    I am not talking about using a water fed pole or anthing.

    I recently started thinking about the water I'm using not being pure water. Now I know I'm only using applictor and squeegee with a bottle of water, but would it be worth me using pretty clean rain from my water butt and sending it through a coffee filter, instead of using regular tap water? It wouldn't really be any trouble...

    Rainwater is basicaly very soft water so just havesting it into a holding tank and running it through a basic filter to get rid of the crud comming down with it from the guttering is good enough for trad cleaning. I use to use a nylon sock to filter the crud out before it went into the holding tank/water butts.

    You can get a HM Digital TDS-3 Handheld Meter With Carrying Case
    http://www.daqua.co.uk/testmeters.htm from the likes of daqua for 12.60 to have a play at finding out how pure the harvested rainwater water really is.

    OK thanks guys

    Do you think there can be water soluble minerals running with the water off the roof? Should I give the roof, gutter and inside of the water butt a clean as well? Only a small garage roof and 15 foot length of gutter

    If you have a tds metre next time it rains put a cup out and test the rain water that collects in it. You will find once rinsed out with rain and you take another reading when collected again the rain water has a very low ppm reading of about 2ppm. However once it gets contaminated by roof tiles etc and flows into the guttering and mixes with tile grit, moss & muck it don't stay that low for long.

    Mine came out of the downpipe and after the sock filter on average of 20-30 ppm which is equivalent to very soft tap water without any harsh chemicals like chlorine being in it. However harvested rainwater picks up bacteria and micro bugs along the way too so don't go drinking it now will you. Also if left in say a water butt without a lid on it for a period of time the water will eventualy turn into a stagnant primeval soup with all sorts of wiggly thing in it too:D

    Indeed the water butt has a lid on. The water is pretty clean, just coming out of the tap without even being filtered.

    No, I certainly wouldn't drink it without boiling or sending through a propur filter or whatever.

    So smurf, what ppm is just the tap water in your area? Any idea what kind of ppm would medium hard tap water in the manchester area be?
