Most communications in multi-family housing on the secondary market are worn out. Replacement of sewage occurs for various reasons, but the work is carried out by the same scheme.
Each action is associated with the repair of communications, begins with an explanation of the causes of problems. It should be clarified that the replacement of old sewer pipes in the apartment can be total or partial.
Why do I need to repair communication
Partial replacement of sewage networks - eliminating end-of-discharge systems, in a single room. Such action is needed in the following cases:
- occurrence of leakage in the riser;
- overhaul of the sewage system owner and the tenant on their own;
- scheduled replacement of communications, due to the deterioration of their total.
In apartment buildings, built more than 10-20 years ago, communications were made from cast iron products. The material itself is considered to be very reliable, but it is severe with time, settles on the walls of the rust, so in need of repair.
Who is responsible for repairs
There are a number of normative documents regulating the rules of operation and repair of sewer drains in the apartment:
- Government Decree of 08.08.2006, № 491 "about the content of public property."
- Decree of the State Construction Committee of the technical standards of housing for operation from 27.09.2006 № 170
- Instructions for maintenance and repair of public property from 02.04.2004 year.
These documents confirm that the replacement of sewer risers in the apartment, all repairs and service activities are the responsibility of the management company of the building.
To carry out these works to the owner or tenant must provide a statement in the housing to replace the pipes with the specified cause breakage. After that, at the agreed time, housing landlord must provide access to all necessary communications.
Note! All statements regarding the company's employees of money to pay for the work, as well as a request to purchase the materials are not legitimate.
It is worth mentioning that the utility may refuse to repair, if you have outstanding monthly payments. The exception is an emergency situation, when, under the threat of flooding are other apartments. In this case, the repair team just put the cap on the challenge to your site riser.
If the specified place of residence have been conducted repair work, and you change the vertical pipe, then for having problems with self intervention tenants have to meet the owners and all the consequences, including compensation for damage to other owners will be your responsibility.
Replacement of sewage in toilet drain pipe may occur due to blockages. It is also the responsibility of the management company. Since the drain design runs throughout the home, and in the event of the reasons you can not install the culprit, public utilities are required to fix the problem yourself. Even if there was a blockage on the top floor, the owner can claim that the problem is connected with the roof, where there is access for all.
Since the waste of communication cost on the balance sheet of general building, planned repairs and replacement of old iron sewer pipes with plastic financed from the funds received in the capital home repairs. If the change of a working sewerage held on the initiative of the owner, then pay for all the work he will be alone.
Please note that all the work carried out without notice to the management company, it is removed from all responsibility.
Replacing the sewer own
If you decide to repair the sewer with your hands, consider the following:
- Be sure to notify the public utilities of all ongoing work that you intend to produce on their own.
- Inform neighbors about the time of the work in advance, and ask them not to use at this point drain. It is advisable to do it in person and explain the reason.
- It is impossible to carry out repairs, until the water supply to the riser will be disconnected.
Before starting the plumbing necessary to take care in advance of the availability of the required materials and tools. You will need:
- hammer bolgarka pipe thread, perforator;
- If the wire is replaced metal with plastic need a soldering iron to plastic;
- solution or a silicone sealant;
- fixing elements (clamps);
- plastic pipe bends, fittings, tees;
- elastics for sealing cuffs for additional sealing.
In addition to this level and prepare roulette for measuring distance and for applying marking pencil.
One of the important aspects of preparation is the selection of the right diameter fasteners. This setting directly affects the functioning of the sewage. Size corrugated siphon for mounting in the bathroom or under the sink is 3.2-5 cm., If there additional connection of the washing machine, the diameter is 2.5 cm, while for toilet cuffs 11-12.5 cm.
Scheme of work
Repairs begin with the dismantling of the old communications. The removal can be carried out in two ways:
- without affecting interfloor slabs;
- taking into account the space between the beams.
To disassemble the pipe itself in both cases the procedure is the same. The only difference in the opening overlaps. Phase of work will be as follows:
- At the level of 1 meter from the demountable part of the old parts incision grinder, removed old sewer pipe portion below the funnel.
- If the design does not lend itself to the elimination of the old sealant, try to heat it to soften the fixing material.
- structure analysis is carried out, starting from the top.
- If you want an autopsy interfloor slabs need permission neighbors. Need for dismantling the punch and a hammer. Work performed by the swing, without inflicting severe blows. Strong impact on the old cast iron risers can cause cracks or completely split pipe.
