Living in a country house must be accompanied by certain comfortable conditions, no worse than in a city apartment, and sometimes even better. quality system sewerage plays an important role in this.
You can build it yourself, however, before digging a pit and buying necessary materials, you should find out if there is a central sewerage system near the house. If the house is located on the territory of the city, then such a system probably already exists. It is often built in recent times in small new towns.
If the central system exists near a private house, then a tie-in to the sewer will be necessary. This stage of work can be done with the help of professionals from specialized enterprises who will do everything quickly, efficiently and help you arrange Required documents and permissions.
You can make a tie-in yourself, however, you will have to run around to draw up various certificates and approvals. But it will save a lot of money that can be spent on other needs. country house.
At self-connection to the sewerage system, you should never do this without the necessary permits.
Illegal tapping into the sewer will lead to the fact that a large number of funds will be spent on paying a fine and dismantling materials.

There is another way to save money. It is necessary to offer the company that maintains this sewerage system, the participation of money in the modernization of the existing branch for the removal of wastewater. This is beneficial to both parties. In this case, the official organization will take on part of the work of drawing up a plan, calling a surveyor and registering a modernized branch.
Before cutting, it is necessary to carry out preparatory work which can be divided into three stages:
- construction of a revision well on the site of the house;
- laying a trench through pipes and connecting to a well;
- connecting the internal sewerage system to these devices.
An insert into the central sewer implies the obligatory presence of an inspection well, which is necessary for the maintenance and repair of an individual pipeline.
After completing this work, please contact specialized enterprise to connect. At this stage, you can also save some money. You need to contact your neighbors and find out from them if they want to connect to the central sewerage network. With their consent, the connection will be much cheaper.
In order to connect to the city sewer, you must do the following:
- call an employee of the land committee to create a plan of the site and draw on it the house and the route of laying the sewer system;
- submit an application for the development of technical conditions for sewerage equipment;
- conclude an agreement with a design organization on the drafting of a tie-in into the city sewerage system, then approve the project at the water utility company and with the architect;
- obtain the permission of the architect for the enterprise that will carry out the work on the tie-in;
- obtain the written consent of the neighbors to carry out work near their homes and connect to the sewerage system;
- if for tie-in it is necessary to dig pavement, obtain permission from the enterprise operating the road;
- notify the water utility in writing before starting work;
- the final stage of paperwork - the water utility accepts the project and concludes a contract for wastewater reception services.
As a result, it became clear how to connect to central sewerage.
In this case, it is necessary to make a slope of about two millimeters per running meter pipes for the normal output of sewage and waste.
Pressure sewer connection
If Vacation home located on the ground lower than the central sewerage pipeline, it is necessary to equip a pressure sewer on the site before the tie-in.
Pressure sewerage scheme for a private house: 1 - building; 2 - receiving well; 2a - sump; 2b - pumping capacity; 3 - manhole, transition of the pressure line to gravity; 4 - connection well ( local network); 5 - release from home; 6 - pressure line; 7 - gravity line; 8 - street highway; 9 - lattice; 10 - pump
To perform this work, it is necessary to determine the location of the receiving well on the site and coordinate its equipment with neighbors.
Sewage and waste must be collected in a separate well, and then, using a pump, they must be transported to common system sewerage. The power of the pump depends on the amount of effluent rise and the length of the pipeline section.
A good option may be to connect several neighboring houses at once. In this case, the receiving well to go to centralized sewerage can be done jointly with the mutual benefit of all project participants.
Storm sewer connection
After deciding how to connect to the central sewer, you should consider the issue of withdrawing rain and melt water from the site of the house.
If it is possible to drain directly on the ground near the country house using drainage system, then this work can be done with minimal cost. If this is not possible, then rainwater must also be discharged into the central sewerage system.
Such a procedure is simple, however, it should be taken into account that during heavy rainfall, the water flow can be so large that the receiving well will not cope with the task and sewage will come out. The consequences will not be very pleasant for the owner of the house and his neighbors.
Therefore, you will have to make a tie-in for storm sewers separately, since throughput the central pipeline is much higher than the private one.
As you can see, the costs are significant. Therefore, to save money, you can make a separate tank on the site of the house and collect rain and melt water in it. Then it can be used for watering the garden, vegetable garden and other household needs. Experts advise to make a natural filter in front of the rainwater tank, which is a small sump.
