Installation of sewage from plastic pipes held in private and apartment houses, administrative buildingsequipped with a water supply. The drainage systems are divided into local and centralized. In one room, the wiring consists of blocks, each of which consists of 3 lines - from toilet bowl, bath and kitchen sink. During the arrangement of the highway, parts of different lengths, diameters and configuration are used. Consider what nuances should consider when designing and assembling the pipeline with their own hands.
Principles of sewage installation of plastic pipesWhen planning the laying of new communications for drainage, it is necessary to pay special attention to the choice of quality material, fixtures and components. It is recommended to purchase goods from a proven supplier who has a certificate for its products. It is better to buy products issued by one manufacturer. This will avoid difficulties in fitting and connecting parts.
The basis for calculating is the scheme on which such data is displayed:
The material is desirable to purchase 10-15% more from the calculated one. In any work, marriage and errors are possible. In addition to plastic products, it is necessary to buy silicone-based lubricant. It is best suited for connecting fragments of the highway and ensuring its tightness.
When choosing a material for sewage arrangement, most of the masters are inclined in favor of using pipes from polymer plastic. A similar solution is substantiated by many positive characteristics inherent in this product of the petrochemical industry.
The arrangement of pipeline polyvinyl chloride has such advantages:
Polymer communications do not need regular maintenance and repair.
To pave the drain pipeline, it will take special equipment for laying the channel of the desired configuration in the floors, walls and furniture.
It is necessary to use such tools and devices:
Preparation for the installation of sewage starts with the application of the horizontal line from the tee inlet to the riser to all consumers of water. After that, every 50 cm makes marks corresponding to the necessary slope. In order not to be mistaken, with the assembly, the backups are put on which the pipes will be laid. The holes are drilled in the walls in which the clamps are installed with the appropriate pipes with a diameter. In completion, drill holes, clearing the bed and removal of the construction trash.
The features of the sewage arrangement are that the basis of the functioning of the domestic sewage is the power of gravity. Vital products are moving through the channels by self under the influence of gravity. In order for the drains from the water consumer in the riser, all lines should have a bias of 1-1.5%. Thus, with a line length 200 cm, the height difference between the tap and the pipe output into the overall stock should be 2-3 cm. For each turn, 1 cm is added. If you do not comply with these rules, the highway will be constantly clogged by waste.
The next nuance is the selection of the correct size of the section and the configuration of the highway.
Select plastic sewer pipes of this diameter:
Since the largest waste is coming from toilet bowl, the distance from it to the riser should be minimal. If the pipe laying will need to change their direction, then it is better to do it with the help of taps under 45 °, as cool turns can be clogged.
A feature of the products made of polymer material is the change in their size under the influence of temperature. So, when it increases by 1 °, an increase in the length of the link is 0.5%. This must be taken into account when carrying out calculations, so as not to set turns back to the walls. You always need to leave 1-2 cm of stock for damper expansion links. Minor curvature on strength and tightness does not affect.
When cutting blanks, it is necessary to check that the pipe diameter corresponds to this indicator of fittings used when laying communications. Technical indicators are applied on the products themselves, but it is better to check them in advance, even before the start of the assembly. It should be remembered that the density of the compound and tightness is achieved through the use of pads. The difference between the inner and outer diameters of the connected links is 2 mm. Minor backlash allows you to compensate for minor errors made by design, making markup and assembly.
Consider the features of the compound of plastic pipes. They are performed using the skin, inside which rubber gaskets, rings and cuffs are installed. Dual gaskets with a plastic ring are considered the best in terms of durability. They are hard to collect, but the applied efforts pay off reliability and durability of the junction. Before connecting parts, it is necessary to make sure that the gum proper form, tightly located in the squabine sinus and not overwhelmed. If the product is defective or damaged when assembling, it should be replaced with a good part.
Fastening sites are the weak points of the pipeline. Over time, the gasket material is screwed and decreased in volume. To slow down this process, it is necessary to use high-quality lubricant with a preservative effect. Soap and car oil does not fit for this. These substances cause corrosion of rubber. Professionals recommend using silicone lubricant.
