Why Is My Duravit Toilets Float Not Shutting Off? The Possible Reasons & Solutions

A malfunctioning toilet float can lead to a persistent flow of water, wasting precious resources and driving up utility bills. If you’re experiencing this issue with your Duravit toilet, don’t panic! Here’s a comprehensive guide to help you identify and fix the problem quickly and effectively.

Causes of a Float Not Shutting Off

• Broken or Misaligned Float Arm: The float arm is a lever that connects the float to the fill valve. A broken or misaligned float arm can prevent the float from rising high enough to shut off the water flow.
• Defective Float: The float itself can become damaged or waterlogged, losing its buoyancy and failing to shut off the water.
• Clogged Fill Valve: Sediment or debris can accumulate in the fill valve, preventing it from closing properly.
• Faulty Flapper Valve: The flapper valve is a rubber seal that prevents water from leaking from the tank into the bowl. A faulty flapper valve can allow water to escape, causing the float to rise and shut off the water prematurely.
• High Water Pressure: Excessive water pressure can overcome the float’s resistance and keep it from rising high enough to shut off the water.

How to Fix a Float Not Shutting Off

1. Check the Float Arm

• Inspect the float arm for any damage or misalignment.
• Gently bend the arm up or down as needed to ensure that it’s parallel to the tank’s side.

2. Replace the Float

• If the float is damaged or waterlogged, it needs to be replaced.
• Turn off the water supply to the toilet and disconnect the fill valve.
• Unscrew the old float and replace it with a new one.

3. Clean the Fill Valve

• Remove the fill valve from the tank and disassemble it.
• Clean the valve seat and diaphragm using a soft brush or cloth.
• Reassemble the fill valve and reinstall it in the tank.

4. Inspect the Flapper Valve

• Check the flapper valve for any damage or wear.
• If the flapper is damaged, replace it with a new one.
• Ensure that the flapper is properly seated on the flush valve.

5. Adjust the Water Pressure

• If the water pressure is too high, it may be necessary to install a pressure regulator.
• Contact a licensed plumber to have the water pressure checked and adjusted.

Additional Tips

• Use a water-saving toilet to reduce water consumption.
• Regularly inspect and clean your toilet to prevent future problems.
• If you’re unsure about any of the above steps, don’t hesitate to call a professional plumber for assistance.
