The installation of sanitary systems is carried out according to the working installation drawings and in accordance with the current Construction Norms and Regulations, the project for the production of works (PPR), containing technological maps and operational quality control cards.

The set of technical documentation includes: the title page of the project and floor plans (plans at different elevations), attic and basement plans, sections of buildings with the indication of sanitary equipment and pipe: wires; axonometric diagrams of systems or sections (for the sewage system and drains of residential and public buildings); drawings of water and heating inputs with control units; drawings of non-standard units of sanitary devices with a callout of individual complex parts; typical drawings referred to in the project; drawings of underground channels; plans, sections, diagrams of a heat point, boiler room with an indication of equipment and foundations; plans and sections, diagrams of individual installations; specification of equipment and materials; estimates; explanatory note; assembly drawings of pipelines of internal sanitary systems developed by the design organization.

When laying intra-quarter networks, the set of technical documentation also includes the general plan of the structure, profiles for external networks, drawings of structures on the networks (cameras, wells, etc.).

Technical documentation is considered in the VET (production and technical department) with the involvement of foremen, foremen and workers. Particular attention is paid to the possibility of using more economical and rational solutions that reduce the complexity of work, the need for equipment and materials, the maximum use of standard and standard parts, and to ensure safe working conditions. After reviewing, making the necessary changes, coordinating them with the design organization and the customer, the technical documentation is approved by the chief engineer of the department, after which it is transferred to production. Having received technical documentation, the foreman introduces the installers to it.

On the basis of technical documentation, a work production project (PPR) is developed, consisting of calendar plans, network schedules of work, which indicate the scope of work, the need for materials and equipment, orders for the manufacture of assembly units and parts, process cards for processes that do not have standard solutions, safety measures.

In the working drawings of sanitary systems developed by design organizations, the level of detail is insufficient for their factory manufacturing. They do not bind elements to building structures. Therefore, they carry out installation design.

For typical buildings constructed from large prefabricated elements that have slight deviations of actual sizes from design, installation design can be performed on the basis of working drawings of sanitary systems and construction drawings developed by the design organization. In non-standard buildings, the actual dimensions of building structures can have significant deviations from the design. In this case, the installation drawings are developed on the basis of measurements in kind of those elements of the built building that determine the necessary dimensions of the mounting units of the sanitary systems. This method of installation design provides high quality mounting blanks.

When developing assembly sketches, drawings and measurements, the following concepts are used:

• a part (1, 2, 3 in Fig. 40) - a part of the pipeline that does not have connections (pipe section, transition, branch, tee, flange, etc.);

Fig. 40. Node (a) and block (b):
   1, 2, 3 - details

• element - a part of a unit consisting of two or three parts connected by welding or on a thread (pipe with a flange, pipe with a tee, pipe with bends);
• node - the layout of several elements assembled together using detachable and integral connections; the unit also includes standard and non-standard parts;
• block - two or more nodes interconnected by means of detachable and one-piece connections;
• the mounting position of the device, equipment, pipeline - this is their location relative to building structures and other equipment, which ensures ease of installation and use of them, as well as safe operation;
• construction length / page - a size that determines the position of a piping part or assembly with respect to another adjacent part or system equipment, for example, the distance from the riser axis to the axis of the device or the distance between the centers of the connecting parts;
• installation length / m - the actual length of the part without connecting parts and fittings; the assembly length of the part is less than its construction length by the amount of skid x - the distance between the axis of the connecting part or reinforcement and the end of the part screwed into it;
• procurement length / zag - the total length of the pipe segment required for the manufacture of the part; for straight, without bending parts, the installation and procurement lengths are equal; procurement lengths of curved parts are determined depending on their type.

Measurements in kind are carried out by highly skilled measuring workers or technicians who are part of the production preparation group. By the time the measurements are taken, the object must have mounting readiness. For measurements, a Hume length tape measure, a folding metal meter, a building level, a plumb line with a 15-20 m long cord, a wooden batten measuring 1500 x 40 x 20 mm, a protractor with an angle meter, universal templates, colored pencils or crayons are used.