After dismantling the standpipe carefully removed tee. The last step is carried out by stripping pipe sticking dirt, removal of old grease from the socket.
How to assemble a new sewer system
Most often, the replacement takes place in the toilet, where the chief sanitary drain. The procedure for construction of the collection will be:
- It sets a new tee at the old place.
- Bottom rubber sleeve mounted previously lubricated with silicone sealant.
- The crossbar portion is placed desired pipe diameter.
- Riser clamps fixed to the wall with four different directions for safety.
Consider the point that modern pipe produce a lot of noise during the passage of the water, so it is better to take care of the sound insulation.
If you change the system of iron onto the polypropylene is required to do the following:
- Slices on the inside must be clean of burrs, as they will interfere with the work and become a source of waste collection.
- To facilitate the approach of elements to each other, face soap grease. This will improve the slip and will not allow damage to the pipe.
- Replacement is performed from below upwards towards the water flow.
With the help of measuring instruments approximate outlines new design laying plan, taking into account the slope of 5 degrees to the standpipe. This is necessary to maintain the pressure level. He should be above atmospheric pressure. After plumbing installed, using a rubber cuff.
Replacement of sewer system in a private home
Monitor the status of sanitary pipes in your own house must be very carefully. After the blockage or leak will lead to major problems for the hosts. When the time comes to replace old pipes, all work can be done independently, without waiting for the repair team.
Events for replacing sewer construction in a private home or in the country begin with the preparatory work, the selection of tools and material selection. Planning also includes charting, where the replacement will be carried out. The equipment you need to prepare in advance to check its serviceability. You will need: hammer, level, gun sealant, an adjustable wrench, a hammer.
Installation of new designs involves the removal of old systems. The algorithm of work is as follows:
- You must turn off the water around the house and drain excess fluid from the tank toilet and bath.
- Disconnected from the system plumbing devices (washing, sink, washing machine, etc.).
- Disconnect the pipes installed in the crosspiece.
- Spend socket cleaning, remove the old grease.
After all the preparatory work and the removal of the old structure, you can begin collecting the new sewer.
size 110 cm tube was inserted into the crossbar. In place of the junction with the bathroom need an adapter to a diameter of 50 cm. To a 110 cm tee joined pipe toilet. Compact further connected corrugated pipe joints are pre-lubricated with silicone.
Mounting corners by means of angles. To be able to connect to the sewer of new technology should be provided tees. Further mounted plumbing and reviewed all of spillways. For this draining is carried out for each hole of about 15 liters.
Installing sewers in suburban site
If you spend at the cottage only saving time and does not happen there is always a better option for the installation of sewers will trenchless method. In this technology, you can note a number of positive aspects:
- Modern equipment increases the reliability and lifetime of soldering pipes.
- The technology allows you to quickly perform all the work, while increasing the diameter of the pipe.
- No need for excavation.
Trenchless quick replacement of sewer pipes is carried out in several ways:
- Prokop road. Used for manufacturing small diameter.
- Punching case. This applies to the broad pipes (160-1450 cm).
- Horizontal drilling. The most common way for the construction of sewers with diameters ranging from 110 to 800 cm.
Preparatory work is required, but on their own to carry out this drains you can not. There will require specialists and technicians. They quickly eliminate the old communications, check the pump equipment, will conduct a study of soil.
Most owners use plastic products when replacing old guttering. They are best tolerate temperature fluctuations, are not affected by rust and are more than 70 years.
Professional advice when sewer replacement in a private house
Qualitative performance of work depends on the strict implementation of all requirements. To avoid problems in the future should heed the advice of professionals.
First, before starting work on the replacement or arrangement of the new sewage system in a private home, determine the type of soil, which will lay a pipeline. It is also worth considering the presence of the cesspool, septic tank or other device.
Secondly, for outdoor applications, use PVC products, the selection of the diameter depends on the number of plumbing fixtures and pump power.
Third, for the laying of pipes in the ground be sure of their insulation. To do this, you can use different insulation (foam, mineral wool, etc.), as well as carried out the heating cable.
On straight stretches, always observe the slope of 3 degrees to avoid any stagnation. The rotation angle of the internal wiring does not exceed 45 degrees.
In the end it is worth noting that the installation and repair of sewer depends on many factors, and will be different technologies, depending on where you live.
