Common Causes of Running Toilets

A running toilet is usually caused by a flapper that won't seal, a chain that's too long or short, or a fill valve that won't shut off properly.

Quick Diagnostic Steps

  1. Remove the toilet tank lid and look inside
  2. Check if the flapper is sealing properly over the flush valve
  3. Ensure the chain connecting the flush handle to the flapper has slight slack
  4. Verify the water level isn't too high

Step-by-Step Solutions

Fix #1: Adjust the Flapper

  1. Turn off water supply to the toilet
  2. Flush to empty the tank
  3. Clean around the flapper seat
  4. Ensure the flapper sits flat and centered
  5. Replace flapper if warped or cracked

Fix #2: Adjust the Chain

  1. The chain should have about 1/2 inch of slack
  2. Too tight: flapper won't seal properly
  3. Too loose: flapper won't lift when flushed
  4. Adjust chain length by moving it to different holes in the flapper

Fix #3: Adjust Water Level

  1. Water level should be about 1 inch below the rim of the tank
  2. Bend the float arm to adjust water level
  3. Or adjust the screw on newer fill valves
