Sink Drains Slowly? Why It Happens and How to Fix It for Good
A sink that drains slowly rarely fixes itself. The clog is building, and the longer you wait, the more likely you end up with a full backup. Here is what is usually going on and what to do.
Bathroom sinks: hair and soap scum
Hair wraps around the pop-up stopper and soap binds it into a mat. Remove the stopper, pull out the hair, and flush with hot water. Avoid chemical drain cleaners — they damage pipes and rarely remove the whole clog.
Kitchen sinks: grease and food
Grease goes down warm and liquid, then cools and hardens on the pipe walls. Over months the pipe narrows until a slow drain becomes a blocked one. A plunger may help temporarily, but the buildup remains.
Multiple slow drains: a bigger problem
If more than one drain is slow, or you hear gurgling when the toilet flushes, the blockage is likely in a branch or main line. That points to roots, a belly in the pipe, or sewer trouble — see our sewer camera inspection page.
Professional fixes
- Drain cleaning with a cable machine clears the clog quickly.
- Hydro jetting scrubs grease and scale off the entire pipe wall so clogs stop returning.
- Camera inspection confirms the pipe is clear and healthy.
