Are caustic liquid drain openers such as Drano harmful to pipes?
A. For minor clogs, they are fine, but never use them on a drain that is completely clogged. The caustic ingredients are trapped in your pipes, and it can severely damage them. If you cannot snake the drain yourself, contact a professional to do so. Never use caustic drain openers in a drain that has a garbage disposal. You can count on Murley Plumbing to take care of all your clogged drains.
