What is the difference between a clogged drain and a slow drain?

A clogged drain is typically a complete blockage that prevents any water from passing through, often resulting in standing water in a sink, tub, or floor drain. A slow drain, on the other hand, still allows water to pass but at a significantly reduced rate. While both are signs of obstruction, a slow drain is usually the result of partial buildup from hair, soap scum, food particles, or grease. It may also signal the early stages of a more serious clog. At WaterWorks, we investigate the cause of the blockage using both visual inspection and, when necessary, diagnostic tools like drain cameras. Understanding whether a drain is fully clogged or simply draining slowly helps us choose the safest and most effective clearing method. We always aim to address the issue at its source to avoid repeat problems.
