As the water level in the tank rises, the float ball or float cup rises along with the water. The fill valve shuts off when the water reaches the required level, and the toilet stops "running.

The toilet has made homes, towns and cities cleaner places to live in. Because water cleans the toilets very well, highly contagious diseases cannot spread as easily as in the past, where very often thousands of people died at the same time, and to keep epidemics under control, cities and villages weren't allowed to grow beyond a certain population.
Toilets help public health of today to keep higher standards than in the past. That allows us today to live in much bigger cities than in the past, not being afraid of getting sick. Big cities were a requirement to start the industrial revolution in the s. We see that although toilets might not look like such an important invention, they have had a huge impact on our modern world. The toilet has also created a whole new profession called plumbers and its associated industry.
To have a flush toilet in your house, first of all one has to have fresh and clean water supply. A better organization of the cities was needed for that. The lever and the siphon also had to be invented before the flush toilet could have come into being. Wikipedia has related information at Flush toilet. From Wikibooks, open books for an open world.

The rubber flapper is designed to release water when the toilet is flushed and then close the water intake hole afterward so that the proper amount of water remains in the tank. Solution: Flappers are inexpensive items and can be found at any hardware or home improvement store. Turn off the water and drain the tank before swapping the old flapper out for the new one, then try flushing to the toilet again to ensure the problem is resolved.
Problem: Sometimes the lift chain, which attaches the flapper to the flushing handle on the outside of the toilet, can have too much slack and make the handle unable to raise the flapper and thus flush the toilet. Solution: To solve this problem, you need only adjust the length of the chain to shorten it so that the chain can provide pull sufficient to raise the flapper off of the flush tube and allow water to flow when the handle is pulled.
These four situations are by far the most common reasons for a toilet failing to flush properly, so we hope this post will help you take care of flushing problems quickly and easily next time they occur. If you like a tidy toilet bowl that's half full of sparkling clear water, the dual flush concept will be a bit of an adjustment. Typically, dual flush toilets only retain a little water in the bowl, and flushing won't always get rid of all the waste.
Even in full flush mode, there's some occasional streaking. With a dual flush toilet, you'll probably use your toilet brush more often, but then you probably won't need to keep the plunger nearby. If you have qualms about a toilet system that may leave a little bit of waste behind in the bowl, consider the shelf toilet. Available in some parts of Europe, particularly Germany, the shelf toilet allows the user to give his poop a visual inspection before sending it on its way.
Solid waste sits on a molded enamel shelf where it can be viewed easily and then dispatched. As unappealing as this may seem to the uninitiated, periodically inspecting what's leaving your body may be a good way to spot a problem symptom, like a bloody stool, before it becomes a life-threatening condition. Although this particular toilet design may have limited appeal, it illustrates that there's more than one way to design a toilet [source: The International Center for Bathroom Etiquette ].
The process of installing a dual flush toilet is similar to that of installing a low flow toilet. Although using a professional plumber is the easiest way to go, it's a job that a do-it-yourselfer can tackle in an afternoon. If you're planning on doing the installation yourself, there are a few things to consider.
The general suggestions below will give you an idea of what's involved, but dual flush toilet models differ, so pay close attention to the instructions that come with the dual flush toilet model you're considering:. If the prospect of installing an entirely new toilet doesn't appeal to you, there are retrofit kits available that will convert your existing toilet to a dual flush system. The bowl will still use a siphon system to evacuate waste, but you'll be able to conserve water by selecting which flush mode you want, partial flush or full flush.
Interested in the future of the U. In the next section, we'll take a look where we're headed and what that might mean for dual flush technology. If you're wondering if people with dual flush toilets flush more often to do the job.
A study conducted by the Canada Mortgage Housing Corporation using flush counters recorded a slight increase in flush rates during their test, but the small increase may have been due to curiosity about how the toilets worked [source: Canada Mortgage ]. In , the National Energy Policy Act was signed into law. It requires that toilets sold in the United States use no more than 1. This mandate to conserve has given rise to a new generation of high efficiency toilets HETs that use technologies like pressure-assist, gravity flush and dual flush to whisk away waste using as little water as possible.
Of the new technologies, the dual flush method has the advantage of intuitive flushing, where the operator can decide electively that less water is needed and use one gallon 3 liters or less per flush instead of the 1. Although toilets purchased for new construction and retrofits must meet the new standards, millions of older water-guzzling toilets are still out there.
As water and sewer costs keep rising, low flow toilets are becoming more attractive to the American consumer, and local and state governments are using rebates and tax incentives to encourage households to convert to these new technologies. The advantages of low flow toilets in conserving water and reducing the demand on local water treatment facilities is pretty obvious. According to USA Today, the average person flushes the toilet five to eight times a day, and at a greedy five gallons a flush, the numbers start to add up quickly [source: Winter ].
According to the Environmental Protection Agency , completely eliminating old style, water guzzling toilets would save about 2 billion gallons of water each day in the United States [source: Green Living ]. With a growing population, an aging water treatment infrastructure and the looming threat of global warming contributing to uncertain weather , water conservation will continue to be a big issue.
How does the dual flush toilet fit into this picture? No one knows for sure. Most major toilet manufacturers are gearing up to provide these water saving toilets, but whether or not the American public will embrace a change in the way they approach their bathroom habits remains to be seen.
Ever wondered how much water you use to brush your teeth or take a shower?
