Sanco Industries Root Destroyer - 2 Pounds (32 Ounces) - Copper Sulfate Pentahydrate

i had a tree removed and they left the stump. Will this product remove the stump?

How many applications of this product do you do to kill roots in your septic line?

is it okay to use on old clay sewer pipes?

my root clog was about 80 FEET from the floor drain... almost to the tap.. will this be effect on material that far from the initial insertion point?
