The answer to 'toilet slow draining' is a slow or clogged drain is a common plumbing issue that can have several causes, such as a buildup of debris, a problem with the toilet's internal components, or an issue with the drain line. Symptoms may include water draining slowly, the toilet bowl not filling up properly, or even water backing up into the bowl.
Some potential solutions include plunging the toilet, using a drain snake or auger to clear the blockage, or checking for issues with the toilet's flapper, fill valve, or other internal parts. However, if the problem persists or you're not comfortable troubleshooting it yourself, it's best to call a professional plumber who can diagnose and fix the issue properly.
