How to Get More Water in Toilet Bowl

How to Increase the Water Level in Your Toilet Bowl

‍If you’ve noticed that the water level in your toilet bowl is too low, it can lead to flushing problems and even clogging in the long run.

Conversely, if there’s too much water in the bowl, it may not flush properly and can result in overflow.

To avoid these issues, it’s important to know how to adjust the water level in your toilet bowl.

In this article, we will discuss three effective methods to get more water in your toilet bowl:

1. Ball-and-Arm Float Adjustment
2. Cylinder Float Adjustment
3. Installation of a New Fill Valve

Ball-and-Arm Float Adjustment

The ball-and-arm float adjustment method is one of the most common ways to increase the water level in your toilet bowl.

Here’s how you can do it:

1. Remove the Toilet Tank Lid: Begin by carefully lifting off the toilet tank’s lid and placing it on a stable surface. Take caution as toilet lids are made of ceramic and can break easily.
2. Check the Toilet Tank’s Water Level: The water in the toilet tank should ideally be resting 1 to 2 inches below the fill valve and the overflow tube. You can also refer to any lines or markings inside the tank that indicate the correct water level.
3. Turn Off the Water Supply to the Toilet: Locate the external water valve on the wall behind and below the toilet. Turn the knob clockwise to shut off the water supply. Flush the toilet to empty the tank completely.
4. Inspect the Float-and-Fill Valve: Examine the flushing mechanisms inside the toilet tank to ensure there are no obvious defects or damages. If you notice any issues, it’s best to call a professional plumber for repairs.
5. Check the Float Height of the Toilet Tank: The float, usually a plastic ball connected to a long arm on the fill valve, determines the water level in the tank. If the float is not at the correct height, it can lead to an imbalanced water level. Make sure the float is connected properly to the fill valve.
6. Adjust the Float Height: Using a screwdriver, locate the single screw at the top of the fill valve. Turn it clockwise or counterclockwise in one full rotation to raise or lower the float height. Avoid making large adjustments at once to prevent erratic flushing.
7. Test the Water Level: After turning the water supply back on, allow the toilet tank to fill for a minute or two. Flush the toilet and observe the water level in the bowl. It should ideally be about halfway full. If the water level is still uneven, repeat the adjustment process. If the issue persists, it’s advisable to seek professional help.

Cylinder Float Adjustment

If your toilet has a cylinder float instead of a ball-and-arm float, you can use the cylinder float adjustment method to increase the water level.

Here’s how:

1. Identify the Cylinder Float: Some newer toilets feature a modern 1-piece float, often referred to as a floating cup. This type of float is a solid cylinder attached to the fill valve’s shaft. Familiarize yourself with the type of float your toilet has.
2. Remove the Toilet Tank Lid: Lift the lid of the toilet tank carefully and place it on a stable surface. Take care to avoid any accidental breakage.
3. Turn Off the Water Supply: Locate the external water valve behind the toilet, below the bowl. Turn the knob clockwise to shut off the water supply. Flush the toilet to empty the tank completely.
4. Locate the Adjustment Stem: The adjustment stem is a slender tube attached to the fill valve, either running parallel or extending horizontally. It is used to increase or decrease the water level in the tank. Familiarize yourself with the flushing mechanisms in the tank.
5. Check for the Float’s Release Clip: Some cylinder floats may have a release clip that allows you to adjust the float’s height easily. Squeeze the release clip and raise or lower the float to the desired level. This will directly affect the water level in the tank.
6. Adjust the Float Height: Using two fingers, grasp the notched dial at the end of the stem. Rotate the stem clockwise to lower the float height or counterclockwise to raise it. Avoid making sudden adjustments to prevent inconsistent flushing.
7. Test the Toilet Level Height: After turning the water supply back on, flush the toilet multiple times to check if the water level in the bowl has increased or decreased. The bowl should ideally be about halfway full. Continue adjusting the float until the desired height is achieved. If the problem persists, it’s recommended to seek professional assistance.

Installation of a New Fill Valve

If the previous adjustment methods haven’t resolved the issue, you may need to consider installing a new fill valve.

Here’s how you can do it:

1. Replace Fill Valve If Adjustments Aren’t Helping: If your toilet continues to have flushing problems despite adjusting the float height, it may be necessary to replace the fill valve. This task involves opening the base hole of the toilet tank, so if you’re not comfortable with extensive repairs, it’s best to call a professional plumber.
2. Turn Off the Water Supply and Drain the Toilet Bowl: To install the new fill valve, you’ll need to drain the toilet tank completely. Locate the external water valve behind and below the toilet and turn the knob clockwise to shut off the water supply. Flush the toilet until the tank is empty. Use a towel or sponge to absorb any remaining water.
3. Detach Fill Valve from the Outside of the Toilet Tank: On the exterior of the toilet tank, you’ll find two nuts. Unscrew the nut connected to the water supply line and remove the supply line from the valve. Unscrew the plastic nut that secures the valve to the tank. Once both nuts are removed, the fill valve should come out easily. You may need pliers or a wrench to loosen the nuts.
4. Lift the Old Valve Out of the Toilet Tank: Carefully remove the old fill valve, including the attached float. Ensure to extract it without damaging or dislodging other mechanisms within the tank. Dispose of the old fill valve unless you plan to have it repaired.
5. Slide New Fill Valve into Place: Insert the bottom part of the new fill valve into the hole at the base of the toilet tank. Ensure it is securely installed, preventing any movement or wobbling.
6. Reattach the Water Supply Hose: Connect the water supply hose to the bottom of the fill valve and slide it onto any washers that secure the hose to the tank’s base. Tighten the large nut to prevent any leaks when the water supply is turned back on.
7. Turn Water Supply Back On and Test Flush the Toilet: Rotate the external water valve clockwise to restore the water supply. Test the toilet by flushing it multiple times to check the water level. Inspect the water shut-off valve and the new fill valve for any signs of moisture and tighten any loose connections if necessary. If the water level remains off, it’s advisable to seek professional assistance.

In conclusion, maintaining the correct water level in your toilet bowl is essential for proper flushing and to avoid potential clogs or overflow.

By following the methods discussed in this article, you can easily adjust the water level and ensure your toilet functions optimally.

If you encounter persistent issues or are uncomfortable with DIY repairs, don’t hesitate to contact a professional plumber for assistance.