Measurements begin with the marking of the installation positions of the devices (heating, sanitary), the axes of the risers and pipelines in accordance with floor plans and axonometric diagrams of the project. The mounting positions of the devices are marked on the walls. The axis of the riser is marked using a plumb line with a cord. To do this, the worker, located on the top floor, lowers the plumb line into the hole in the ceiling and places the plumb line in a place convenient for mounting the riser. Another worker, being below, checks the possibility of installing the riser along the intended vertical and indicates the axis of the riser. Applying the cord to the axis of the eyeliner and the branch point from the riser, outline the axis of the pipelines. Measure the building length and put its values \u200b\u200bon the sketch, on which the assembly unit is depicted in axonometric projection, the diameters of the pipeline sections, connecting parts, fittings, connections are indicated.

Then the sketches are processed and on their basis the installation drawings and specifications are developed. In this case, the installation lengths of the parts are determined, which are shown in Fig. 41 are indicated by numbers, and procurement, indicated in the figure by numbers in circles.

Fig. 41. Sketches of measurements of pipelines:
  a is the plan; b - sketch with measurements of building lengths; in - processed sketch, conventionally divided into blocks I-VI; 1 - devices; 2 - risers

Pipelines are divided into nodes and blocks so that their mass and overall dimensions are convenient for installation, loading, transportation, posting on floors.

Sketch drawings are drawn up and applied to orders, which are drawn up in four copies: two are transferred to the procurement company, one to the assembly department, and another is stored in the control room.

Do you want to seriously repair and renovate the apartment? Then it will not be amiss to find out that one of the most basic stages of the overhaul of housing is the replacement of old plumbing and pipes with new ones. In addition, this is the most impressive expense item in the budget allocated for these works.

To reduce the already impressive costs is the normal desire of every prudent owner. Do you agree? It is quite possible to reduce them: do-it-yourself installation of plumbing will help. We will tell you how to make wiring, how to transfer and connect plumbing equipment, what tools and materials are needed.

You will learn how to independently change the pipes in the bathroom and connect plumbing fixtures. And in order to make it easier to understand the repair issue, the article provides thematic photo guides and video instructions.

Typical designs of high-rise buildings are not suitable for everyone, and the owners of the apartment try to remake the plumbing according to their preferences. This set of works is very troublesome and time-consuming, however, if you study the theoretical side of the issue well and follow the instructions exactly, most of the work (if not all) can be done independently.

Which is better: serial or collector circuit?

Today, two generally accepted ones are used - serial and collector.

A sequential (or as it is also called plumbers - tee) system is considered classic. It is used in all typical apartment buildings and private houses with small bathrooms.

The system is very simple - from the central risers, through which hot and cold water is supplied to the apartment, it is laid under one main pipe, from which each plumbing fixture in the apartment is powered.

For each device, a tee crashes into the pipe. Thus, the entire length of the pipes in the house or apartment is relatively small, so this type of wiring is considered the most inexpensive

The amount of work on installing plumbing for a bathroom with your own hands is also not very large. However, the benefits of a sequential circuit end there. The main drawback of this type of connection is that all devices are powered by one pipe, and when one device is working, the pressure in all others drops.

That is, when the washing machine pumps water, the pressure in the kitchen faucet will be very weak, and vice versa.

Another disadvantage is the shutdown method. If one plumbing fixture breaks, then in order to repair it, you will have to completely shut off the water in the apartment. The collector system is used in those houses where there is a large load on the water supply system. In this case, all plumbing points are connected to the collector.

The collector is a large diameter distributor having a certain number of outputs. A separate tap is installed on each output.

