How to fix a hole in a plastic sewer pipe. Crack in the sewer pipe: ways to fix the leak. The best way to repair a sewer pipe.

Reliable operation of the sewer system is the key to a comfortable stay in any room, regardless of whether it is an office or a residential building. That is why it is so important to monitor the health of the collector and eliminate possible risk situations in time. But what to do if the repair of sewer pipes was suddenly required, and it is impossible to call the master for any reason, or simply there is a desire to deal with the problem on your own? In the material below, we will analyze in detail how to repair sewer pipes with our own hands and at the same time do everything correctly.

Important: self repair collector can only be carried out if the system is plastic. Cast iron repair sewer pipe only professionals can do it, since this part of communication is very important and requires certain skills.

Common sewer failures

Important: very often sewer and water pipes are hidden behind decorative panels and shields. That is why, in the event of leaks or blockages in any of the communications, it will be necessary to dismantle parts of the wall cladding in order to identify the exact location of the malfunction.

Heater without errors: Part 1, Installation planning

Most often it is an electric boiler or gas stove. If they are older and therefore have low performance or have problems with their operation, we are faced with the need to replace. We have different variants choice. For these reasons, designers recommend that the water be dried sufficiently. outer pipe. Its color can then be adjusted to match the façade or partially hide the pipe with a special sheath.

Important elements that make up an internal wastewater treatment system

Adequate ventilation is essential for the proper functioning of the sewer system. This can be achieved by installing an exhaust pipe and air valves. In addition, there should always be water in the siphons of sanitary appliances; thanks to the cork made in this way.

Most frequent breakdowns that happen to the sewer or plumbing are:

• Blockages and blockages in the sewerage system. In this case, stagnation of water with faeces in the toilet or a wastewater outlet in one of the other plumbing fixtures will be clear evidence.
• A leak in certain sections of the sewer or water pipe.
• Cracks in plastic pipes.

Important: in any of the cases, repairs must be started immediately, otherwise it threatens a global catastrophe for both residents of a private house / apartment and neighbors (in a high-rise building).

We are buying an old house: how to assess the condition of the building?

Let's ask the seller if the house is not flooded. Rusty metal parts may indicate high humidity in the basement. The next step is to evaluate the remaining rooms of the old house.

Sewerage at the design stage of a detached house

Therefore, the installation of the sewer must be entrusted to an experienced installer. Then we will be sure that the diameter of the pipe, their length, the way they move and the drops will be correctly adjusted. Thanks to this, we will avoid clogging the installation, expansion.

Blockages in the sewer

This type of failure is the most common, especially if the manifold is old or misused. That is, traffic jams and congestion in this case are formed not so much in the central pipe, but in the siphons under the bathroom or sink. Typically, the congestion is formed by hair and other fibrous debris. Connecting with sebum and dirt, they cling to the siphon lintels and interfere with the outflow of water. If this is observed in your sewer system, then you can use a simple plunger to clean the system.

• Water is drawn into the sink or bath. The device is installed in such a way that its rubber cap fits snugly against the drain hole, and sharp and tight movements begin in the up and down direction. The vacuum that the plunger creates must either pull the debris out or push it further down the system.

Important: if there is an overflow in the sink and bath, then they must be closed for the duration of the plunger treatment. Otherwise, a vacuum cannot be created.

Basement in a new role: how to grow a house?

The level of complexity of the pledge depends on the level ground water. It is worth lowering it around the foundations of the drainage belt, a system of perforated pipes laid along foundation foundations surrounded by gravel pebbles and connected to inspection and collection wells.

Water from the water supply and from wells in the same house

In the event of a water supply failure or when the pressure drops, do not put water in a tank with its own well. It is also useful to use it to irrigate the garden, wash the car or clean the area around the house - because it is almost free.

Good and bad radiator connections

The correct distance is 12 cm from the floor and 10 cm from the bottom of the window sill. On the contrary, when installing radiators, you need to leave only 5 cm from the bottom and top. Heater connected to the unit Each radiator is connected to the system central heating with two pipes: the power supply that it controls.

• If the plunger has not coped with the plug, then you can use a chemical aggressive agent that will simply corrode the plug formed in the system. It is necessary to use drugs very carefully, exactly following the instructions. As a rule, a dry product is poured into the drain of a sink or bathtub and poured with a glass of water. The edible mixture is left for 30-40 minutes, after which it is washed out very hot water. The congestion must go.
• As a tool to remove the plug, you can use a flexible cable with a rough tip. It is launched into the sewer pipe and advanced up to the congestion. With rotational movements, the cork is crushed or taken out. Sewer pipes are flushed with plenty of water.