The edges of the scaled pipe must be cleaned to get a chamfer. After the segment is inserted into the socket, it must be moved forward until it stops and go back to 10-15 mm.
When installed sewer pipe It is recommended to follow these rules:
In compliance with the rules of calculations, applying markings and assembly The sewer system will last no less than the structure itself.
The cottage has erected or repaired, it remains to build a removal system wastewater, water pipes. Call plumbing masts, not everyone can trust. To make the installation of sewage from plastic pipes, water supply, enjoy the work done, save money.
Independently carry out work on plumbing, without experience scary. It is necessary to know the rules and tricks to build a working structure. To home masters will be useful to learn about the work stages whereby attention.
The choice of polymeric materials is justified. They possess a number of advantages:
Internal sewage displays all wastewater beyond the borders of the house or apartment, and the outer sends them to the place of collection or cleaning. Industry produces several types of plastic sewer pipes:
In addition, the knowledge of the nuances of the installation sewer systemIt is necessary to be guided by the recommendations that are prescribed by SNiP 2.04.01-85, this will avoid gross mistakes.
Seven times measure cut once!The collected design is necessarily checked at maximum load, simultaneously inspect the joints.
Installation of sewage in the apartment, a private house, begins with the internal system. The order of work is the same:
New sewage layout is composed. Count: Length, diameters of the required pipes. The number of connective, transition, fasteners, cuffs. Each device requires a siphon that will not allow to penetrate the inside of the room with a unnecessary smell. So that fecal waters do not penetrate into the sewer system, the toilet is set first to the riser. Be sure to place an audit trick, for cleaning or checking. According to the scheme, consult from specialists.
Plan the length of pipe pipes to cut less. It is best to go to where the purchase of component parts will go through, find out the nomenclature.
Seasoning device - Samotek. From the very far point of the drain, the highway is placed to the riser, passing Plums will be connected to it. Subtleties:
A private house requires a supply to external sewage. In a multi-storey - remains to connect collected design To the riser.
The withdrawal of plastic sewage from the cottage is protected by a galvanized sleeve, protecting from external damage.
For external sewage, a cross section is 110 mm. Corrugation has greater strength. In the ground, the highway must be below the level of soil freezing - this is 1.5 - 2 m. It is sprinkled with a pillow of a mixture of sand and clay, reducing damage. If it is impossible to pave so deeply, it is insulated mineral Vata..
After connecting the sewage, water supply is supplied.
A diagram of connecting all elements is drawn. For hot water, 10 mm technological clearance is left, since the plastic from heating expands. After, the total length of the highway, the necessary fittings, is calculated. The number of shut-off, fasteners. To subsequently add new devices, it is recommended to leave several taps with plugs.
Planning the water supply is important to know that plastic pipes are made of gray. Their marking:
Where the water temperature below 60o, the first two points will be suitable. If the temperature is higher, then the third, fourth options are used, as they are reinforced.
To save time, ensure control over the state of the water supply, it is better to apply open scheme Connections. Pipes are installed at the floor level, at the corners of the room. Model option, it is the easiest - consistent water supply to all consumers. To repair without turning off everyone, before each, install a shut -tented valve.
Step-by-step instruction soldering plastic pipes Details purchased, the tool was prepared, it became possible to solve the question of how to mount the plumbing. According to the scheme, the pipes of the pipe are cut with special scissors. They are connected using fittings or. Technology Simple:
Design elements are fixed to the wall with clips. Rims - with the help of a clamp and rubber gasket.
Additional elements like valves, counters have a threaded metal compound, it is sealed to the pass. Professional plumbing prefer to use fluoroplastic seal.
Slightly experimenting, any home master with your own hands will connect the water supply system that will function as a clock.
Plastic structure water pipes This is a relatively new device. Combines the properties of metal and polymer pipes. Reminds pylted pie: polyethylene, glue, aluminum, glue, polyethylene. Performance features Excellent: at a pressure of 9.8 atmosphere, they withstand the temperature 95o. With short-term overheating to 130 °. Frost resistant, easily save the specified form, bent even with hands.
