- SHAKE WELL BEFORE USING
- FOR SEPTIC TANKS: Rate (20oz per 1000-gal tank). Pour directly into drains closest to the tank or in problem drains. Best applied at night or low use times, allowing dwell time. Dose. 8-16oz every 4 weeks for maintenance. Increase/decrease dosage for desired results.
- FOR SLOW DRAINS, DISPOSALS & SEWER: Apply at a rate of twice the diameter of the drain, 4" drain = 8oz solution; 8" drain = 16oz. Allow dwell time prior to flushing. Excellent for FOG (fats, oils, grease) programs!
- FOR RV AND HOUSEBOAT HOLDING TANKS: 2oz per gallon of greywater (tank). 2-4oz for each drain preventing dry trap and for long term storage. Beneficial for dump stations too!
- FOR LAGOONS, LIFT STATIONS AND GREASE TRAPS: 2 gal. per 1 million gal. of water or average bi-weekly flow, continuing treatment of 2 gal. every day until desired results. Can be used in preventative maintenance pump program.

It really works wonders! I had a slow drain problem and it cleared and cleaned it up.
This stuff is amazing! Our drain system is 50 years old & when it starts to drain slow I just add a cup at nite & by morning it just fine 🤗
Absolutely love this product! It cleared my drain in no time.
Noticed a significant improvement in septic system efficiency. Will buy again.
Good, but took two applications for the desired effect. Overall, satisfied.