Important: for cleaning plastic pipes, the tip on the cable must be rubber or de-plastic. Otherwise, there is a risk of scratching the pipe from the inside and after that debris will accumulate in it.

Install your heat pump without complications

Pipes for extracting heat from the ground. Much easier and quieter. The solution to this problem has been provided by the evolving technology of heat pumps, which extract heat from the outside air. They do not require boreholes, which greatly simplifies installation. But even with heat pumps.

Gas boiler - which room

A few years ago gas boilers were installed mainly in the basement, in a separate boiler room. However, it is prone to errors and the wrong version of the roof. Previously, thermal insulation was installed on the ceiling above the last floor, on which the layer of pressure and moisture, which was not covered, collapsed so quickly. Fortunately, at present, moisture-proof insulation is made of.

Sewer leaks

As a rule, most often a leak is formed at the joints of cuffs and corrugated sections of the pipeline. This indicates an inaccurate and leaky fit of one element of the system to another. In this case, you just need to replace the rubber gasket and tighten the connection with high quality. To be sure, the joints must be covered with sealant.

• A leak on a section of a plastic pipe can be eliminated by replacing a section of the main line and its high-quality docking with the main collector using couplings and seals. After that, the pipe does not leak.
• If a leak is found on a piece of cast-iron pipe with cement putty, then the work here will be a little more difficult. First of all, completely knock down the entire layer of cement. Residual pieces of stuffing are removed from the cracks and the place is thoroughly cleaned of debris. Now you need to lay a new layer of packing from a mixture of cement, asbestos and water. The solution is prepared in a ratio of 7:3 plus the amount of liquid that will make it possible to obtain a suspension of the consistency of soft plasticine. The top of the joint of the cast-iron pipe can be covered cement mortar, which is kneaded in proportions of 1:10 (cement:water).
• Lead pipes (if they leak) are treated according to the principle of cast iron pipes. Only here all the old lead is removed from the joint and new pieces of material are laid. It is very convenient to use just a chisel.

Important: lead or asbestos packing for cast iron pipes can be replaced with a liquid glass gasket. It is made from standard bandages and a mixture of cement and liquid glass. The technology of work looks like this:

Well - water from own well

Well water must be treated, or at least filtered, so as not only to add grains of sand to the glass, but also invisible pollution. Cooking, unfortunately, is not always enough, because only bacteria and viruses that are lost in the process are removed.

Gas condensing boiler - when is it worth it?

Simply attach the special set of horizontal exhaust and extract air pipes to the outer wall or hang on it. For such a set, we will pay several hundred zlotys, and a brick chimney with the cost of construction is at least several thousand zlotys.

• The cleaned joint of the sewer cast-iron pipe is wrapped with a bandage soaked in the prepared mixture. Given that liquid glass dries very quickly, you need to work without delay. After a couple of months, such a winding can be successfully painted in any color.

Crack in sewer pipes

A crack is the most dangerous of the problems in the sewer system. Such a small, at first glance, trouble can bring very big problems in the form of a gradual increase in clearance and an unexpected gust of a sewer. Is it worth talking about what will follow next? Therefore, it is better to replace the pipe section immediately after a crack is detected. Especially if it's plastic. To replace cast iron pipes, you will have to invite professionals.

If there is no time or opportunity to replace the pipe section at the moment, then you can cover up the crack for a short time. But for the shortest time.

• For a plastic pipe, a sealant is used to treat the gap. From above the crack is closed with adhesive tape.
• The cast-iron pipe will have to be “treated” more seriously. To do this, you need to expand the gap and degrease it. The resulting lumen is coated with a mixture phosphoric acid and copper in a ratio of 2:3.

We repair the sewerage of a private house

In this case, do-it-yourself repair of sewer pipes will be more time-consuming, since a larger section of the collector is located in the ground. And here, in case of leaks, it will be necessary to replace the worn-out collector of the outer part either with the performance of bulk earthworks, or using one of two technologies:

• Burstlining. In this case old pipe sewers are dug out of the ground and simply cut along on the spot. Sections of the disassembled collector are pressed into the walls of the soil, and a new pipeline is mounted on the vacated space.
• Relining. This way is even simpler. In this case, they pull inside the existing worn pipe right in the ground corrugated pipe smaller diameter.

Thus, it is possible to quickly and reliably eliminate the depressurization of the outer part of the collector directly in the ground.

