What is a common symptom of a clogged drain?

A common symptom of a clogged drain includes a range of indicators that suggest restricted water flow. Low water flow occurs when the drain is partially blocked, making it difficult for water to pass through efficiently. Unusual odors can arise from stagnant water or decomposing food particles trapped within the clog, contributing to unpleasant smells. Gurgling sounds typically signal that air is being trapped in the drainage system due to the blockage, creating bubbling or gurgling noises as water struggles to move past the obstruction.

Each of these symptoms reflects different aspects of how a clogged drain can manifest, and thus, "all of the above" accurately encompasses the collective signs of a clogged drain scenario. Recognizing these symptoms can help prompt timely intervention to prevent further plumbing issues.
