Why Is My Cotto Toilet Float Not Shutting Off? Here’s The Fix!

In a well-functioning toilet, the float is a crucial component that regulates the water level in the tank. When the water level rises, the float ascends and triggers the fill valve to close, stopping the flow of water. However, if the float fails to shut off, it can lead to a constantly running toilet, wasting water and increasing your utility bills.

Causes of a Float Not Shutting Off

There are several reasons why a cotto toilet‘s float may not be shutting off properly:

1. Worn or Damaged Float:

Over time, the float can become worn or damaged, causing it to lose buoyancy. This can prevent it from rising to the correct level, resulting in the fill valve remaining open.

2. Incorrect Float Adjustment:

The float is typically adjustable to accommodate different water levels. If the float is set too high, it may not reach the shut-off point before the tank is full. Conversely, if it’s set too low, it may shut off prematurely, causing the toilet to flush prematurely.

3. Float Arm Interference:

The float arm, which connects the float to the fill valve, can become bent or obstructed, preventing the float from moving freely. This can hinder the float’s ability to shut off the water.

4. Clogged Fill Valve:

The fill valve itself may be clogged with debris or mineral deposits, preventing it from closing properly even when the float is in the correct position.

5. Broken Fill Valve:

In some cases, the fill valve may be broken or malfunctioning, causing it to remain open regardless of the float’s position.

Troubleshooting and Solutions

1. Check the Float:

Inspect the float for any visible damage or wear. If it appears damaged, replace it with a new one.

2. Adjust the Float:

Locate the adjustment screw on the float arm and adjust the float to the correct level. Typically, the float should shut off the water when it reaches the top of the overflow tube.

3. Inspect the Float Arm:

Ensure that the float arm is not bent or obstructed. If necessary, gently bend it back into place or remove any obstructions.

4. Clean the Fill Valve:

Remove the fill valve and clean it thoroughly with vinegar or a commercial cleaning solution. Remove any debris or mineral deposits that may be clogging the valve.

5. Replace the Fill Valve:

If cleaning the fill valve doesn’t resolve the issue, it may need to be replaced. Purchase a new fill valve that is compatible with your cotto toilet.

Preventative Measures

To prevent future issues with the float not shutting off:

• Regularly inspect and clean the toilet tank and components.
• Adjust the float level as needed to ensure proper water level.
• Avoid flushing non-biodegradable items that can clog the fill valve.
• Use a water softener to reduce mineral buildup in the toilet tank.

Wrapping Up

If your cotto toilet’s float is not shutting off properly, it’s important to address the issue promptly to avoid water waste and higher utility bills. By following the troubleshooting steps outlined above, you can identify the cause of the problem and implement the appropriate solution. If the issue persists or you are unsure of how to proceed, consult a qualified plumber for assistance.
