How to Repair a Running Toilet – Step-by-Step Instructions

1. Identify the Problem

First, identify the cause of the running toilet. Lift the tank lid and observe the components inside. Common causes include a flapper that doesn’t seal properly, a faulty fill valve, or a loose or broken chain.

2. Adjust the Flapper

If the flapper doesn’t seal tightly, it can allow water to continuously flow into the bowl. Adjust the chain length to ensure the flapper fully closes after flushing. If the flapper is worn or damaged, replace it with a new one.

3. Check the Fill Valve

Inspect the fill valve for any issues. Ensure that the float arm and float ball move freely and aren’t obstructed. Adjust the float arm if necessary to control the water level in the tank. If the fill valve is malfunctioning, consider replacing it with a compatible replacement.

4. Examine the Overflow Tube

The overflow tube prevents the tank from overflowing. Check if the water level reaches the top of the overflow tube. If it does, adjust the fill valve to lower the water level. If the overflow tube has a crack or damage, replace it to prevent leaks.

5. Test for Leaks

After making adjustments or replacing components, test for leaks. Flush the toilet and observe if water continues to run or if there are any signs of leakage around the base, connections, or other areas. Make any necessary adjustments or repairs to ensure a watertight seal.

6. Additional Considerations

If the problem persists or if you’re unsure about performing the repairs yourself, it’s recommended to consult a professional plumber. They have the expertise to handle more complex issues or provide guidance on specific toilet models.
