Roebic K-97 Main Line Cleaner - 1 Quart

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. Use in every household, whether on a septic system or city sewers. Ideal for ``low flow" water saver toilets and undersized septic tanks that are overworked. Safe for pipes and the environment. One bottle, twice a year, will keep the main line free of unwanted build-up and prevent back-ups during heavy water use.
