This helps ensure it is functioning properly and prevents issues like clogs, backups, and erosion. Proper drainage is essential for protecting your home's foundation and landscaping from water damage.
During a yearly inspection, you should check for any blockages in the drains, gutters, or downspouts, and clear out any debris or vegetation growth.