When building a private house, questions arise related to water supply and sanitation. If the house is in close proximity to locality, then, most likely, there is a central sewer near the house. In this case, the most convenient way drainage will be connected to a centralized sewer network.
Connection methods
Depending on the type of central sewerage passing near a private house, experts distinguish between:
- Separate connection to the central sewer. This method is used if it is required to separately connect domestic sewage and storm sewer private house.
- A mixed connection is used when the nearby sewer is a mixed type system. In this case, there is no need to insert two separate pipes.
If a a private house is connected to a separate sewer system, then you can either additionally conduct a private one into a common system, or use rainwater for domestic needs. For this on personal plot a tank is installed to collect sediments, into which the pump is immersed. Use rain water can be used for watering plants, washing cars, garden paths or building facade.
If the water obtained after precipitation is passed through filtration systems, then it can additionally be used for washing clothes, washing dishes and other household needs.
Connection process
Main stages of work
With any method of water disposal, you can contact a company whose specialists will carry out all necessary work, or do the connection yourself. If the owner of the house prefers to do all the work himself, then he must adhere to the following plan:
- At the first stage, you will have to contact a surveying company to develop a scheme possible connection. It should be noted that the services of such organizations are paid. You can reduce costs if you connect the house to the central sewer not alone, but together with your neighbors.
- Apply with a package of documents to the company that services the selected sewer system. Employees of the company will develop the necessary for connection specifications.
- Coordinate the connection scheme and specifications with the architects.
- In addition, coordinate the project with other organizations whose networks are located on the proposed pipeline route. This includes traffic police (crossing the road), heating and electrical networks.
- Carry out preparatory work to the point of insertion into the central system.
- In the presence of a specialist, connect a private house to the sewer system.
- Notify the organization servicing the sewerage about the tie-in and conclude a contract for water disposal.
Registration of necessary documents
From the main stages of the connection, it can be understood that the tie-in to the central sewer is accompanied by a lot of approvals and documents. The homeowner will have to collect a package of documents, which contains:
- plan land plot and household sewerage;
- documents certifying the right to own a house and a land plot;
- the scheme of the proposed connection, developed by the employees of the water utility and signed by architectural organizations;
- permission of the architect to carry out work on the tie-in personally or by a specific organization;
- other permits in case of pipes passing through central networks and highways;
- consent of neighbors (document may be required additionally);
- application to the service organization, notifying the time of the work.
Tapping into the central sewer without prior approval will entail a large fine and the cost of dismantling a private sewer.
Preparatory work
The preparatory work that must be carried out after the collection of documents, but until the moment of direct connection to the network, consists in:
- digging trenches for laying pipes;
- organizations near the house, necessary for the maintenance of domestic sewage;
- pipe assembly and installation.
When laying the pipeline, it is necessary to ensure the necessary slope of the system, which ensures the passage of wastewater by gravity. According to the norms, pipes should sag by 3-5 cm in each meter.
Connection to the central sewerage system
The last stage of work is the direct connection local sewerage to central system. This work should be done only with the personal presence of a representative of the water utility, who can later confirm that everything has been done correctly and complies with the developed standards.
The contract for the sewerage service is signed by the representative of the service organization and the homeowner. According to this document, the volume of wastewater and the fee for its provision are regulated.
Positive aspects of connecting a private house to a central sewer
Connected central sewerage in a private house allows you to:
- save on purchase, installation and maintenance;
- there is no need to control the quality and quantity of wastewater;
- having connected once, you can use the sewer network for a long time, timely and correctly making the appropriate payments.
It is advisable to take care of the choice of local household sewerage and the method of wastewater disposal at the stage capital construction at home. At this time, all connections of devices, pipelines, wells and additional equipment can be made at minimal cost, without spoiling appearance plot and house.
Of course, in a modern home without a well-equipped sewer system today, nowhere. And in any case, it will not be superfluous to find out at least in in general terms: sewerage connection diagrams - what they can be. After all, it is one thing to trust the will of the plumbers and quite another to be able to fix everything on your own if something happens.
What general principles should be followed
Despite the fact that there are a lot of schemes for arranging the sewer system, there are some general principles that can be guided.
Sewerage - component water supply and drainage systems designed to remove solid and liquid waste products
As a rule, in a private house, the sewerage system consists of:
- Central riser;
- smaller diameter: they all get into the riser wastewater;
- Horizontally arranged pipes larger diameter: water flows directly into the sewer through them, treatment facilities etc.;
- Elements plumbing equipment: sink, toilet, bidet, etc.
