plumber services London About plumber's snake
A plumber's snake is a slender, flexible auger used to dislodge clogs in plumbing. The plumber's snake is often reserved for difficult clogs that cannot be loosened with a plunger. It is also sometimes called a toilet jack or electric eel.
Plumber's snakes have a coiled (helix-shaped) metal wire with a broader gap between the coils at the terminal end. The operator turns a crank to rotate the helix as it moves through the pipe.
If the clog is caused by a dense, but shreddable obstacle, such as tree roots or glass wool, the auger might break it up enough to enable flow. A small, lightweight obstruction might be snagged or corkscrewed by the auger, enabling the operator to pull it away. As the auger rotates, it also flails against the interior walls of the pipe, scraping off minerals and oil.

Why bother with expert? - plumbing
When it comes to repairing things around the house, men often feel compelled to do it themselves, rather than spent money on overpriced expert. More often than not, it is worth the effort, but what happens when you mess with crucial installations, that you know very little about?
Broken chair or squeaky hinges are one thing, but if you mess up with your drainage or plumbing, all hell can break loose. From time to time, it is really wise to call in the plumber - you may pay more than you would want to, but not necessary more than it is worth. Especially if you would do this yourself and mess up.
Besides, do you really have all the necessary things for all the repairs? I doubt that, let alone the tools, which you may or may not have. If you buy unnecessary spare part, what will you do with it? Plumber can always use it, but he probably wouldn't make the mistake in the first place.
To sum up, it is good to do things around your house by yourself, but don't be afraid to call in the specialist from time to time.
Plumbing - the not so modern history
Plumbing was very rare until modern cities grew in the 19th century. At about the same time, public health leaders began wanting better systems to get rid of waste. Before this, people got rid of waste by collecting it and dumping it onto the ground or into rivers. However, there were some plumbing pipes in the city settlements of the Indus Valley Civilization by 2700 B.C. Plumbing was also used during the ancient civilizations such as the Greek, Roman, Persian, Indian, and Chinese civilizations as they built public baths and needed drinking water, and somewhere to drain waste. The Romans used pipe inscriptions to stop people from stealing water.
These systems did not improve much over the years. There were almost no improvements from the time of the Roman aqueducts and lead pipes until the 19th century. Eventually the development of separate, underground water and sewage systems got rid of open sewage ditches and cesspools. Most large cities today send solid wastes through pipes to sewage treatment plants. Treatment separates water from waste and makes the water more pure before it goes into streams or other bodies of water. Most places stopped using lead for drinking water after World War II because of the dangers of lead poisoning. At this time, copper piping was started because it was safer than using lead pipes.