Most often, the collector is hidden in a special cabinet or a closed niche - for aesthetic reasons. Each plumbing fixture is connected to the collector separately, through a personal tap. With this method of connection, a large number of pipes will be required, and installation work will take a lot of time.

Although you will have to tinker with connecting such a system, the advantage is obvious: the pressure in all plumbing devices will be stable under any mode of operation of the water supply system.

In addition, each device can be disconnected or dismantled if necessary. At the same time, there is no need to completely shut off the water - it is enough to turn off the tap on the required branch.

The assembly of the pipeline from polypropylene pipes has its own tricks, which should be closely monitored:

How to connect a regular sink?

Focusing on it, we mark a horizontal line on the surface of the wall. After that, you need to measure the width of the back wall of the washbasin and put this distance down from the mark.

Before attaching the brackets to the wall, you need to accurately calculate the distance between them. It is not difficult to do this: we turn the washbasin over, put the brackets on top so that they fall into special grooves. Next, measure the distance between the brackets and transfer it to the wall.

Now you can make holes, beat dowels, tighten the bolts. Next, you need to install a mixer on the sink, then fasten it with bolts and washers, check the location of the sink by level and fix it with nuts.

We install a rubber gasket on the drain hole and mount the drain, connect it to the siphon. Using an adapter, we connect the drain pipe of the siphon to the sewer. Using flexible hose-tips, we connect hot and cold water to the mixer.

How to install a sink on a pedestal?

In this case, it is very important to make the markup correctly. We put a pedestal, on top of it we install a sink so that the drain is exactly in the center of the stand. We check its location using the building level.

The process of installing a sink with a pedestal is not much different from installing a conventional washbasin: in addition, we mount an element that disguises the pipes under the sink

After that, carefully mark the location of the mountings for the bowl on the adjacent wall. The entire structure can be temporarily disassembled to make holes in the wall. After that we beat the dowels, twist the screws, put on the gasket nuts.

Now it remains to fasten the washbasin to the wall. The main thing here is not to overdo it, as the ceramics can crack if the nuts are clamped too tightly. Inside the pedestal, you need to install a siphon and connect it to the wash basin, and the drain pipe to the sewer.

In order to visualize the installation process of the sink with a pedestal, we suggest that you familiarize yourself with the following selection of photos:

Image Gallery

After installing the pedestal in the place of the intended connection and installing a sink on it, we check the horizontal level of the device at the building level. Carefully hammer the dowels into the drilled holes using a rubber mallet through the plank. We twist the brackets in them; we connect the sink to the outlet into the sewer system by connecting a siphon to its drain

Stage 2: Marking the attachment points of the plumbing fixture

The most popular toilet model is the floor. If the floor in the bathroom is faced with ceramic tiles, you need to put something soft under the toilet - for example, a piece of linoleum or rubber. To connect the toilet to the sewer, you need to use a special cuff. One end is connected to the toilet, and the other to the sewer pipe.

The toilet is attached to the floor with special studs that are inserted into dowels fixed in pre-made holes.

The toilet is usually sold pre-assembled. You just have to attach it to the floor and connect it to the water supply and sewage system.

In some cases, the toilet adheres to the floor using epoxy adhesive. In this case, the toilet should not be used for approximately 12 hours until the glue completely hardens.

After reading this article, you will learn how to correctly and quickly display the sewer, water supply and heating system on an axonometric diagram.

How to reflect all communication elements in a drawing

In order to cope with such a task, you need a program to create graphic drawings, sketches and diagrams. You can open any of the arsenal of construction programs supplemented by such a function, or one with which you are familiar.

Before developing a perspective view, prepare an apartment or other room with communication networks.

Drawing everything is not so difficult, especially if you have experience working with engineering programs. The sketch reflects all the pipes shown on the plan of the house. They are transferred to the electronic version of the axonometric scheme and reflected at an angle of 45 degrees.

Important! This rule does not apply to horizontal sections. The lines are left unchanged.

