If you live in a home with a septic system, you’ve likely been warned to watch what goes down your drains. So when a stubborn clog strikes, it’s tempting to reach for a trusted chemical drain cleaner like Drano. But before you pour, ask yourself: Is Drano safe for septic tanks?

Drano and similar chemical drain cleaners (like Liquid-Plumr) work by generating intense heat and using harsh chemicals—typically sodium hydroxide (lye) or sulfuric acid—to essentially burn through or dissolve the organic matter causing a clog.

According to S.C. Johnson (the makers of Drano), their products are safe for plastic and metal pipes and "will not harm" a septic system when used as directed. They argue that the chemical becomes diluted enough by the time it reaches the tank that it won't cause a total bacterial die-off.
