A clogged basement drain presents several telltale symptoms, including slow drainage or standing water, often accompanied by a foul, musty odor that signals stagnant water and potential mold growth. You might notice water backing up into the basement, creating puddles or damp spots on the floor. In more severe cases, there could be visible debris or sediment around the drain, indicating a blockage. Additionally, an unexpected increase in humidity levels and persistent water stains on walls and floors are common indicators. If left unchecked, a clogged drain can lead to extensive water damage and structural issues.