Preventive measures against sewer breakdowns

To avoid a forced and costly repair of the water supply or sewerage system in the event of a leak, it is better to take preventive actions in relation to the system in time. Namely, comply following rules sewer operation:

• Do not flush loose building materials such as cement, asbestos, sand, small pieces of stone, etc. into the system.
• Avoid getting rags and personal hygiene items into the sewer.
• Install under kitchen sink And dishwasher grease traps.
• Periodically clean the pipeline using hydrodynamics (water supply under great pressure), thermal (hot water) or chemical (aggressive preparations) treatment. This is done by specialists.
• If there is a crack, to prevent leakage, the pipe section must be replaced as soon as possible.
• The old sewer system made of cast iron in apartment building it is advisable to change to plastic, since plastic has a lot of advantages, such as durability, inertness to aggressive environments, ease of maintenance and installation, environmental friendliness and strength.

And remember, it's always better to prevent a leak than to fix it.

No one is safe from the little ones domestic problems and unpleasant surprises that plumbing periodically presents.

In this article, we will try to figure out how and how to fix a leak in a sewer pipe.

Causes

First, let's figure out why the sewer pipe is flowing.

• Most often, a joint runs between cast-iron pipes. As a seal, oiled bondage has traditionally been used - an organic fiber that has a rather short service life.

Useful: where special reliability is needed, cast-iron sewage is minted with a graphite gland. Asbestos fiber with graphite, unlike bondage, is not biodegradable and lasts for decades.

elimination

Let's analyze several typical situations and find the simplest possible solution for each of them.

blockages

If it formed within your apartment, up to the riser, it’s not a big deal. It is enough to turn off the water and, armed with a plumbing cable, clean the blockage (as a rule, it is caused by the accumulation of frozen fat). Then the sewer is spilled with more hot water: the cable will only pierce the fat plug, while the water will soften it and take it on a long underground journey.

Everything is much worse if you live on the first floor, and the blockage is in the basement. All drains from the upper floors will flow to you; at the same time, any plugs for sewer pipes will be useless: water will go through the toilet, bathtub, washbasin and sink.

The only sensible measure before the arrival of the emergency service is to go down to the basement with a pair of adjustable wrenches and remove the cover from the revision of the riser. This won't solve the problem, but it will move the epicenter of the drama out of your apartment and into the space below.

Tip: if you kindly leave the revision cover and bolts in a conspicuous place, many words will not be said to you that are not recommended for pronunciation in a decent society.
The emergency service has a lot of work, and in addition to quests to find spare parts for the sewer.

joints

How to fix a leak in a sewer pipe at a joint?

1. Any displacement of the compensating pipes is quite predictably corrected by restoring their original position.
2. If the riser, fixed by the neck in the ceiling, sank, and the joint itself is inaccessible and flows right inside the ceiling, the riser will have to be raised and fixed in its original position.
   To raise the pipe by 5-10 centimeters, you will have to build a system from a lever (crowbar or pipe), supports under the lever and a wire clamp. fixed in the desired position with standard purchased fasteners; for cast iron, the simplest solution is a thick wire clamp, with which the pipe is tied to a crutch or anchor in the wall.
   Problems with aesthetics will be solved by the construction of a light drywall box or plastic panels.

1. If a plastic sewer pipe is leaking at the connection, you will have to disassemble it and reconnect it after replacing the seal. Rubber rings for sections 50 and 110 mm are easy to find on sale. A temporary solution is to put the joint on a sealant.
   Disassembly will be required in any case: an attempt to cover up the joint from the outside is doomed to failure.

A magical artifact to eliminate leaks of this kind. The cost in Russian retail is from 5 to 10 rubles.

1. How to cover up a cast-iron sewer pipe flowing at a embossed joint? Again silicone sealant. First you need to carefully clean the remnants of the old putty from the socket and, if possible, remove small debris from there, then dry the pipe.
2. How to cover up a sewer pipe if the connection, due to its vertical position, does not flow, but is a source bad smell? In this case, ordinary cement will do. The addition of a small amount of liquid glass (sodium silicate) will speed up the setting and make the connection stronger.

Cracks and holes

How to seal a sewer pipe if a crack or hole appears on its straight section?

1. Plastic is easily repaired by applying a sticker over the defect of a fragment cut from a pipe of the same diameter. Any universal adhesive suitable for gluing polypropylene or PVC can be used. A self-prepared solution of plastic in acetone is also suitable.
2. small through hole V cast iron pipe eliminated with an aluminum clamp and a piece of dense rubber. The service life of such an impromptu repair kit is practically unlimited.
   
3. Serious damage is treated by replacing the pipe section. A temporary solution is a rubber bandage. A pharmaceutical rubber bandage or a bicycle tube cut along the length is wrapped around the defect area as tightly as possible and fixed with an aluminum clamp for a screwdriver or tying wire.

Conclusion

As you can see most of Problems may well be fixed by you yourself. As always, in the presented video in this article you will find additional information on this topic. Good luck!
