Why Does a Toilet Keep Running?
A toilet that continues to run after flushing usually means that something in the tank isn’t functioning correctly. Here are the most common causes:
- Worn-out flapper
- Misaligned or overly tight flush chain
- Faulty or dirty fill valve
- Float that is incorrectly set
- Cracks in the overflow tube
- Corrosion on the flush valve seat
Understanding how these parts interact helps you quickly diagnose and fix the issue.
Step 1: Turn Off the Water Supply
Before starting any repairs, shut off the water supply to your toilet. You’ll find a shutoff valve near the base of the toilet on the wall. Turn it clockwise to stop the water flow.
Flush the toilet to drain the tank completely before proceeding.
Step 2: Inspect and Replace the Toilet Flapper
The flapper is a rubber seal at the bottom of the tank. If it’s cracked, warped, or not sealing correctly, water will continuously leak into the bowl.
How to replace the flapper:
- Remove the tank lid
- Unhook the chain from the flush handle
- Remove the old flapper from the flush valve
- Bring it to a hardware store to find an exact replacement
- Clean the flush valve seat
- Install the new flapper and reconnect the chain
- Make sure the chain has just enough slack
- Turn the water supply back on and test the flush
This is one of the easiest and most effective ways to perform a slow running toilet fix.

Step 3: Adjust the Chain and Float
If the flapper is fine but the toilet still runs, the issue might be with the chain or the float mechanism.
Chain Adjustment:
- Check that the chain isn’t too tight or too loose
- Adjust the clip or remove links if needed
Float Adjustment:
- If using a float arm, bend it gently downward
- If using a float cup, slide it down along the fill valve
- Aim to have the water level sit about one inch below the top of the overflow tube
This helps regulate the refill level and prevent unnecessary water waste.
Step 4: Clean or Replace the Fill Valve
The fill valve controls how much water enters the tank. Stop the Leak: Easy Fixes for a Constantly Running Toilet Running Toilet Repair Made Easy Guide If it’s clogged or broken, the tank may never stop filling.
To clean the fill valve:
- Shut off water and flush
- Remove the valve cap
- Cover with a cup and briefly turn on water to flush debris
- Clean any mineral buildup with a brush
- Reassemble and test
If cleaning doesn’t work, replace the fill valve:
- Disconnect the water line
- Remove the lock nut underneath the tank
- Remove the old fill valve and insert a new one
- Reattach the water line and test
- Adjust water level as needed
This is a crucial step in completing a water running toilet fix.
Step 5: Check the Overflow Tube and Flush Valve Seat
Overflow Tube:
- Ensure the water level is below the top of the tube
- Replace the tube if it has cracks or damage
- Adjust the float to lower the water level if needed
Flush Valve Seat:
- Inspect for signs of corrosion or debris
- Clean lightly with a scouring pad
- Replace the entire flush valve assembly if needed
If your toilet continues running after all other repairs, these parts are worth examining.

Preventive Maintenance Tips
Prevent future running toilet issues by keeping your toilet components in good condition:
- Avoid using bleach tablets or harsh chemical cleaners
- Clean your tank annually to prevent mineral buildup
- Replace rubber components at the first sign of wear
- Check float and chain positions every few months
Staying ahead of these issues helps your toilet last longer and saves water.
