Need to know how to fix a running toilet ball float fast? – Skip down to the part where we talk about replacing a damaged or worn out ball float.
A running toilet can be an annoying and wasteful problem to deal with, but it’s essential to fix it as soon as possible.
One common cause of a running toilet is an issue with the ball float or float ball mechanism.
In this article, we’ll guide you through how to diagnose, and how to fix a running toilet ball float.
Understanding the Ball Float Mechanism
The ball float, also known as the float ball, is part of the ballcock supply valve assembly. It’s responsible for controlling the water level in the toilet tank.
If the ball float mechanism is damaged or not functioning properly, it can lead to a running toilet.
Common issues with the ball float mechanism include corrosion, a bent or broken float rod, and a float ball that’s no longer buoyant.
Diagnosing Ball Float Problems
To determine if the ball float is causing the running toilet, you’ll need to inspect it and its components.
Check the ballcock supply valve for signs of corrosion, and examine the float rod for any bends or breaks. Additionally, make sure the float ball is still buoyant and not waterlogged.
Step-by-Step Guide to Fixing a Running Toilet Ball Float
Here’s how to fix a running toilet caused by ball float issues:
Adjusting the Ball Float Arm
- If the float rod is bent, gently bend it back into shape to change the water level in the tank. Make sure to do this with care, applying gentle pressure to avoid snapping the rod. Adjusting the float rod’s angle can help to fine-tune the water level, ensuring that the toilet flushes properly and doesn’t run continuously.
- Ensure the ball float is positioned correctly so it doesn’t interfere with any other components in the tank. The float ball should be free to move up and down without touching the tank’s walls, the flush valve, or any other parts. If necessary, adjust the length of the float rod or slightly bend it to create more clearance, allowing the float ball to function without obstruction. This ensures that the ball float can accurately regulate the water level in the tank and prevent overfilling or running issues.
Replacing a Damaged or Worn-Out Ball Float
- Turn off the water supply valve, remove the tank’s lid, and flush the toilet to empty the tank.
- Place a small plastic bin under the ballcock supply valve shank to catch excess water, and unscrew the hose from the base of the tank.
- Using an adjustable wrench or rib joint pliers, unscrew the lock nut located at the bottom of the ball supply valve shank.
- Remove the entire assembly from the tank and place it into the bin to drain any remaining water.
- Purchase a new ball supply valve assembly kit from a hardware or plumbing supply store. This kit should include the valve assembly with float ball, connecting rod, and plastic fill tube.
- Slide the tank gasket fully onto the shank of the new ball supply valve, and adjust its height to best suit the height of the tank, usually around 1/2 inch below the edge of the tank and aligned with the overflow tube.
- Insert the threaded end of the new assembly into the hole where the old assembly was removed, and secure it with the lock nut.
- Reattach the water supply hose to the ballcock supply valve shank and connect the fill hose to the overflow tube.
- Turn on the water supply valve to fill the tank, and make any necessary adjustments to the water level by twisting the screw at the top of the ballcock assembly.
Preventive Measures and Maintenance
To avoid future issues with your ball float, follow these tips:
- Regularly inspect the ball float and other toilet components for signs of wear, damage, or corrosion.
- Keep the toilet tank clean and free of debris that could interfere with the ball float’s function.
- Consider upgrading to a more modern fill valve system, which can offer improved performance and take up less space in the tank.
