A drain hole is an opening designed to allow water or other liquids to escape from a particular area. It is commonly found in various settings, such as sinks, bathtubs, and outdoor spaces, to prevent water accumulation. The size and location of a drain hole can vary depending on its intended use and the volume of liquid it needs to handle. In construction and plumbing, drain holes are essential for maintaining proper drainage and preventing water damage. They are often connected to a drainage system that channels excess water away from buildings and structures, ensuring safety and longevity. Proper maintenance of drain holes is crucial to avoid clogs and flooding.
