Clogged drains are a common occurrence, and sooner or later your household is likely to run into one. The go-to solution for such issues is to buy a chemical drain cleaner at the store, or perhaps go to the local home improvement center and purchase a plumbing snake.
In almost every instance that’s a huge mistake. Store-bought solutions rarely address the issue properly, and often force you to apply them again and again before the drain becomes clear. In most cases, if you can’t deal with the clog via a good old-fashioned plunger, it’s best to call in a professional plumber.
