Fix a toilet that intermittently flushes by checking the flapper valve in the tank. Make sure it's sealing properly. If it's warped or damaged, replace it. Inspect the chain connected to the flapper; it should have some slack but not be tangled. Check the fill valve for proper water level settings. Adjust the float if necessary. If these steps don't work, you might need a new flush valve assembly.

FAQs & Answers

  1. Why does my toilet flush intermittently? Intermittent flushing usually happens due to a faulty flapper valve that doesn’t seal properly, incorrect chain length, or improper water level settings in the tank.
  2. How do I know if the flapper valve needs to be replaced? If the flapper valve is warped, cracked, or doesn’t create a tight seal causing water to leak from the tank, it should be replaced.
  3. Can adjusting the fill valve fix flushing problems? Yes, adjusting the fill valve or float to ensure the correct water level in the tank can often resolve intermittent flushing issues.
