Nowadays, there are a lot of way to call the greatness of inventions to human were invented by an English plumber called Thomas Crapper (c.1836–1910) that we can not live without it is “The Toilet”. We have so many names for something we care to talk about except the word “toilet” like loo, Wc, lavatory, water closet, etc. There must be a number that I have to show you, about nearly hafl of the world’s people (some 2.6 billion of us) are in an unhappy condition, they are lacking even basic sanitation. Otherwise, in Japan, they have a modern electronic toilets that do everything from opening and closing the lid automatically to playing music while you use them…
How does a toilet flush work?
Therefore, the toilet is a sanitary facility that is become too familiar to everyone. However, in the process of using it, we just can not prevent some failure or break-down situations that is affect directly to the life quality of your family. In those moments, the basic understanding of the toilet and its principles of operation will help you to overcome the limitations of the damage. So let’s take a closer look how does a toilet flush really work?
At first sight,dual toilets system seem quite simple: it have a waste pipe running through the floor and a water tank up above (named a cistern) waiting to flush into it when you pushes a button or pulls a lever or a chain. Most flush toilets are totally mechanical: pull the chain and the cistern empties through the force of gravity, washing the bowl clean to use again. They are literally mechanical because they flush and refill using levers inside and levers are examples of what scientists call “simple machines”.
A toilet works because of gravity. When a flush lever is pulled, a plug will open, allowing water to flow out to fill the water tank. When the tank is full enough, gravity causes the liquid to flow out through a bend in the pipe, called an S trap.
There’s a little bit more complicate than this which help to develop and accelerate the flushing procedure.
What happens when you flush?
Press the handle to flush the toilet and you operate a lever inside the cistern.
The lever opens a valve called the flapper that allows the cistern to empty into the toilet bowl beneath through a mechanism called a siphon.
Water runs from the cistern and go through holes in the rim so it washes the bowl as well as flushing the waste away.
There is enough water flowing down from the cistern to flush the toilet around the S-bend (S-trap). This produces a siphon effect that sucks the bowl clean. It also ensures some water remains at the bottom of the bowl, which improves hygiene.
The contents of the toilet are flushed down the main drain.
As the cistern empties, the plastic float ball (ussually red) falls downward, tilting a lever.
The tilting lever opens the ball valve at the base of the cistern (or on one side of it), which works a bit like a faucet that controls the water flow to the tank. When the water reaches a certain level in the tank, the ball floats level on the water, shutting of the refilling mechanism. When the tank is empty, the float ball falls freely allowing the valve to open, filling the tank.
The “Toilet” changed the world.
In conclusion, for centuries now we have enjoyed the convenience of the modern toilet, it has made homes, towns and cities to be a cleaner places to live in. Otherwise, in our daily life, where water is considered as a limited resource, the huge amounts of water that are used daily world wide in our “flush systems” are being questioned. The toilet has also created a whole new profession job called plumbers and its associated industry. More environmentally friendly “toilets” are being invented to run with less or no water…
