We’ve created a step-by-step flowchart to help you troubleshoot and fix the problem. Follow along to identify the cause of your toilet running and take the necessary steps to resolve it.

6 Signs Your Toilet Running

Step 1: Identify the Problem

Question: Is water constantly flowing into the toilet bowl?

  • Yes: Proceed to Step 2.
  • No: If the toilet occasionally runs, it might be due to a flapper not sealing properly. Skip to Step 4.

Step 2: Check the Flapper

Question: Is the flapper properly covering the flush valve opening?

  • Yes: Proceed to Step 3.
  • No: Adjust or replace the flapper to ensure a tight seal. If the problem persists, move to Step 3.

Step 3: Inspect the Fill Valve and Float

Question: Is the float sitting at the proper water level, and is the fill valve functioning correctly?

  • Yes: The issue might be with the overflow tube. Move to Step 4.
  • No: Adjust the float to the correct water level or replace the fill valve if it’s malfunctioning.

Step 4: Check the Overflow Tube

Question: Is the water level reaching the top of the overflow tube?

  • Yes: The problem might be the water level adjustment or a faulty flapper. Move to Step 2 to address those issues.
  • No: Proceed to Step 5.

Step 5: Check the Flush Handle and Chain

Question: Is the chain attached properly and allows the flapper to close fully?

  • Yes: Proceed to Step 6.
  • No: Adjust the chain length so the flapper can close without slack.

Step 6: Test the Fill Valve Adjustment

Question: Does adjusting the fill valve resolve the issue?

  • Yes: Congratulations! Your running toilet is fixed.
  • No: If the problem persists, it might be time to consider professional assistance, as there could be more complex underlying issues.
