How to fix a running toilet ?


  • Identify the Problem:

Lift the toilet tank lid and observe what’s happening. Look for any obvious issues like water continuously running into the overflow tube or a malfunctioning flapper.


  • Check the Float:

Ensure the float is not too high, causing the water level to rise above the overflow tube. If it is, adjust the float level according to the manufacturer’s instructions.


  • Inspect the Flapper:

Check the flapper valve. If it’s worn or not sealing properly, water may be continuously leaking into the bowl. Replace the flapper if necessary. Make sure the chain connecting the flush handle to the flapper is appropriately adjusted—not too tight or too loose.


  • Adjust the Water Level:

Adjust the water level in the tank. Most toilets have a water level mark inside the tank. It’s typically marked on the overflow tube. Adjust the fill valve or float to set the water level to the marked line.


  • Check for Leaks:

Look for any leaks around the base of the toilet or in the tank. If you notice water on the floor, it may indicate a faulty wax ring or a loose connection.


  • Clean or Replace the Fill Valve:

Sediment and debris can accumulate in the fill valve, affecting its performance. Turn off the water supply, flush the toilet to empty the tank, and clean the fill valve. If the fill valve is old or damaged, consider replacing it.


  • Inspect the Overflow Tube:

Ensure the overflow tube is not damaged or misaligned. If water is continuously flowing into it, it can cause a running toilet. Adjust or replace the overflow tube if necessary.


  • Check for a Faulty Flapper Seal:

If the flapper isn’t sealing properly, it can lead to a running toilet. Clean the flapper and the seat it covers. If the flapper is damaged or warped, consider replacing it.


  • Examine the Flush Handle:

Make sure the flush handle is properly connected to the lift arm and chain. Adjust or replace it if needed.


  • Turn Off the Water Supply:

If the issue persists, turn off the water supply to the toilet. This can prevent water waste and potential damage while you address the problem.



If you’re unsure or uncomfortable performing these tasks, or if the problem persists after attempting these fixes. it’s advisable to consult with a professional plumber for further assistance. They can diagnose and address more complex issues and ensure that your toilet is functioning properly.
