A drain assembly is a system of components designed to remove excess water from a specific area, such as sinks, bathtubs, or showers. It typically includes a drain, a trap, and connecting pipes that direct wastewater away from the fixture and into the plumbing system. These assemblies are essential for preventing water buildup and ensuring proper drainage. They often feature a strainer or cover to catch debris, which helps maintain the flow of water and prevents clogs in the plumbing. Regular maintenance of drain assemblies can help avoid costly plumbing issues.
