Step 1: Check the Water Level in Your Toilet Tank

To begin, unscrew the lid of your tank and inspect if the water level is beneath or equal to the overflow tube.

If it is, then you should turn off your main water supply valve and wait for the tank to drain completely before beginning repairs.

Step 2: Adjust the Float Arm and Float Ball Assembly

Once you have drained the tank, locate the float arm assembly on the side of your tank.

This consists of a float arm connected to a float ball that can move up and down along with the water level in your tank.

You will need to adjust both components together so that they are set at just below the overflow tube level when fully submerged in water.

This will help ensure that your toilet will fill properly when flushed again.

Step 3: Check for Leaks or Obstructions in Your Toilet Tank

After adjusting your float arm and ball assembly, fill up your toilet until it reaches its appropriate level and flush it once more.

You should now see that it is refilling correctly without any issues.

However, if you notice any signs of leakage or obstruction while flushing, these may need to be addressed as well before using your toilet again safely.

Step 4: Replace Any Damaged Parts If Necessary

Lastly, if any parts appear damaged or worn out during this process (such as valves or seals), they should be replaced before using your toilet again since they may cause further problems down the line if not fixed properly.

Whenever replacing parts, make sure that you use parts specifically designed for toilets as these may provide better performance than generic ones available from hardware stores.


With these simple steps, fixing a toilet tank not filling after flushing should be quick and easy!

Just remember to check for leaks or obstructions in addition to adjusting its float arm/ball assembly when necessary—and never forget to turn off your main water supply valve before making any repairs!

The sooner you can address these issues with proper care and attention, the sooner you can get back to enjoying a functioning toilet again!
