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.



For over 50 years Roebic has developed high quality products engineered for optimum performance targeting specific problems and troublesome areas within the septic system. Trust Roebic, The Septic Professionals, for all you septic and drain care needs.

K-97 Main Line Cleaner is a concentrated bacterial waste-degrading product designed to clean main sewer pipes of fats, grease, sludge and paper without the use of harsh aggressive and dangerous chemicals. It contains millions of specialized waste degrading bacteria the effectively reduce sewage build-up in main waste lines.

K-97 Main Line Cleaner is ideal for the undersized septic tank that is currently "OVERWORKED"; K-97 Main Line Cleaner used weekly will assure a constant level of active waste degrading bacteria for maximum bacterial action under severe conditions.

K-97 should be used in EVERY household, whether on a septic system or city sewers.  One bottle, twice a year, will keep the main line free of unwanted build-up and prevent back-ups during heavy water use

K-97 Main Line Cleaner. Sewage solids and other organic debris can accumulate in both sewer lines and in the "Main" line which exits your house; and can lead to sluggish flushing or even messy back ups. The use of "low flow" toilets has made this common problem even worse. K-97 is formulated with our patented waste degrading bacteria to powerfully and effectively digest accumulated sewage build-up. Regular use of our K-97 will help keep this problem under control by keeping sewer and main lines draining quickly and effectively.