Like designs in electronic version

The fastest way to build a drawing is by cloning the entire circuit. To do this, select the "Insert" command, after which the integrated image is turned over. For the function to execute, it is assigned a value equal to 45 degrees (a number is written in the program).

Having prepared the basis in electronic form, where risers are marked on the plan, they put symbols in the form of dots. A vertical line is drawn to reflect all floors in the building. For the purpose of better perception, overlap panels are reflected in the diagram.

Important! Do not make plates too long. Use the gap.

A feature of the axonometric scheme of sewerage is the reflection of all elements of sanitary devices: urinals, toilets, sinks, drains and other devices for hygienic procedures.

What is reflected in the diagram?

The axonometric figure of the sewage system necessarily shows:

1. The entrances of the house.
2. Distribution system wiring in the building (risers and branches from them to each floor).
3. The locking and regulating elements of fittings.
4. Adapter rings for pipes with different diameters at their joints.
5. Descent points from the system (tees with plugs).
6. Cranes: watering and fire stations.
7. Sewerage equipment, water metering points, instrumentation and other components of the sanitary and water supply branch.

What data contribute to the drawing

The introduction of the following indicators describing the water supply system is mandatory when constructing an axonometric diagram. Such information includes:

1. The designation of the risers (usually the area of \u200b\u200bthe leader line).
2. The floor level of each floor of the room, the boundary of the horizontal branch (at the axes of the pipeline), the height of the points of drawdown (marks along the risers).
3. Diameters of system elements.
4. Slope angles of pipelines (with indication of slope).
5. Dimensions (length) of each of the independent sections of the pipeline, which include risers and horizontal branches in millimeters.
6. Coordinating sizes (information of a secondary nature).
7. Designation of nodes in order to detail the drawing.

In addition to a number of basic data, accompanying documentation is attached to the schemes, including the specification for materials and equipment.

Sketch Design Features

Here, attention is focused on the reflection of devices. If one element climbs onto another, and this happens in most cases, then a dotted line indicates the displacement of the plumbing element in order to better visual effect.

The axonometric diagram of the water supply should include indications of all pipe diameters. If the toilet is not marked on the tap, then take a diameter of 50 mm, if it is, the minimum diameter should be 100 mm. These numbers are important to remember. For risers in 90% of cases, an indicator of 100 mm is used. Slopes in the same diameter will be 0.02, with an indicator of 50 mm, the slope is set to 0.03.

If you have already applied all the elements, mark the outlets, the diameter of which is larger than that of the risers, they take the number 0.02 as a slope.

At the last stage of drawing up the axonometry, special marks are made based on the characteristics of the site and the construction plan. Here they note the level of freezing of the soil, the location of the foundation, as well as other factors affecting edits.

Features of the drawings

When designing an axonometric diagram, pay attention to such points:

1. Plumbing and other devices connected to the risers and distribution network, reflect only when the necessary documentation is not necessary schemes.
2. The zero mark (level of the first floor) is shown on risers, drawing a thin horizontal line. In the case of a detailed project, each of the nodes in the drawing is considered separately, reflecting it on an enlarged scale.
3. If necessary, the sketches of diagrams and drawings of water supply networks and sewerage make the legend of shut-off and control valves, watering taps and other system elements.

Axonometric drawings of heating and ventilation branches

When working with utility networks, calculations and graphical visualization act as important components of work on a project for the construction of a residential building. In addition to the plan of the house and its facade, the package of documents required for construction is supplemented by an axonometric diagram of communications. On it you can clearly study a particular network: water, heating, ventilation. Especially relevant is the use of such drawings in the arrangement of complex systems. A perspective view of the heating project simplifies the work of installers in the process.

