From my recollection, to be utilized as a soil drench the solution should be diluted anywhere from 1:10 to 1:20. Foliar spraying has all sorts of further dilution recommendations but what I have read is that dilution of SOME SORT is recommended.
In the grand scheme of things, I don't think the tap water will be the end of the world when used for dilution water. I would encourage you to think about ways to either store/vent a larger amount of dilution tap water when you next brew a JADAM solution or look into a way to capture rainwater if possible.
I'm currently working on a compost tea system that involves a whole bunch of 5 gallon buckets. I'm hoping to work on rainwater capture into a large IBC tote to pull from but thats in the future. For now, I'm filling buckets from the tap and letting them sit for a day or so.
