Replace a broken toilet float

Replacing a broken toilet float is a straightforward task that ensures your toilet refills and shuts off properly. Here's a step-by-step guide:

1. Gather Tools and Materials

• Adjustable wrench or pliers

• Replacement toilet float or fill valve (ensure compatibility with your toilet model)

• Sponge or towel (for any water spills)

  
  

2. Turn Off the Water Supply

1. Locate the shut-off valve behind or near the toilet and turn it clockwise to close.

2. Flush the toilet to drain as much water as possible from the tank.

3. Use a sponge or towel to soak up any remaining water in the tank.

   
   

3. Remove the Old Float

1. Identify the float type:

   • Older toilets may have a float ball connected to an arm.

   • Modern toilets often use a fill valve with an integrated float mechanism.

2. Disconnect the float assembly:

   • For a float ball:

     • Unscrew the ball from the float arm.

     • If the arm is broken, remove it by unscrewing it from the fill valve.

   • For an integrated float:

     • Disconnect the water supply line from the fill valve using pliers or a wrench.

     • Unscrew the locking nut underneath the tank to remove the entire fill valve assembly.

       
       

4. Install the New Float

1. Position the new fill valve or float assembly:

   • Insert the new fill valve into the hole at the bottom of the tank.

   • Adjust the height of the fill valve (if adjustable) to match the waterline in the tank.

2. Secure the fill valve:

   • Tighten the locking nut underneath the tank by hand and then give it a final turn with a wrench. Avoid overtightening to prevent cracks.

3. Reattach the water supply line:

   • Connect the supply line to the fill valve and tighten securely.

     
     

5. Test the Float

1. Turn the water back on:

   • Slowly open the shut-off valve to fill the tank.

2. Adjust the float level:

   • For a float ball:

     • Bend the arm gently up or down to set the water level.

   • For an integrated float:

     • Use the adjustment screw or clip to raise or lower the float to the desired water level (usually marked inside the tank).

3. Check for leaks:

   • Inspect the connections and tank base to ensure there are no leaks.

     
     

6. Final Check

• Flush the toilet a few times to ensure the float operates smoothly and stops water flow at the correct level.

  
  

Tips

• Compatibility: Bring the old float or fill valve to the hardware store to find a suitable replacement.

• Water level adjustment: Ensure the float shuts off the water below the top of the overflow tube to prevent continuous running.

• Clean the area: Take the opportunity to clean sediment or debris from the tank.
