Troubleshoot: Why Is My Swiss Madison Toilet Float Not Shutting Off?

A malfunctioning toilet float can be a major annoyance, leading to constant water running and increased water bills. If you’re experiencing this issue with your Swiss Madison toilet, don’t worry—you’re not alone. In this comprehensive guide, we’ll explore the potential causes of this problem and provide step-by-step instructions on how to fix it.

Causes of a Swiss Madison Toilet Float Not Shutting Off

• Incorrect Float Adjustment: The float is responsible for regulating the water level in the tank. If it’s not properly adjusted, it may not shut off the water supply when the tank is full.
• Damaged Float: Over time, the float can become damaged or worn, preventing it from functioning correctly.
• Faulty Fill Valve: The fill valve is connected to the float and controls the flow of water into the tank. A faulty fill valve can cause the float to malfunction.
• Debris or Scale Buildup: Debris or scale buildup on the float or fill valve can interfere with their operation.
• Worn Flapper Valve: The flapper valve is located at the bottom of the tank and seals the drain hole. A worn flapper valve can allow water to leak into the bowl, causing the float to rise and not shut off.
• High Water Pressure: Excessive water pressure can cause the float to rise too quickly, preventing it from shutting off the water supply.
• Loose or Broken Flush Valve: A loose or broken flush valve can allow water to leak into the bowl, which can trigger the float to rise and not shut off.

Troubleshooting and Repair Steps

1. Check the Float Adjustment:

• Remove the tank lid and locate the float.
• Adjust the float by bending the arm that connects it to the fill valve.
• Adjust the float so that it’s about 1 inch below the overflow tube.

2. Inspect the Float:

• Examine the float for any damage or wear.
• If the float is damaged, replace it with a new one.

3. Test the Fill Valve:

• Turn off the water supply to the toilet.
• Flush the toilet to drain the tank.
• Turn the water supply back on and observe the fill valve.
• If the fill valve doesn’t stop filling the tank after a few minutes, it’s likely faulty and needs to be replaced.

4. Clean Debris or Scale Buildup:

• Remove the float and fill valve.
• Clean any debris or scale buildup from the float, fill valve, and tank.
• Reinstall the float and fill valve.

5. Replace the Flapper Valve:

• Remove the old flapper valve.
• Install a new flapper valve according to the manufacturer’s instructions.

6. Check Water Pressure:

• Contact your local water utility to inquire about the water pressure in your area.
• If the water pressure is too high, install a water pressure regulator to reduce it.

7. Tighten or Replace the Flush Valve:

• Tighten the bolts that secure the flush valve to the tank.
• If the flush valve is damaged or broken, replace it with a new one.
