Need to replace the valve on the riser. Who should carry out this business? Who pays for it? If this private house, then such questions do not arise. WITH apartment buildings It is not that simple.
In practice, it turns out differently. In the best case, after contacting, they can offer to buy a faucet. This is at its best. Most often, the management company asks to pay for disconnecting the riser, the plumber for the work. This is a “money scam”. It is illegal.
We pay for maintenance every month management company... Therefore, they are obliged to replace the valve on the riser at their own expense. And get the valve, and do the work.
If the faucet on the riser is leaking, and the plumbers and their bosses shrug their shoulders and look into your wallet, go for it.
1. Write two copies of the application. On your request to put a note of receipt, date. State the problem in detail in your application (samples should be offered).
2. If there is no response, write a complaint to the higher authorities (GZI, district administration).
Do not forget to notify the head of the management company about point 2 in advance. You may not have to complain anywhere.
This is a direct way to get what you want. The most thorny and nervous. There are also roundabouts. For example,
1. Disconnect the bathroom or kitchen faucet and call emergency services. Tell them that you cannot turn off the water. the valve on the riser is not working. Within half an hour or an hour, the problem will be fixed.
2. Call the private organization, which will do all the work without noise and dust for an additional fee.
3. Replace the riser valve yourself.
Which crane to put on the riser? You can purchase an old-style valve, or you can install a ball valve.
1. In conventional stem taps, an elastic band is screwed at the bottom. The rod presses it down, so that the water is shut off.
2. Ball valve on a riser looks more attractive than a stock.
The water is covered by a ball-sphere. But if the water contains a lot of salts, then the tap quickly clogs up and stops working. To prevent this from happening, periodically you need to twist and unscrew the valve.
Rules for choosing a ball valve:
Types of threads on valve flanges:
Work order:
1. Cut off the water supply of the riser, drain the water from the pipeline system (in agreement with the management company).
2. Wrap fum tape or tape with a sealing agent on the tap threads. You need to reel in the direction of winding the crane onto the pipe.
3. Screw the product onto the pipe. If the twisting goes without effort, you need to add more fum tapes. You should not lean too much, because the product will burst. The tap should be twisted with some effort.
This should never be practiced.
Work order:
1. Prepare buckets, a bunch of rags and invite an assistant.
2. Purchase a new cock, seal its thread and open it.
3. Unscrew the inoperative tap.
4. Pass the water through the new tap.
5. Tighten it approximately two turns. Now you can turn off the new tap and screw it on completely.
To minimize the flow of water, you can put a hose on the new faucet and lower one end of it into a large basin. It is recommended to undertake such work only for people who are confident in their abilities and physical strength... Water pressure can be serious. We need to prepare for this.
Often it becomes necessary, instead of the old tap, which has ceased to hold water, to cut a new tap into the water riser. It seems that there should not be any problems: you twist or cut off your old fittings with the help of a grinder, electric or gas welding, and in its place you screw or weld a new analogue.
Yes, this will be so if it is possible to turn off the water using another tap or valve. But most often they are not there, and if they are, then they have long been out of order and do not perform their direct functions, that is, they do not hold water. Sometimes, as a result of numerous building reconstructions, alterations or redevelopments, perhaps even the place of their location has been forgotten or it turned out to be completely inaccessible.
It seems that the situation is hopeless. However, do not despair. Now we will try with the help of simple and quite affordable tools and materials to carry out our plans and, nevertheless, install a new product instead of the old crane.
Materials and tools used
For this work, we need the following tools and materials:
Pipe sealing tool
It is probably necessary to briefly describe the construction of the water shut-off device and its operation. It is a hairpin, at one end of which a valve made of elastic material is fixed - a piece of rubber hose, on the other - a nut is screwed on. And between them is a piece of pipe, where the hairpin freely enters. The length of the pipe should be shorter than the section of the stud from the valve to approximately the middle of the thread, so that after installing the device in the right place, tighten the nut on the stud and, thereby, compress the elastic valve, sealing the annular gap between it and the inner wall of the riser outlet pipe. 
