Sewer Dye comes in two primary forms, tablets and powder. Powdered Sewer Dye should be used when tracing lines over 200 feet in length. Mix powder dye with water in a jet container and squirt the desired amount in the sewer line.
Dye tablets just require the operator to drop a tablet into the sewer pipe, and the dye will trace the water path. Dyes are available in three different colors: Red, Blue and Yellow/Green.
