The answer to 'toilet not working' is that there are several common causes, including a clogged toilet, a broken flapper, or issues with the fill valve or flush valve. Symptoms may include the toilet not flushing properly, water not refilling the tank, or the toilet continuously running.
For minor issues, homeowners can often fix the problem themselves by plunging the toilet, replacing the flapper, or adjusting the fill valve. However, for more complex problems like a cracked toilet or issues with the plumbing, it's best to call a professional plumber to diagnose and repair the issue.