Pressure valve replacement process
Since it was not possible to turn off the water, it is barely restrained under pressure by the old tap, which at any moment can give even more leakage. It is necessary to act very quickly and very desirable together. 
It is necessary, as quickly as possible, by means of an adjustable wrench, to unscrew the used tap and insert, overcoming the pressure of water, into the outlet a sealing device to the required depth. 
He unscrewed the tap, the pressure rushed. 
We insert the device. 
Then, holding it in the pipe, using a wrench, tighten the nut on the rod of the fixture until water stops flowing from the gap between the steel ridge and the fixture. 
Now you can, without fear of leaks, cut off part of the bend using a grinder. Moreover, the place of the cut must be marked without reaching the section where the valve of the device seals the outlet of the riser. After complete separation, the piece of pipe should be removed carefully, without strongly affecting the device. 
To imagine how the new crane will be located on the pipe, you can try it on in place, placing the lamb on top, side or bottom, to determine the most convenient position during operation. 
The next stage is very important: it is necessary to weld a squeegee to the branch using electric welding, onto which we will later screw a new crane. Before the beginning welding works for the reliability of the connection at the end of the cut pipe, you can make a small chamfer using a metal file. It is usually already available on squeegees. This will allow the welded seam to fit well into the formed recess and ensure the quality, tightness and reliability of the connection. 
After the squeegee has cooled down, several layers of FUM tape should be wound on its thread in the direction of screwing, i.e. clockwise. This will increase the tightness of the new crane on the sled and the tightness of the connection. You need to screw the tap with one hand, slowly and carefully, especially at the beginning, so as to get into the thread and not accidentally rip it off. At the very end, you can make a tightening with a key, but at a small angle. 
After the final installation of the new valve, it is time to unscrew the sealing device. It is necessary to loosen the nut with a wrench and slightly push the rod towards the riser in order to release the elastic element in the longitudinal direction, which will allow it to lengthen, and at the same time decrease by cross section... Now, without delay, we take out the device, shaking it from side to side, and quickly close the new valve. The work has been successfully completed. 
Conclusion
The pipe sealing device should be checked before use, especially if it has not been used for a long time. The elastic element acting as a valve should not have cracks and gaps. The thread on the rod must be cleaned of dust, dirt, rust and lubricated with some kind of oil. Then thread the nut from end to end several times.
To seal the thread between the squeegee and the tap, instead of FUM tape, it is preferable to use a universal nylon cord impregnated with a special sealing compound. It is more reliable, it is not afraid of cold and heat, it is not weakened by vibration. 
In this way, it is not recommended to change the valve on the riser with hot water... And in general, if you have at least some opportunity to block the riser, then you should use it, and this method should be used only as a last resort.

Leakage of valves on the riser is not uncommon in an apartment. Over time, the pipes wear out, which inevitably leads to water leakage. Replacing the taps on the riser should be carried out by specialists, only then the result will be satisfactory. Independent attempts can lead to an emergency.... In this case, the price of replacing ball valves can rise many times over. The craftsmen know about all the intricacies of the work, so it is better not to save money, but immediately contact the professionals.
Before proceeding, the specialist assesses the situation. Replacing a ball valve on a riser requires a professional approach. The specialists of the StroyGarantia company have all the necessary skills and easily determine the nuances that ordinary tenants do not even know about. This includes:
The first problem faced by the apartment owner is the need to shut off the water in the riser. You can't do it on your own - you need to contact the utilities or the management company... The pipes can be closed only during a certain period of time. This can only be done on weekdays from 10 am to 1 pm If the repair of the crane is delayed, this will cause discontent among the neighbors.
Products are copper, brass, cast iron - each of these materials requires proper handling during installation and dismantling. Otherwise, unforeseen complications are possible: you can break the thread, break the integrity of the gasket, and so on.
