I am not quite ready to do Jadam in large scale yet (no land) and want to try it out small scale first. Is tap water okay? or would using tap water filtered through a Brita filter be better?
I have access to water for farming and could check. You say "add small amount of JWA in the water, and if it is soft water it should be clear but if it is hard water, then Color of the water shows blury." But JWA itself requires soft water. Is there a way I can test if my water is hard /soft another way?  

Can you give me US measurements for brass fittings? What sizea are 20A and 15A. I have never seen units like this. Thank you  

Where can I buy from the “shop”? I don’t see a way to purchase some of these parts
Thanks!  

Please how do I combine JS JWA and JHS to treat this Black Cocoa Pod that is destroying my farm? It is caused by Phytophthora Palmivora.
Thank you.
