Biodegradable, Odorless & Nonflammable Caustic Drain Opener
Ensure Caustic Drain Opener is a fast-acting, safer caustic drain opener formulated to provide the performance of traditional caustic drain openers while being biodegradable, odorless, and nonflammable. Its high-density, thickened formula is heavier than water, allowing it to sink and cling to blockages where it begins working quickly.
For Sewer Mains: Pour 2–4 gallons into the manhole or into the upstream drain, as close to the obstruction as possible. For best results, use regularly to keep the sewer main open and free-flowing.
For Laterals: Pour 1 gallon into the drain upstream and as close to the obstruction as possible.
For Drains: Slowly pour ½–1 quart into the drain and allow to work for 30 minutes. For difficult obstructions, a second application may be necessary. Where there is a history of obstructions, regular use at weekly intervals—or more frequently if required—will help keep the line open and free flowing.
