Ghost Flushing

If your toilet’s tank auto-fills up on its own, the reason could be caused by a poorly fitting or leaky flapper or a length of a refill tube. The water in the toilet tank will be drilled gradually into your bowl when your toilet’s flapper has become worn or corroded. When the water level is to a low point within 1 – 2-hour intervals, the system activates the fill valve, and the toilet tank will be filled once more. This cycle continues and ends in what’s called ghost flushing. The toilet float can be adjusted to ensure that your toilet does not flush by itself.

How to adjust toilet float to stop running


The ideal level of water in the tank should be 1 to 2 inches below the overflow tube and fill valve. Anything higher or lower than this could cause an unbalanced level of water. Some tanks are marked by lines printed or etched into the porcelain. This is a way of indicating the proper water level. Make sure that the level is in line with the marking.


The toilet tank must be complete before beginning any adjustment. First, shut off water flow. Then, find the lever to flush or the outside valve close to the wall. Specific levers require pressing, while some will turn the valve clockwise to flush. By following the correct procedure to flush, flush the toilet to eliminate liquid from your tank.


Check the float and fill valve and the toilet tank’s float depth. In ball-and-arm systems, the float is made of plastic balls. The height of the float will determine the amount of water that will be retained by the tank. Make sure that the float is not too high or too low. It should be at the level of the water. Additionally, shake the float to see whether there’s water inside. If it is, the plastic has been damaged, and you must replace it.


Adjust the float’s height by using the screwdriver. The screw is usually placed just over the valve for filling. The clockwise or counterclockwise turn will decrease or raise the floating level. Make sure to limit the rotation to one, as any deviation from that could trigger inconsistency in flushing the toilet. Once you’re finished making the adjustments, Turn the water supply on and wait between 1 and 2 minutes to fill. Push the lever to drain the toilet. Be aware of the level of the water refill. If it is too high or low, the volume of water means that you need to repeat the procedure over again.

Running toilet float diagnosis

Before you decide the best way to reduce water waste or the low level of water in the tank of your toilet, it is essential to determine whether changing the toilet float is the answer or not. First, identify the brand of the float that your toilet is using. The majority of toilets that are old use floating devices. The fill level is generally controlled and adjusted by an adjustment screw close to the valve. If your toilet fill valve has a vertical float, it is necessary to adjust it by turning it to the side.

The continuous running of water indicates overflowing water over the tubing of the flush valve, which could result in a toilet overflow. Additionally, having too little water inside the tank can indicate that the toilet won’t flush correctly. Suppose you’re unsure about the proper amount of water your toilet requires to flush correctly. In that case, you can look here for information.

How to adjust a float

Prepare to adjust the toilet float

When you are ready to dig into your tank for your toilet, Keep a few tools in the tank, for example, a screwdriver to ensure that you can change the float and an apron to clean up any splashes of water. If you’re looking for tools, there’s nothing you need! Additionally, you’ll need to remove the tank’s lid and carefully place it onto the flooring to avoid injury, preferably with a rag or towel.

It is also advisable to examine your toilet tank to find out your float type. Various kinds of toilet floats exist, and the types vary according to the condition of the toilet. For instance, older models will likely come with the ball float that is precisely what it sounds like. It’s typically attached to a rod of metal via screws. A different kind of toilet floats is a rectangular-shaped device that moves upwards and downwards along the vertical pipe of each flush. There are various methods of altering the floats, and we’ll discuss each.

Adjusting the ball float

To adjust the ball floating device, start by removing it from the float so that it is lower than the water level. Continue to turn until it is at a point where the water ceases to flow and then turn it a half-turn. Then you can make sure the toilet is flushed and wait for the tank’s water to fill up. Verify where the water level in the tank is stalling; it should be right below the line that is the highest fill on the overflow tubing of the float. You may need to continue to lower the float to allow for the level to decrease. If this approach doesn’t solve the problem, it could mean the valve’s fault in the tank, or it may be a more significant issue.

How to modify the cylinder of toilet float

Follow steps 1 and 2 to install the ball-and-arm floating. Check inside the tank, and there’s a tiny, long tube connected by the fill valve. Most models are connected to the valve or hanging across the top. It is used to adjust the stem to increase or decrease the amount of water in the tank. Make sure you are familiar with the tank set up before starting any adjustments.

Adjust the clip for release

Locate the float’s release clips. The float on the cylinder will be adjusted by pressing the release clip to lower or raise it to the desired height. If the clip for release is not present, an alternative option to adjust the floating is to lower or raise the dial. Make sure the float is half-inch high, and then use your fingers to hold the dial near the top of the stem. Keep the stem in full rotation by turning the stem counterclockwise or clockwise to increase or decrease the height. Place the toilet’s lid in place when you reach the correct height.

You should not exceed one full rotation as in ball-and-arm floating. Switch the water supply back on, and give it 1 to 2 minutes for the water to fill. The lever should be pushed for flushing the toilet. Be aware of the level of the water refill. A too high or low volume of water will mean you require adjusting the float until you reach the right height.


Knowing how to adjust toilet float to stop running will allow you to avoid issues with flushing and the drenching of your toilet. It can also make a massive difference in money that could otherwise have gone into the pockets of handymen. Although it’s simple to alter the toilet floats, you must be aware of your toilet’s kind of float. This will allow you to follow the proper method and resolve your excessive or water shortage issues. Now that you can adjust your toilet’s float yourself, What do you think about telling other people who may be having issues keeping your toilet tank level?
