The only major difference between your modern toilet tank and any other traditional toilet tank’s flushing system is that yours has a toilet Fill Valve instead of a ball float which functions the same way technically. But the advantage of a fill valve is that it’s smaller in size than a ball float, so it fits in any new compact cistern easily.

Understanding the fill valve

The fill valve is usually fixed onto the left portion of your cistern. This is the valve that fills in the required amount of water into the toilet tank more efficiently than a ball valve, making it more economical in the long run and stop the toilet keeps refilling. They come with many different types of floats that does the job of the ball float even better.

As a plumber, I do suggest you to replace your Fill Valve every five to six years in order to minimize unwanted disruptions and also to ensure a smooth flushing experience throughout.

Let’s remove the existing valve


Just head on over to any local hardware store where you can buy a new fill valve assembly unit or Better buy it here amazon. A good one should include a refill tube, gaskets and a lock nut along with the Fill valve assembly.

You’ll be needing an adjustable wrench and a small bin or a container to collect water in order to do the replacement of the Fill Valve. But, before we begin, shut off the water supply valve first and then open up the lid of the toilet tank and give it a proper flush. Now we are officially ready for the replacement.


Take a look at your old Fill Valve. If you feel that it does not have much wear and tear with the base in usable condition, then that’s a good thing as the replacement process will be much easier for you. Simply pull up the lock ring by reaching to the base of the fill valve so that you can remove the refill tube by pulling the Fill Valve upwards from the base easily.


Now it’s time to take out the new Fill Valve for installation. Just like the old one, the new fill valve also comes with a base of its own. But, you won’t be needing it since we already have the base of our existing fill valve we had earlier. Therefore, you can install the new Fill Valve by simply pushing it down to the existing base of your tank.

Now, lock the ring located behind the fill valve down into place and connect the refill tube to the overflow tube. At this stage we must keep in mind to properly adjust the water level accordingly, so that it’s not set too high. This will prevent the toilet toilet without float ball and tank from keep filling.


And that’s how to fix a toilet and also how to adjust toilet float that keeps running without a ball float in case if the base of your old fill valve is in a good and usable condition. That’s great, but what if the base of your Fill Valve isn’t in any suitable condition for further use.

Well, in that case the whole unit will have to be removed and replaced accordingly. But this isn’t any harder than the previous task. So, let’s take a quick look on how to do a complete replacement as well. This is where we are going to use the tools mentioned above earlier.


Make sure that your toilet tank is empty and if toilet running no float ball, place the small bin or container under the water supply hose to let the water trickle down into the bin/ container we positioned, as there will be more than just a few drops of water flowing down.

Now stick your hand to the base of the tank to unscrew the hose and you will also have to use an adjustable wrench to remove the lock nut properly.

That’s it, now you can remove the entire assembly and you can throw this old unit into the garbage straight away. Now you can install the new unit with ease by adjusting its height in order to match the height of both the tank and the overflow tube accordingly.
