Since I bought a good distiller,and double distill tap water,I find it just 
about impossible to get yellow ,brown or any  sediment.When I was buying DW 
from the store,I had to watch it like a hawk as it would run away and go yellow 
or brown with plating on the inside of the jar.I always had to filter it as 
there were floaters,etc.Now,I can go away;[it runs at 1ma of current];for 
hours, except for an occasional check to clean the silver coins,and reverse the 
polarity .
