If your toilet is running every few minutes and it's not the flapper, the issue might be with the fill valve or the float. Check if the float is set too high or if it’s damaged, causing excess water to overflow into the tube. Alternatively, inspect the fill valve; it could be malfunctioning or need adjustment. Replacing or adjusting these parts can solve the problem.

FAQs & Answers

  1. What causes a toilet to run if the flapper is not the problem? A running toilet with no flapper issues is often caused by a faulty fill valve or a misadjusted or damaged float allowing water to overflow into the overflow tube.
  2. How can I fix a toilet that keeps running due to the fill valve? You can fix a running toilet by adjusting or replacing the fill valve, and ensuring the float is set correctly to stop water from continuously filling.
  3. How do I adjust the float in my toilet tank? Adjust the float by either bending the float arm or sliding the float up or down on the rod, depending on the type, to control when the fill valve shuts off.
  4. When should I replace my toilet’s fill valve? Replace the fill valve if adjusting it does not stop the toilet from running or if you notice it is malfunctioning or damaged.
