    finding it hard to get deionised water!

    All,
    I have just got back into developing films. Now I have my chemicals sorted , but when it comes to deionised (which working at a school I thought would be the least of my problems!), I am hitting a brick wall. The school I am at does not have any!!! They do not use any in the chem lessons (H&S has stopped a lot of experiments!!).
    So I thought ok I will buy some bottles of it. NOOOO! at £2.40 per litre bottle!!!
    So I am stuck for a cheap source of deionised water. Our tap water whilst not very hard does tend to leave calcium deposits on things.
    So ideas please?
    I don't really want to have to spend a lot for a filter system etc (no where to put it perm).
    I live in Cheshire UK so obviously there is no point in saying 'I get mine from walmart for 20cents a gal' lol

    Use distilled if you must, but often tap water is just fine as long as no precipitate forms.

    Distilled water is often available in stores. Deionized water is also sometimes sold as water for steam irons. You can also buy low volume water purifiers that produce deionized water. In many countries the Brita brand is popular and widely available. In any case, look for purifiers that have the purple deionizing resin filters rather than the simple black (carbon) or white filters.

    As a matter of curiosity, why would one use deionised water for mixing film developers?

    Use a Brittax or similar water filter, that's enough for developers and cheap as well. We iuse them for drinking water atr home as well.

    Deionised or distilled water is better for mixing developers from scratch particularly in hard water areas.

    I would have a look round the car assessory shops and small independent garages. I,found a local garage the cheapest at about £2.50 for five litres. The big flashy petrol stations and super stores all seemed much more expensive.

    I don't think the OP said what he was using this for, but if it is to be used in the mix I would ask the same question. However, dunking the film into deionised water for about 30 seconds after the wash will give you a film free of drying marks. I always do it. You can get this from any branch of Tesco/Morrison/Halfords.

    Wow. In the US, lots of grocery stores have a refill station where you can bring your own jugs and fill them up with filtered drinking water. The ones at Whole Foods also have a de-ionized spout and it sells for the same price as the filtered water, $.40/gal.

    I mix all my chemicals with de-ionized because I can get it so easily and cheaply, and I figure the consistency eliminates one more variable from a process that I can all too easily screw up.
