Drainage accessories are components that enhance the efficiency and functionality of drainage systems. These include items like drain covers, grates, and pipes that help manage water flow and prevent blockages. They are essential for directing excess water away from structures, reducing the risk of flooding and water damage. Additionally, drainage accessories can include sump pumps, which remove accumulated water from basements, and downspout extensions, which direct rainwater away from foundations. Proper installation and maintenance of these accessories are crucial for ensuring effective drainage and protecting property from water-related issues.
