How To Adjust a Toilet’s Tank Float?

Every toilet tank has an inner water valve that maintains the inflow of water. Typically, when you flush your toilet, the inflow of water refill cycle begins. After flushing the toilet, the water is released from the tank. There is a float, sitting on the top position of the reservoir of water in the upper reservoir. So, when the water is released, it will drop down and involve the tank so that the water is released into the tank.

How To Adjust a Toilet’s Tank Float?

With these things, you have now understood the importance of a perfect toilet tank float. Because without functioning properly, a bathroom’s tank float can make serious problems. To be precise, if the tank’s float is not adjusted properly, it might not stop filling the tank with water. In addition to overfilling, the float might under-fill as well, causing the toilet to have an inadequate water supply.

This is why we have come up with this post, explaining the exact process of adjusting the toilet’s tank float.

How to Adjust the Tank Float?


Here is a two-step process for adjusting the tank float quickly –

Firstly, start by changing the height at which the float shuts off the water valve. If you increase the height of the float, there will be more water, filling the tank quickly. On the contrary, if you lower the height, the water level within the float will decrease.

Secondly, to adjust the float, you can eliminate the tank lid within the tank and then carefully set it onto a towel. Remember that using a tower in this process is mandatory because it will help you avoiding any damage to the lid or any surfaces of the bathroom.

What if the toilet is filling continuously?

This particular problem happens because of an overflow tube. Therefore, start examining the tube. If you see the water level has reached the top of the overflow tube, you have to lower the tank float. This move will automatically reduce the water level.

What if the toilet is not flushing the bowl completely?

In this case, you might have to increase the level of water in every flush. You can make this adjustment while increasing the tank float.

What if you want to conserve water?

If you want to save water, you should reduce the level of water used in each flush. To make this adjustment, you should pull down the tank float. Keep in mind you have to pull it down as far as you can. In this way, you could see the necessary change like – clearing the bowl entirely.

The toilet floats usually come in different sizes and shapes. For example – all older versions of toilets included floats hanging at the end of a framework with plastic or metal rod. This particular framework kept things together for the toilets float, and this is the place where you would find a screw as well. So, if you want to fix this type of float, you can do that by adjusting the screw to the level that shuts off the water valve.

In contrast to the older versions, the newer toilets possess a collar nearby the fill valve. Bear in mind this fill valve rides vertically in both upward and downward position. There is also a spring clip that connects a metal rod to the shut-off control mechanism of the valve. So, if you just squeeze the spring clip and make it go up and down the metal rod, you can adjust the toilet float quickly.

Bottom Line

The bottom line is many manufacturers make different toilet tank float, offering numerous variations to the fill valve mechanism. However, there is only one particular way with which you can fine-tune the water level. Above all, if you follow our above advice and instructions accurately, adjusting your toilet tank’s float would be a breeze!
