Yeah, thank John Howard for that one....actually I don't know why people aren't screaming from the rooftops about it.

I think there is some sort of sediment filter in the tank, but I don't think it's too fancy. I remember my grandads big old corrugated tank that filled from his roof and no one got sick from sediment or anything.

Call a tank place up I suppose, although Trill might come in and have more info.
