The small overflow hole near the top of a sink is a safety feature that drains water if the sink overfills, and it also lets air into the drain. When it clogs, the sink drains slower and smells can build up.
The job
The overflow connects to the drain below the stopper, so it lets air in and gives excess water an escape path.
The clog
Soap, toothpaste, and mineral scale build up in the overflow channel, and the sink drains slowly or gurgles.
The cleaning
A small brush and hot water, or a gentle cleaner, clears the channel. A wet-dry vacuum can also pull the gunk out.
The deeper issue
If the overflow is clear but the sink still drains slow, the clog is in the drain itself. mineral-rich water varies by region, and older neighborhoods still run on aging galvanized or copper lines In San Jacinto, hard water scale makes overflow clogs more common.
The clean
A small brush and hot water clear the overflow channel, and a wet-dry vacuum can pull the gunk out fast. It also improves the drain's airflow.
