FAQs & Answers

  1. What causes a toilet to fill with water but not flush? A toilet that fills with water but does not flush usually has a clog in the pipes or a malfunctioning flapper valve that prevents proper water flow.
  2. How can I unclog my toilet without calling a plumber? You can try using a plunger to clear the blockage. If that doesn't work, a toilet auger or snake may help remove deeper clogs. Persistent issues should be handled by a professional.
