One of the most common reasons for a kitchen sink to stop working is a clogged drain. Over time, food particles, grease, and other debris can build up in the drain and cause it to become blocked. This can lead to slow draining or even a complete blockage, making it difficult or impossible to use your sink. If you notice that your sink is draining slowly or not at all, it is important to address the issue immediately to prevent further damage. You can try using a plunger or a drain snake to clear the clog, but if these methods don't work, it may be time to call a professional plumber.1. Clogged Drain
