Where is overflow tube in toilet tank?
flush valve
A toilet’s overflow tube is part of its flush valve. The tube rises from the siphon hole in the bottom of the tank to within an inch or two from the top of the tank and allows excess water to drain into the bowl.
Where is the overflow in a toilet tank?
The tank water level should be at least an inch below the overflow tube opening. The overflow tube is part of the flush valve — it’s the white plastic tube that you see in the middle of the tank when you remove the lid. When the float is adjusted properly, the toilet fill valve shuts off when the water level is an inch below the top of this tube.
Why does my toilet keep filling up with water?
Your toilet’s overflow tube ensures that the tank doesn’t overfill and flood your bathroom. But if the fill valve’s float is set too high, small amounts of water will leak into the overflow tube and into the bowl, resulting in the fill valve turning on automatically and topping up the tank periodically. Lower the float setting on the fill valve.
Why does the refill tube go into the overflow?
If that tube didn’t spray water in the overflow tube, the tank would have to fill all the way and then trickle water down the overflow and into the bowl. However, then there would be no way to stop this prosess, and the toilet would run continuously. The refill tube goes into the overflow tube and that water fills the bowl after each flush.

What should I do if my toilet tank is not filling?
For newer toilets, turn the fill valve adjustment knob with your hand to let more water into the tank. For all toilets, make sure the water level is about an inch below the top of the overflow tube. Flush the toilet and then check to see if the tank fills at the right rate and with the right amount of water.
Where does the water go after a toilet tank is filled?
As the tank refills, some of the water goes from your fill valve through the refill tube and in the overflow tube. The job of the overflow tube is to empty the water directly into your toilet bowl.
