To most people far from the wisdom of sanitary engineering, the phrase pipe does not mean anything( fun means "fun" in English, so the word is clearly not borrowed).To answer the question about what it is, only those who have had problems with it can. And repair it or replace it - the occupation is definitely not a pleasant one.
Piping pipe for WC
The pipe is often a continuation of the sewer. It is established for the withdrawal from the apartment of any "waste" water and waste of life. One of its ends is sealed with an elastic band for sealing with a toilet, and the second - is brought under the connector of the internal sewer.
There goes everything: water from the toilet, sinks, tub, washing machine and dishwasher. So the smell all this mixture has, to put it mildly, unpleasant, and it's better not to dismantle it yourself. However, in the presence of certain knowledge, this task is possible for all without exception.
It's easy to distinguish a fan tube from others - in order to have good bandwidth, it is always the most voluminous. Its length is arbitrary, and the shape can be indirect. Also it happens not only vertical, but also horizontal, sometimes - with corners.
In the Soviet past, brittle pipes, despite their weight, were installed to remove from the apartment. Now almost everywhere put, light, durable and reliable plastic.
During construction of the building, the riser pipe is installed vertically, branching the pipe by the penthouse. In a situation that could very well happen in reality, for example, someone on the ninth pulled back, sending about seven liters of dirty water down. The water had time to reach, say, to the fifth. As a result, it is possible to observe the effect of the popma pumping out the liquid from the pipes and hydraulic locks of the apartments of the eighth, seventh and sixth levels. In order to avoid such cases, the sewer riser is led out to the ceiling, leaving unclosed. If the system is correct, the "pump" simply pumps the air from the top, and the liquid from the toilet knees does not enter floors below. This system in the wisdom of plumbers and bears the name of the fan. When it is absent, the dwelling inevitably acquires a persistent smell of sewage.
By the way, a similar system is used in low-rise cottages. In order to install the fan tube, the private house must be above two floors and have several bathrooms. Also, the system is simply necessary for the amateurs to swim in their own pool or those who use some other devices capable of discharging large volumes of water into the sewer system. In addition, the pipe pipes are put in when there is a septic tank near the house( this word is called individual treatment facilities).
Also, according to experts, the pipe is needed for ventilation of the entire sewerage system. It helps to avoid the smell of feces, which appears because of the small diameter of modern siphons, if five to six days did not use any device, say, a shower.
During the installation of a fan pipe it is necessary to know and consider such simple features:
First of all, the size of the pipe, it is inadmissible to do less of the circumference of the riser, where it should be installed. Usually, it's about 110 centimeters. For obvious reasons, the edge of the pipe must be placed in the room where bad odors will not bother anyone( often a vent pipe or a shaft).
The laying of the fan knee should be carried out in a warm space, and it should end in the cold. Observe this condition is necessary to ensure good traction. Also, having built the fan communication outside the building, you will have to fight with a hideous sticky plaque of green color, the formation of which is already inevitable in the first year of use. Plaque will appear on the roof and those structures that are located above the end of the pipe. Of course, you should not "break" it in the attic."Cocktail" of unpleasant odors will inevitably seep into the rooms on the top floor.
Many owners of private houses have problems when the house has more than two sewer risers. A large number of pipes on the roof disfigure the appearance of the building. However, this problem is solved, you just need to use a special device.
In the attic, you can install only one fan tube, the rest "connect" to it through vacuum valves, which are made from a weak spring and rubber, necessary for airtightness. As could be guessed, the task of such a valve is to suck in an unpleasant odor as soon as the feces begin their journey through the sewage system.
In general, installing a fan pipe is a matter of how much compulsory, so simple. This process is small, than differs from the installation of sewage. Suffice it to show wit, and the bad smell of waste of human life will not bother any more, giving way to much more pleasant fragrances.