Traditionally, the kitchen and bathrooms are located in close proximity to each other. This is done in order to minimize the number of joints, pipes to the maximum possible minimum, in order to facilitate the withdrawal of waste water into the system. After all, it is the bathroom and kitchen that account for up to 90 percent of all wastewater.
If we are talking about a multi-storey building, then it makes sense to arrange bathrooms, toilet rooms and kitchens next to each other. In this case, it will be possible to place all plumbing fixtures simply on top of each other, thereby simplifying the sewer construction scheme as much as possible.
Important! If the house has a complex system plumbing equipment, as well as a large number of various branches, then you should think about installing a special sewer pump. This pump may also be required if, for example, it is not possible to provide the sewer pipes with the necessary natural slope.
What you need to consider when drawing up a sewerage connection diagram
In fact, there can be quite a few factors that can affect the drawing up of a sewer connection scheme.
Sewerage - complex engineering structures and sanitary measures that ensure the collection and removal of populated areas polluted waters, as well as their purification and neutralization before disposal.
But in any case, you will have to take into account the following:
- Landscaping features of the site on which the sewer is being equipped. At the same time, it is important that the natural slope of the pipes is ensured. Cesspool should be at the lowest point of the system. Then the wastewater will be able to flow down by gravity - under the influence of gravity;
- Soil type: sandy, clay, etc. This will determine how deep the sewer pipes will have to be placed, how laborious the process of digging the trench will be, and whether it will be necessary to further strengthen the soil;
- Depth of soil freezing. This parameter will affect the nature of the organization of the insulation of the sewer system, the choice of pipe materials, etc.
Of course, other individual characteristics this particular area.
Which pipe material to choose
If in former times the craftsmen were not spoiled by the abundance of all kinds of materials from which sewer pipes could be purchased, now the picture is just the opposite. However, it is the huge wealth of choice that determines its complexity. However, we can safely recommend or polyvinyl chloride. Pipes made from these materials are distinguished by both low weight and resistance to corrosion. In addition, such pipes are easy to install: they do not require the use of welding machine. In principle, even the most novice master can quite easily cope with their installation.
PVC pipes are polyvinyl chloride products designed for the installation of pipelines for various purposes.
Do not be afraid that during the operation of PVC pipes they will begin to emit aggressive chemical substances A: They are completely non-toxic.
However, in addition to pipes, additional devices may be needed in the form of fittings, sewer hatches, connecting rings, adapters, etc. The joints of all these devices will need to be treated with a special sealant.
When choosing the diameter of pipes for sewerage, several factors must be guided. For example, this is the number of plumbing points connected to the sewer. The more of them - so, accordingly, it will be necessary to choose pipes of a larger diameter. Otherwise, the whole system will simply “choke”, unable to cope with the volume of water.
But one way or another, the diameter of the pipe passing from the plumbing fixture must be either larger or equal to the diameter his drain pipe. The diameter of the pipe for the riser must be at least 10 centimeters. If you do not plan to connect a toilet bowl to it, then you can limit yourself to a diameter of 5 centimeters.
The more plumbing points in the building, the thicker the drain pipes should be.
At the same time, the following rule must be observed: the length of the pipe leading from the plumbing equipment to the riser should not be more than 3 meters. As for the toilet, this distance is reduced to one meter. If it is absolutely necessary to increase this distance, then you will have to take pipes with a larger diameter.
The Importance of Preplanning
Before proceeding directly to the installation of the sewer, you need to draw up on paper a preliminary detailed diagram of it. In this case, it is necessary to indicate which pipes of what material, what length and what diameter will be needed in a particular section of the system. All necessary additional devices in the form of splitters, adapters, etc. are also indicated. In the future, this will avoid many unforeseen difficulties during the installation work.
As practice shows, in the vast majority of cases, all plumbing fixtures are brought to one central riser. But, if there are many such devices, or they are spaced apart different rooms, which are far apart from each other, then more such risers will be required.
A properly drawn up sewerage plan will allow you to qualitatively recreate the system, taking into account all the necessary factors.
If the sewerage is equipped in a private house, then the external sewerage scheme should also be included in the plan. Indeed, in addition to the elements internal sewerage, it will also be necessary to provide for the arrangement drain pit, trenches, manholes, etc.
