Sewage

Today, almost every home has a sewer system. Accordingly, a large number of people are faced with such a problem as clogged pipes. In such a situation, a person faces a choice: either call the master, or fix the problem on his own. You can also remove the blockage in the sewer pipe with your own hands, for this it is important to know the causes of blockages and the procedure for action.

Causes of blockages

Sewage clogged with plastic bags and rags.

The presence of such a sanitary device as a water seal, or siphon, is a common cause of blockages. This device is a U-shaped pipe. In this pipe is constantly water that prevents the penetration of stale air and the movement of water from the sewer. It is in this knee that debris accumulates, such as tissue fibers, hair, and other wastes that, when combined with food fats, form a cork. Such a process occurs unnoticed over time, but the result is a complete obstruction of running water, which, having filled the sink, cannot penetrate the sewage system.

Debris also occurs due to the ingress of foreign objects into the pipe that cannot physically pass into the sewer system. Such objects can get there and by chance, but more often than not, people let their confidence that the pipes will be able to absorb anything.

Problem areas in the sewers are horizontal pipes, or pipes with a slight slope. When installing pipes, it is necessary to comply with all rules and standards.

Tip! Clogging can be prevented by inserting special nets into the drain hole of the sinks.

Mechanical removal of blockages

The traditional device for cleaning pipes is a plunger. Pre-rubber bowl plunger can be smeared with petroleum jelly for better tightness. Lean plunger against the hole and press. Now you need to dial in the sink water to such a level as to cover the rubber part of the tool. Pipes in the bathroom often communicate, so you should tightly close the hole in the tub. Now we do up to twenty sharp movements with the plunger up and down, creating pressure drops in the sink, and abruptly tear it off. If the first time did not work, try again. As a rule, such actions give the desired result. Part of the garbage should go through the pipe, the rest - spill out.

More complex blockages, especially if they are formed deep in the pipe, are removed with a plumbing cable. A steel cable with a length of 3–5 m and a diameter of 1 cm must have a handle at one end for rotation, and at the other end a drill. To remove the blockage, you need to insert the cable into the drain hole and in a circular motion with a push push it forward. Such a flexible device should bypass all bends and reach the desired place. When the cable reaches the blockage site, it will immediately be felt. Then we make several progressive-return movements in order to pierce the resulting plug. Then pulls out the cable, clean it and repeat the procedure again. The purpose of this operation is to wind as much dirt on the cable as possible and push the rest through the sewer line. Now you need to rinse the pipes with hot water. Even if the pipes are plastic, you can still pour water into them, at a temperature of 70–80 ° C. Then we clean the cable again, dry it, roll it up and put it on the storage place.

If it is possible to dismantle the siphon, it can be cleaned using a brush and detergents. The siphon can be disassembled with a wrench, having previously protected the floor from leaks from the pipe with a rag spread out.

Tip! Due to the raids, the diameter of the pipe gradually decreases, which significantly slows down the passage of water. Therefore, timely cleaning of pipes - a pledge of durable plumbing service.

Chemicals

Elimination of blockages of sewage pipes can be carried out by chemical means. On the surface stages of a blockage, this is a convenient way to solve problems, as it frees one from mechanical actions accompanied by an unpleasant smell and dirt.

Consider a few chemicals that help cope with blockages.

Half a cup of soda and 3-4 tablespoons of coarse salt poured into the drain hole. Top half with a cup of hot vinegar. We plug the drain and wait 10 minutes.
Two bags of citric acid in 20 grams per 3 liters of water. It is necessary to pour this mixture into the sink and wait about an hour.
Chemicals purchased in the supermarket are likely to help in eliminating blockages. It all depends on the degree of clogging. Such funds have a long-lasting effect on garbage and even after flushing the pipes with water, they continue to have destructive effects. Pellets should be poured in a small amount into the hole and pour hot water. Gel-like agents are less dangerous for human hands and respiratory organs than powdered ones. Chemical methods, if not adhered to, can cause damage to rubber gaskets and plastic pipes. Means for bathroom equipment "Mole" has proven itself over many years of its existence. It can also be used from time to time as a preventive measure. Chemicals - an affordable and reliable way to dissolve deposits, sanitize the system and return plumbing working condition.
Many people know that Coca-Cola contains an acid called orthophosphoric acid. For the body, this acid in reasonable quantities does not pose a threat due to a stronger stomach acid. But with pipe blockages, according to eyewitnesses, this drink should cope. Half a liter of drink can be poured into the sink and wait an hour, then rinse with hot water. If you try this method, you will not lose anything, but the probability of a successful outcome does exist.

Tip! Work with chemicals in rubber gloves.