Our craftsmen with 20 years of experience are familiar with the peculiarities of crane installation firsthand and will be able to quickly take emergency measures in case of an emergency.
Only theoretical knowledge of the procedure for performing the work will not help to replace the valve on the risers. In most cases, such attempts have to pay double the price later. Often, after self-intervention, additional costs for materials may be required.
We practice the simplest, fastest and most effective method replacement and dismantling of ball valves on the riser. At the same time, the price for the service remains unchanged! An employee of the company uses a special device that allows you to freeze the desired section of the pipe. This approach becomes the most effective for residents of apartment buildings.
The failed mechanism is unscrewed. If necessary (for example, in case of damage to the thread by corrosion), the damaged part of the pipe is cut off. The edges are sanded and a new ball valve is inserted. A fum tape is wound on the thread, the twisting procedure is performed carefully and carefully (you cannot exert too much effort, otherwise the product will burst).
After installing a new locking mechanism the system must be checked for leaks... If necessary, the disadvantages are eliminated. Each stage of the repair is carried out at a high professional level... Turning to us for a crane replacement service, you can be sure of the quality of service and an adequate price.
The cost of repairs is formed based on the number of services provided and the price Supplies... All work is fixed on the spot, an individual estimate is drawn up. When buying plumbing equipment, the master provides receipts. This is done during any work, be it installation false ceilings etc.
In this sequence, professional replacement of riser valves is performed. The price of the work is quite affordable for Moscow residents. However, the main thing we are aiming at is high quality services. At the end of the process, an act of work performed in the apartment is drawn up. Everything is fair and transparent. We value our reputation.
During repair work, it may sometimes be necessary to shut off the water in the apartment. Can this be done so that all residents of the entrance do not suffer from dehydration? Let's consider the main methods.
This can be done in a separate apartment only if there are special valves in the bathroom. But this method is appropriate only when it is planned to carry out minor work. For example, repair a crane. If you plan to install plumbing in the toilet / bathroom or other labor-intensive work, you need to shut off the water along the entire length of the riser. This design is a pipeline. The stand is intended for 1-2 apartments.
If there is a valve in the bathroom, turn it clockwise to the end. What if the apartment is old and there is no valve in it? In this case, you will inevitably have to contact a specialist from the housing office. The locksmith will not be able to turn off the water in a single apartment, only in the entire entrance.
In the event that the main pipe has broken through, the overlap is made throughout the house. This work can even affect several buildings.
Bathtub and toilet pipes in new buildings usually have valves. Through them, you can easily turn off the water in a separate apartment. In other cases, there is even a special sensor on the pipes that automatically detects problems and turns off the structure.
The riser is usually located in the toilet or kitchen. Its main purpose is water supply. It is possible to overlap in it only if there are valves on the structure. If they are not there, you need to think about installing the elements. The best choice in this case, ball valves will become.
If old elements with defects are installed on the pipeline, it is better to think about replacing them, because in the event of an emergency they can fail, and you will flood your neighbors. It is better to entrust their installation to a specialist. The plumber will be able to determine what diameter of the product is required for your particular riser.
After installing the valves, one should not forget about the importance of preventive maintenance. It is recommended to shut off the risers once every three months, and then turn them on again. This is necessary so that the elements do not stagnate, they do a good job with all their functions. It is better to prevent their breakdown, because in an extreme situation the valves can fail, and you cannot do anything about it. If any problems arise, it is better to call the foreman who will check the condition of the valves and carry out the necessary repairs.
In conclusion, we can say that shutting off the water is easy only if a person has taken care of this in advance. If the valves have not been installed, it is almost impossible to disconnect in one apartment. For this reason, it is better to anticipate the occurrence of further problems and establish them, because shutdown may be required not only during repair work, but also in case of emergencies.
In this article, we will tell you how to shut off the water supply pipes in an apartment. Why this is done is understandable, in order to completely shut off cold or hot water coming to us from outside. There are situations when, for example, a tap has leaked and the gasket needs to be replaced, or we bought a new mixer and want to install it to replace the old one.
