Hi, I am just setting up my organic garden and want to set up a drip line or soaker hose, but don't want to use the standard rubber recycled or plastic materials since they are not NSF-61 standards healthy for potable water. I have clean water from a well to the spigot, and don't wish to contaminate the water through the dripline/soaker hose. There is a standard for potable water called NSF-61 and I wish to only use products that meet that standard. Does anyone know of any dripline or soakerhose products that meet this standard? Thanks for any recommendations!
