Toilets can make noise on their own due to several reasons. Running water is often caused by a faulty flapper or fill valve, leading to continuous refilling. Gurgling sounds might indicate a blockage or ventilation issue in the plumbing. If you hear hissing or whistling, it could be due to high water pressure or a worn-out valve. Regular maintenance and timely repairs can prevent most of these issues, ensuring your toilet functions quietly and efficiently.
