Are dissolving liquid drain openers (like Draino or Liquid Plumber) harmful to pipes?
Draino and like product are adequate for minor clogs, but do not overuse them and never use them on a completely clogged drain. The corrosive ingredients will be trapped in your pipes, which can severely damage them. For any severely drained clog we definitely recommend you to contact us to do so. Also, never use dissolving drain openers in a drain that has a garbage disposal.
