Toilet continues to run after tank has filled.
Would RecommendA YouTube video indicated what I needed to solve the problem (flush valve seal), and Lowe's had the part in stock for a reasonable price. It was easy to install and remedied the issue. The entire flush valve assembly did not need to be replaced, only the flush valve seal; a simple and inexpensive fix.