Sewerage connection according to the scheme
As soon as the project is ready, you can proceed directly to the installation work at the facility. Typical scheme for a private house, this will include:
- sewer riser;
- Toilet, washbasin or sink, as well as a bathroom;
- Siphons for all these plumbing fixtures;
- Flush tank for the toilet;
- Attaching couplings to the wall;
- Connecting pipes running at some slope to the riser.
Of course, if necessary, this scheme you can change it at your discretion, but the typical picture looks like this.
A siphon is an element of plumbing. It is a pipe bent in several places, through which water is drained into the sewer system.
The sewer riser is connected to the pipes using horizontal pipes of the same or even larger diameter than the riser. Pipes can be placed in the basement, in the basement or under the floor. It is also necessary to provide for the presence of revision wells, which are required at the places where the pipes turn.
All pipes of the system must be connected into one single pipe. large diameter, which, in turn, is removed from the house and docks with the external sewer system. Sewer pipes are attached to the walls with special clamps.
Options for tapping the sewer system of the house into the central system
If there is already a centralized sewer system outside the house, then there are several options for how you can join it:
- Insertion with a tee;
- Insertion with adapter.
In the first case, you will need to cut a piece of the main pipe and build a tee into it. The tee itself is fixed on the pipe with the help of a coupling, then all joints are welded.
More modern version can be considered a special adapter. It also crashes into the main pipe.
A pipe tee is a piece with three gaps that connects the components of the pipeline and is installed at the points of its branching.
In any case, it will be necessary to block the central sewerage and, of course, obtain permission to carry out mortise work. Otherwise, you can not avoid a rather large fine. The law even provides for imprisonment in case of unauthorized connection to the central sewer.
What the experts say
Vladimir, service company employee: Many people forget to get written permission from their neighbors before starting work. In the future, this can turn into many difficulties and conflicts. So in any case, it is better to take care of their consent to sewerage in advance. As for the magnitude of the slope of the pipe, the rule works here: for each meter of the pipe, the change in height should be from 2 to 15 centimeters.
Anton: All elements of sanitary equipment must be equipped with S-shaped or U-siphons, which would provide a natural water seal for unpleasant odors that could get inside the house from the sewer.
Outcome
In principle, laying sewerage on your own is not so difficult task. It is facilitated by the fact that in the overwhelming majority of cases one can be guided by standard schemes to connect. But, faced with unforeseen difficulties, do not be shy to ask for help from qualified craftsmen.
.
In the process of building a house, it came to sewerage ... In the technical conditions issued when obtaining a building permit, it is written simply and without fanfare - "waterproofed sump." But I don’t really want to call vacuum trucks every month, or even earlier. Neighbors, who, by the way, have the same thing written in the TU, made it even easier - 3 1.5-meter rings WITHOUT A BOTTOM ... Like, there are no wells nearby, water from the water supply, the neighbors above generally pour almost into a ditch. .. Again, no one will dive there if suddenly the SES is checked. And it's unlikely, to be honest. But this way somehow disgusts me ...
In short, he began to think, count, consult with everyone. One of the colleagues suddenly asked - "Do you live in a deaf village?" It seems not a village (a settlement of regional significance in Yaroslavl region). "Do you have a sewer there?" "Well, of course, we have a whole bunch of five-story buildings." "Here, connect to the central one, don't be wiser!"
This conversation, as they say, sunk into my soul. "Why not?" I think. I went to our glorious housing and communal services department, or whatever it is called. They were very happy and surprised. We say that we are always happy to support the initiative of the residents, we will help in any way we can, in addition, we will only connect to this pipe later with your permission (and there, in principle, many people can be connected). Here I must say about the location of my house. On the hastily made a little plan.
My house is highlighted in black. The existing sewerage system is in bold. Accordingly, I had two connection options - 1. To the well, which is 200m away, 2. To the well, which is 150m away. Naturally, the shorter the better, especially since the pleasure is not cheap - 1000 r / m + every 50 m well, its price is about 10,000 rubles. But the slope, as can be seen from the diagram, is towards my house. And it is more logical to connect according to the first option. So I was told in the housing and communal services. There is a natural slope in that direction, there is a field - dig - I don’t want to. I agreed with two neighbors, so the amount divided by three did not seem so big anymore. Moreover, there are a couple of houses under construction on the way of the proposed sewerage, so there is hope that they will be connected in the future ... In general, in the housing and communal services, we agreed that closer to the beginning of November (it was in October), we conclude an agreement with them and they lay everything before winter.