They are used in the transportation systems of liquids, gases, heating systems, air conditioning, for warm floors. Connection diagram is similar to polypropylene tubes. But since they are more susceptible to mechanical damage, the effects of UV rays, the laying is carried out inside special boxes, walls, floors.
For connection, special fittings are released:
Installation does not require expensive equipment, special Education. When assembling the water supply, do it yourself, know: the latter connection is inconvenient, it can be "packing" inside the floor or wall. The first two in special boxes, for access when an emergency occurrence.
Visual installation scheme with description The main problem that the home master is solved during installation new system Heating: Connecting to metal pipes Plastic. Industry answers:
Instructions for work is similar to the compound of polypropylene pipes.
In the houses of the old building in the bathroom, the toilet was used cast iron pipes. I want to replace them with a modern analogue. It will cope easily, the main thing will agree with the neighbors on the riser so that there are no cases. Establish:
Now you know how the layout is done, the installation of sewage systems, heating, water supply modern materials. And also that homemade Master All on the shoulder.
In the process of repairing sewage, there is a need to remove part of the elements of the water supply system. This requires separating PVC pipes without damaging the product. This material is quite fragile, so the dismantling operation is carried out without applying super passions.
The need to repair PVC pipes for external sewage systems occurs for a number of signs:
The fault locations of the discharge system indoors are located in the discharge pipes from plumbing devices to the main riser. The latter may be damaged. Outdoor, in private house-building, is an underground highway from the building to the accumulator ( village Yama, septicchik). For the arrangement of the outer drain, sewer pipes PVC (redhead) are used.
The discharge pipes from plumbing devices have a diameter of 32, 40 or 50 mm. Connections of sewage pipes are a joint of one end of the product in the other of the other. Sealing rubber rings and plumbing grease are used for sealing.
The following types of sewage products are used indoors:
Disassembly begins with the uncovering elements household devices- corrugated shoga, cuff. Disconnect the sewer items simple enough. It is necessary to give a disconnected part of rotational and progressive movements. That is, turning for several degrees in both directions, pull in the opposite direction from the main structure.
It is not required to make sharp movements - with a certain effort, the dismantled item smoothly moves off the place. This disks the entire inner design. It is necessary not to forget about the removal of fasteners, - clamps.
It is more difficult with the separation of the main riser collected from polymeric details. If compensators were installed in the project, the disassembly will not create special problems. But it should be remembered that the riser is a generalic property. Therefore, all actions with it are committed with permission from management company (Zhek, Hue, ZhReu, etc.). Otherwise, for the consequences that arose, the culprit is responsible, the owner of the premises, which has settled the self-consuming repairs.
It is necessary to comply with the rules when separating the vertical sewer:
The presence of the compensator eliminates the product to one or another side to 10 cm. It must be remembered that the vertical design has a certain mass. Therefore, it is required to consolidate.
The jacks are processed by machine oil. Making rotational and progressive movements, the part is removed from the overall design. The absence of a compensator forces to resort to radical methods, - cut the fan tube.
PVC plastic sewer pipes are processed by most of the plumbing tools:
Mechanized adaptation - Bulgarian, saber saw.
When working, you need to pay attention to the presence of a number of other elements of communications:
Connections of sewage pipes that served 10 years or more can "fuck", "increments" to each other. A number of recommendations may help in such cases;
Methods for separating the parts of PVC pipes used for the device of the outer highway, exactly the same. But it is necessary to determine the place of damage and perform earthworks.
How and what methods of turning pipes, - choose the owner of housing or invited professionals. The main thing is to determine the feasibility of this or that way of dismantling faulty parts.
The comfort of the tenants of the apartment or private house is impossible without a high-quality sewer system. Imported furniture and chic design in rooms do not have weights, if the waste pipes are suitable. Therefore, a literate installation of sewage is required before laying the water supply pVC pipes or cast iron structures. Consider the peculiarities of working with a plastic pipeline, since the tap communications are increasingly performed from PVC. We will tell about the work algorithm, sharing the secrets and chips of professionals.
