What Customers Are Saying

Customers praise this drain cleaner for effectively clearing slow or moderately clogged kitchen and bathroom drains, with many reporting success on weak toilet flushing and gurgling sounds when used as directed. Reviewers highlight its ease of use and value as preventive maintenance for recurring drainage issues. However, a notable group finds it ineffective on severe main line or sewer clogs, sometimes requiring professional plumbing intervention. A few report product integrity concerns. Overall, most customers consider it reliable for minor to moderate blockages but not suitable for major plumbing problems.

Did an excellent job clearing the line out to the sewer. I am buying another to have on hand if the line clogs again.