In the first days of November I come to the housing and communal services. And then they tell me - our master went to your site, measured everything, in principle, you can connect to another well (up to which 150 m), there is a slight slope in your direction. And here are solid pluses - 150 m instead of 200 m, there are a whole bunch of neighbors with whom you can share the costs, beauty. Well, let’s dig there, I say, I don’t mind, as long as it doesn’t freeze, otherwise it doesn’t turn out deep. No, what are you saying, we have been doing this for a long time. Over there in G ... they generally made 250 m of sewage on the surface - it doesn’t freeze! (Wizards, damn it!). In general, I gave an advance payment of 70,000, concluded a "contract" (such a pisyulina, I laughed to tears, but that's another story). Well, in general, they started work after 3 days.
They dug something there for half a day, then I decided to go and see what was going on there. Just then their chief engineer is going there. On the way, he tells me that the master did something wrong, it turns out that the pipe will pass a little higher. But that's okay, throw snow on it in winter, and that's it. We arrive - the picture is this: from the existing well, into which a tie-in was made, about 40 m have already passed (according to calculations, there should be the first new well there) to my house, respectively, about 100 m. And the pipe is already 40 centimeters from surfaces. The engineer tells me - well, the master did something with a big slope of the pipe, he made a little mistake (although I also came during the laying - they scalded almost without a slope). But allegedly closer to my house there will be a rise in relief, but here it’s just a pit, they will bring soil, throw it in.
Well, let's dig further. Another day tinkered. The delivery of soil was expressed in what way - I had heaps on my site after the foundation was built - you can, I say, take them, level them all the same. Here is one pile and leveled - about the volume of a car. Thank you anyway.
Then the director of the housing and communal services of this calls me - come, she says, we can’t do anything here. I arrive - she begins to rub me - you need to raise the site, it is low, your foundation is low, you will still raise the house - and. etc. In general, at first they told me that the pipe would come out of the ground 50 cm below the level of my foundation. In principle, it’s tolerable, it’s better to insulate it, if the connection from the house is not very long, you can ... Then they say - they say, 10 cm lower than the top of the foundation (level with the ground - they said so, but in reality, I think, there would have turned out to be an aqueduct).
In short, doubts loaded me. We agreed with them - the work was stopped, I will think, I will advise how I should proceed. I was already thinking about making a pressure line from the house, or pouring it out there immeasurably. In the end, I brought to the site two more or less knowledgeable people 9, including the one who advised a colleague))). They, only looking at the first well made by the mountain masters, before reaching my house, offered to send them to a known address. Regarding whether it will freeze or not, my colleague suggested to pee directly into this new well and see. Now, he says, the temperature is about minus 1, and then it will freeze (the depth of the well there is no more than 30-40 cm).
In short, they decided to return the money. True, the contract was like this - we will take 5-7 thousand from you, but we bore the costs .. Choke, I think, you still have to hire a tractor, connect electricity, etc. in short, quarrel with you ... As a result, they returned money minus 6000)))). So I was left without a central sewer.
By the way, there was another connection option there, everything is fine with a slope, where the length is longer. As the problems started, I suggested to them - let's connect there? After all, they themselves wanted to be there first. In no way - there is a quicksand, sprinkle too much rubble, it will turn out expensive, in general, we will not do it there, make a sump. The question, why was it offered there at first, remained unanswered ...
Now I'm thinking about how to make a septic tank ...
Arrangement of sewer systems is perhaps one of the most expensive (in the field of finances, time and nerves) work areas. But it is impossible to do without sewerage. Especially if you plan to live in the house permanently. Sometimes it is more profitable to connect a cottage to a central sewer system. In situations where the house is located in the city. How does a sewer connection work? Who should I contact and what documents do I need to complete?
Tapping into the central sewer: an economical and legal approach
Intrusion into any utility systems (heating, gas and water supply, wastewater disposal) must be carried out with the permission of their owner. Illegal tapping into the sewer is only extra waste financial and time resources. You will have to pay a fine and dismantle the unauthorized section of the system at your own expense. Therefore, it is better to do everything legally.
1. Find out which organization is engaged in the disposal and treatment of wastewater in the area adjacent to the house.
2. Collect the necessary documents and carry out preparatory work.
3. It is legal to connect to the city sewer.
Now let's take a closer look at each stage and outline the options for savings. Money.
