Drain maintenance involves regular inspection and cleaning of drainage systems to ensure they function properly. This process helps prevent blockages caused by debris, grease, or tree roots, which can lead to water damage and costly repairs. Routine maintenance can include using tools like drain snakes or high-pressure water jets to clear clogs. Homeowners may also benefit from scheduling professional services to assess the condition of their drainage systems and make necessary repairs, ensuring efficient water flow and reducing the risk of flooding.
