Slow Draining Water One of the most common signs of a blocked drain is slow-draining water. If you notice that your kitchen sink, shower, or bathtub is taking longer than usual to empty, something is likely clogging the pipes. In kitchens, grease or food particles are often the cause, while hair and soap buildup are typical in bathroom drains. If a quick plunge doesn’t clear the blockage, it’s time to call an expert.