Walking through the authorities, collecting pieces of paper, signing them, agreeing can be entrusted to a specialized company. But for this you will have to pay a tidy sum of money. If you do everything yourself, then save.
Can also be found the right words and an iron justification for contacting the water utility with a proposal to improve the sewer line adjacent to your house. The task is to convince city services of the benefits of this event.
You, as the owner of the house, do not have to call a surveyor, agree on a connection plan, register it with the right authorities. All you need is your financial help.
Vodokanal will be able to modernize one of the branches of the central sewerage system and improve its reporting. This event is beneficial for both parties.
Another way to save is a collective tie-in to the central sewer. Talk to neighbors. Perhaps someone also wants to connect to the city sewer. It will be more profitable to do it at the same time.
Preparatory work
How to prepare for a tap into the sewer system of the city?
1. Install an inspection well on the site.
It is needed for routine inspection, cleaning and maintenance of the sewer branch. Without a revision well, they will not be allowed to connect to the central system. Since problems in your branch can lead to the failure of the entire sewer.
2. Connect internal system sewage disposal with a revision well.
Sewer pipes that go from the house must lie at a depth of at least one hundred and twenty centimeters. The slope of the sewer per linear meter of the pipeline is five millimeters (approximately). If you tilt the pipe less, the risk of blockages increases. If you make a slope of more than seven millimeters, the wear of the pipes increases.
Insertion into the city sewer
When all the preparatory work is completed, it is necessary to inform the service sewer network company about their desire to connect to the sewer.
The connection procedure consists of several stages:
1. Call a surveyor.
The specialist examines the area. He will develop a situational plan, which will indicate the plan of the house and the plan of the future sewer branch.
2. Applying.
An application is submitted to the sewer service company with a request to develop individual technical conditions for wastewater disposal.
3. Registration and approval of the project for entering the central sewer.
You give the finished situational plan and technical specifications to the designers. Based on them, a project is being drawn up for entering the central sewer network. This document must be approved by the water utility and the architect. The latter must also give permission for connection work by one or another organization.
In some cases, permission from neighbors may be required to conduct repair work next to their sites. If a new sewer line crosses the pavement, a permit from the road maintenance service and the motor vehicle inspection will be required.
When all work is completed, the water utility must be notified of the launch of the line. The company servicing the sewerage network accepts the completed project and concludes a contract for the collection of wastewater.
If the central sewer pipeline is located above the site where the house stands, a pressure sewer must be equipped.
On the site determine the location of the receiving well (2). Equip it according to the principle of the simplest septic tank. Waste water from the house (1) enters the sump of the receiving well (2 a). The effluents cleared of large suspensions flow through the grate (9) into the pumping tank (2 b). A pump (10) is installed here, which will transport wastewater to the general sewerage system (8). The pump power depends on the following conditions:
- pressure line length (6); this is a pipeline that removes effluents from the site;
- the magnitude of the rise of effluents (how low is the site relative to the central highway);
- number of stocks.
The pressure pipeline leads to a manhole (3). From here, wastewater will flow into the city network by gravity (7).
The arrangement of a pressure sewer is possible for several neighboring houses at once. The receiving well is made common. Accordingly, its dimensions and pump power will be larger. If such work is planned, it is better to connect your house immediately. Subsequent unauthorized insertion into the sewer can lead to overcrowding of the receiving well, to a breakdown of the pump, to problems with neighbors and heavy fines.
Methods for inserting into a sewer pipe
How can I connect a branch to an existing sewer pipe?
1. Through a tee.
Saw and cut a piece of existing pipe. A tee will be installed at this location. Therefore, the dimensions of the sawn piece must correspond to the dimensions of the tee.
The tee is put on pipe segments using a coupling. The joints are welded.
If you want to connect to the system from plastic pipes, then one pipe is replaced by two segments. And between them they insert a pipe to connect an additional branch. The preparation of a pipe section with a branch pipe is shown in the diagram:
2. Through an adapter.
Modern transitional device. To connect to the sewer through the adapter, perform the following steps:
- blocking the water in the system;
- put a crown on the drill suitable diameter and make a hole in the pipe with it;
- if the adapter is with bolts, then it is pulled onto the pipe and the bolts are tightened;
- if the device is without bolts, then the surface is degreased, a tie-in is applied and the nut is tightened.
Sidebar in sewer pipe must be carried out by experts. Since the serviceability of the system, the absence of leaks during operation depends on its quality.
