Why does my toilet keep overflowing and how can I prevent it from happening in the future?

Your toilet may be overflowing due to a clog in the pipes or a malfunctioning float valve. To prevent it from happening in the future, avoid flushing large amounts of toilet paper or foreign objects. Regularly maintain your toilet by checking for leaks and ensuring proper water levels. If the issue persists, consider contacting a plumber for further assistance.
