Sewage and other debris tend to accumulate in both sewer lines and in main lines leading to septic tanks. This is a common problem in both old and newer homes, as modern water saving toilets do a poor job of pushing waste out of sewage lines. This troublesome organic build-up can quickly result in clogging problems and back-ups. Roebic's K-97 main line cleaner attacks this accumulated material and quickly restores proper flow, keeping your lines problem free.
