so not as much of an issue for us. We used to put bleach down the sink in the caravan if smells came up in the summer. Will proabably just do the same in the MH, pour a bit down the drain into the grey tank

    Elsin, made by Elsan, the best water and tank cleaner going.

    Sodium Hypochlorite makes th water taste and takes several flushes to remove just the smell, even after 4 flushes I could taste it in my tea.

    The Elsin stuff doesn't taste, cleans tanks and sterilises water. Perfik!

    I think you are are missing the point. If you read the blogs article it is about getting the strength right which you can't do with bleach it also contains other things. I was very pleased with the results and no taste at all.

    I really don't understand why so many of you put chemicals in you drinking water tanks, there is more that enough bug killing chemicals in the UK water supply to do the job without adding to it.

    Also plastic absorbs chemicals and some chemicals even combine with some plastic's to make a secondary chemical!

    As your tanks and pipes are made of plastic you are just adding to the off tastes that you will not like.

    Of course if you get you water from a unknown source like a river, lake, or your in a country were the water is suspect then by all means put water purifying chemicals in to the tank.

    Filtration as suggested earlier is by far the best way to get a drinkable water from your tank, expensive yes, but you will never regret it, that is if you don't cut corners and buy a ineffective one.

    Doug...

    i think alot of you have midded the point. if you fill with chlorinated tap water just about every time .the water cant wont go off. dont compare with clear plastic bottles in the light somewhere. .if you do putdirty water in just flush out with more chlorinated tap water .you dont need to add anything. water should last from one year to the next.
    yes the filter pappa uses is good and even removes chlorine. i use a doulton berkenfield with silver inlay but only if i have knowingly put not nice water in .sometimes we use riverwater if inthe wilds .but on return run good tap water through and away you go.
    have a word with your local water plant operatives get their advise .
    if you are lucky get a visit to the works its very informative and could ease minds of some of you.
    cheers alan.