What to look for when building a sketch

Before reflecting the axonometric scheme of heating the premises in paper or electronic form, a number of calculations are performed. The scheme itself is based on the collected data:

• heat demand values \u200b\u200bfor the rooms of the building;
• typologies of heating devices, their quantity for each of the rooms;
• basic decisions regarding the entire engineering network: the use of risers, the calculation of hydraulic branches and circuits, the procedure for connecting elements of the heating system;
• characteristics of pipeline sections: diameters and lengths of pipe fragments, valves, thermal controllers, hydraulic regulators.

Having received the corresponding calculations, their indicators are entered into the scheme. Axonometric necessarily contains the technical characteristics of each network node (boilers and used pumps), pipe length and diameter, heat consumption and information about other thermal properties of heating devices, such as radiators, convectors, registers.

Starting to work on an axonometric drawing, first of all, the main ring of coolant movement is determined - the path to the most remote element from the boiler and vice versa.

Summarizing what has been studied, let us say that axonometry is performed without fail, regardless of the type of communication system for structures of any type of purpose. Having a graphic drawing before their eyes, installers quickly determine how much work to be done and how exactly the network looks.

If a specialist understands axonometric and the drawing itself is done correctly without any errors, then during the project execution it is possible to exclude the occurrence of any difficulties associated with the installation of heating system elements, piping and other engineering networks.

In order for the design, and then the installation of the water supply, to be successful, it is necessary to correctly visualize the building itself and the communication branches inside it on a sheet or in electronic form. In this case, the graphic component of the project includes:

• general plan of the building;
• situational scheme;
• facade;
• plans for each floor;
• roof plan;
• axonometric schemes: ventilation, heating, water supply;
• cuts and other concepts.

Remember that when working with a correctly designed axonometry, there are no problems with 99.9% of cases. Therefore, this stage is so important in the design of the future home or apartment building.

Hot and cold water pipelines, drains, sewer systems, gas supply networks, ventilation and air conditioning systems, as well as heating systems are sanitary systems and engineering equipment of residential, industrial and public buildings.

In order to equip buildings for various purposes with engineering and sanitary systems, a set of working drawings is developed and compiled. It includes:

Plans and sections of installations

Plans, sections, and axonometric diagrams of systems

General data of water supply, heating, sewage, ventilation and air conditioning systems

The main components of engineering and sanitary systems are:

Pipelines (risers, horizontal lines and connections to devices)

Pipe fittings (valves, taps, gate valves, valves, etc.)

A variety of equipment (pumps, filters, air conditioners, water heaters, etc.)

The basis for drawing up drawings of engineering and sanitary systems of buildings and structures is the information contained in the architectural and construction drawings, on the sections and plans available on them. It contains graphical images and layouts of pipelines and pipe fittings, as well as reamers, profiles and sections of walls, which depict both the elements of engineering and sanitary systems, as well as the connections that should be between them. For a more clear and understandable image of the most complex nodes, some fragments of sections and plans are performed on a larger scale.

Axonometric diagrams made in frontal isometry show the most complex and most branched networks of plumbing, heating systems and gas supply systems in their design. Moreover, for individual sections of pipelines indicate the values \u200b\u200bof such quantities as the diameter, direction and length of the slope, as well as the length of the section. Specifications for equipment and materials are attached to the working drawings.

According to accepted standards, conventional graphic symbols are used to depict various elements of sanitary systems in the diagrams and drawings. In the special tables, those designations are given that should be used to image both the pipelines themselves and the fittings used in them on axonometric diagrams, reamers, sections and plans of engineering and sanitary systems of buildings.

According to GOST 21.601 - 79, a solid main line is used to draw conditional graphic elements of pipeline systems, and those parts that are invisible (in channels, underground) use a dashed line of the same thickness. A thin solid line is used to depict process equipment and building structures.

If it is necessary to draw the sizes of the conventional signs of pipeline valves (valves, valves, etc.), then their sizes are taken equal to 3-3.5 pipe diameters. Elements of networks and sanitary systems are supplied with special brands (alphanumeric designations).

The table below shows the conditional graphic elements of pipelines GOST 2.784 - 96.