In 99% of cases during the installation of sewage, plastic pipes (polypropylene, polyvinyl chloride, polyethylene) are used. The advantages of communications from synthetic materials are easily, ease of assembly, hydrothermal load and corrosion resistance, durability.
PVC products are most common when laying sewers
Note: Plastic parts can be used for sewage structures than a much less thickness than for water supply, as the pressure is below.
The diameter is the key factor to which you want to navigate. This value depends on the type of sanitary equipment. Minimum diameters:
Before taking the installation of sewage pipes with your own hands, make a detailed schema of the future system of communications with consumables calculations. Calculate the number and member of details and fittings.
Stools and fittings with fitting Process sealants for strength
The use of common flow for several plumbing devices will save money and place indoors, the result will be aesthetically. Select the desired pipe diameter based on the above recommendations - sink, bath, washing machine can be connected to one pipe that goes into a common riser. The toilet must be connected directly to the riser - separately.
Conduct dismantling of sewer pipes and laying new communications in a private house on time from day to several days, in the apartment - from 1-2 to several hours. An illiterate approach and the lack of plan will stretch out the event for weeks. Therefore, carefully prepare before starting work.
When laying a PVC product, apply the mark on the entire circumference
For cutting plastic parts, just like when installing cast-iron sewer pipes, use the metal hacksaw.
Cutting algorithm:
Consider that the waste system is installed under a slope, since the sewage system works on the basis of the force of attraction. Fix the slope using brackets on the walls. You need to buy them in advance with the rest of the materials.
To avoid leaks and inconsistencies, when assembling sewage, it is recommended to move in the direction from the riser to the plumbing instruments.
Creparate PVC communication to the wall every 100 cm, it will prevent snacks and breakdowns
Instructions for the installation of sewage from plastic pipes:
Tip: To increase the tightness of the master, they advise to lubricate the ends of segments with non-acidic sealants, soap solution, auto-heroleters or glycerol-based lubricants.
Try to reduce the number of joints and turns, one-piece communication is more reliable and more durable. Each bond is a potential threat of leaks in the future, turns increase the risk of clogging.
For a qualitative result, follow the rules for installing sewer pipes:
Despite the fact that in the event of a breakdown, it is easier to remove PVC pipes than to make dismantling of cast-iron sewer pipes, the event is troublesome and costs money. In order, in the case of a block, you did not have to tear or replace the installed communications, pride "cleanings" with plugs. Another preventive measure - additional vertical taps for air check valves (sufficient diameter of 50 mm).
To clean the possible blockages, leave a revision with a plug - it will simplify access to the driving area
Revisions with removable covers when mounting pipes for external sewage are installed every 15 m. For internal systems - At the junction of horizontal sites with a riser. This step will simplify the sewage cleaning if it breaks.
Upon completion of the work, spend tests of the sewer system for tightness.
Verification options:
During the check, learn all the joints and connections. If problems have not been detected, the test passed successfully. If there are leaks, secure and re-process problem areas with sealants or construction glue. After drying insulating substances, re-test the tests.
During tests, pay attention to the joints and attachments to fittings
Connecting a washing machine to sewage, in our time, quite simple and inexpensive. With the connection of the typewriter to the hydraulic sealer under the sink, any little bit homemade craftsman can cope, but it happens that the draining must be connected to the riser.
The easiest way to do it on the top floor apartment houseSince in this case, there is no need to negotiate with the tenants of the house. Otherwise, you will have to bypass all the tenants living above and ask them to not use the sewage during the work.
We will analyze the cutting of the drain in more detail on the example.
As a rule, the riser has a diameter of 110 mm. In the example below, the pipe diameter is 50 mm, it consists of two parts and is on the top floor. Therefore, when you will do your insert, you should consider the design features specifically your riser. This applies to diameter and possibly additional details, incospaid in the example.
