Many people use toilets every day without knowing how they work. At Lex’s Plumbing, we have worked with toilets for more than 10 years. If you are curious to know how toilets work, read this article—and if you need emergency plumbing or standard plumbing services near Frisco, contact Lex’s Plumbing.

Bowl Siphon
Did you know that if you were able to disconnect the toilet bowl from the tank, you would still have a functional toilet? Even without moving parts, the bowl is all you need for a working toilet. This is thanks to a curved pipe called the siphon tube, which is connected to the bowl. To understand how the siphon tube works, try pouring a cup of water into your toilet. You will notice that nothing happens—the toilet does not flush, and the water level stays the same. If you quickly pour a small bucket of water into the toilet bowl, however, it will be enough to fill the siphon tube. When this pipe is full, it sucks the water out of the bowl. Once all of the water is sucked out of the bowl, air enters the siphon tube, which produces that unmistakable gurgling sound.

Flush Mechanism
How Does Your Toilet Work? | Frisco, TXThe flush mechanism essentially serves as the bucket of water described in the last section. The tank takes 30 to 60 seconds to fill completely, at which point it holds multiple gallons of water. When you operate the toilet handle, a chain connected to the flush valve is pulled. Once this happens, the toilet tank drain hole is exposed, allowing the tank to dump its water into the bowl in roughly three seconds.

Refill Mechanism
The refill mechanism fills the tank back up once the toilet has been flushed. It does this by turning the water on or off based on the position of the filler float, a mechanism that rises and falls with the water level inside the tank.