If you do not know, in principle, how to turn off the water in the apartment, be sure to read the article to the end. So, water comes to our apartment through plumbing pipes. Risers are long pipes that usually run from floor to ceiling. If you live on the top floor, the configuration may be different. In many apartments such as "Khrushchev" and "Brezhnevka" risers run in the toilet. However, in some old houses, in addition to the toilet, they can also be found in the kitchen.
The main purpose of the risers is to supply hot and cold water to the apartment. If the house does not have a gas water heater, then, as a rule, you have 2 risers: for cold and hot water. If the house has a gas water heater, then there is only one riser - with cold water.
For safety reasons, it is very important that there are reliable valves at the entrance to the apartment with which you could easily turn off the water at any time and turn it on again.
Ball valves are the best choice in this case. On pipes, they look like this:
Their reliability has been tested by time. Apartments usually use 1/2 ", 3/4", 1 "ball valves. It so happened that they are measured not in millimeters, but in inches. Hence the conversations of the plumbers: "I gave you half an inch." Or "Let's put it on three-quarters."
If, instead of ball valves, you have something unclear: something very old, difficult to turn by hand or, even worse, leaking, my advice to you is to change it urgently! When water suddenly pours out of these taps, it will be a disaster! After all, there will be nothing to stop this water! You will flood yourself and all the neighbors below. Don't think that emergency service She will save you, she simply will not have time. If the fountain comes on, then in half an hour you will flood the whole house and get rid of problems for life! Therefore, in a new apartment, before you are going to glue the wallpaper, level the walls, whitewash the ceilings, check the inlet water valves and put in good, proven ones.
Entrust the installation of ball valves to a plumber. But first, read my article so that a professional really comes to you. What diameter to install the crane is a very individual topic, the master himself will advise you. But you must insist that the apartment has a good pressure of water, both hot and cold. Also tell the master to put only high-quality parts!
I will tell you a secret that a real professional will appreciate your requirements, although he will warn you that it will be more expensive. The fact is that it is much more convenient for the master himself to work with high-quality material, since the reliability of his work increases significantly. Both you and him will be much calmer that you have taken this topic seriously.
And now, a few words of advice. When you have installed ball valves and turned on the water, do not forget to turn off the risers every 3 months, and then turn on, that is, just close each of the taps:
and then reopen:
It is important that the valves do not stagnate in one position! You need to periodically monitor how they open and close. If you feel that something is wrong, call the master. Ball valves on risers are bad jokes, as well as electricity!
So, today we have learned how to shut off the risers of water supply in an apartment for cold and hot water and what you need to pay attention to when choosing and replacing taps. I wonder how often did you change the ball valves in your apartment?
Lesson 7. How to shut off the water supply pipes in the apartment
Is it possible to replace the stopcock without shutting off the water.
Do not practice on upper floors!
Do not do this with hot water and heating!
One of the readers of the site under the nickname, stefano asked a similar question:
Tell me how to proceed. The house has a riser and water outlets made of polypropylene pipes. A crane flew on one of the bends. Can you somehow replace it without shutting off the water throughout the house? And what is better to put? We cut off the water every day before leaving for work.
The first thing to do is to fix the pipes on which the meters are hanging. There should be no meters hanging on the pipes.
To replace the taps, you will have to turn off the riser. You can, of course, install a duplicate if this one is also overlapped, but this is only in a very extreme case.
In your case, it is better to turn off the riser. If this is possible, then after disconnecting, you will have to re-solder something here, namely: if you look at the photo, then after the meters you have two 90-degree bends installed, which lead the pipe closer to the wall. With the same two taps, take the faucet and meters to the wall immediately after the riser. Further, the meters must be put on clamps so that they do not hang on the pipes.
For example, use the following clamps:
They fit very well into the girth of the half-sleeves of the counters. Almost invisible after installation.
As for the shut-off valves, then install reinforced Valtek taps, or for example Bugatti. 
There is material about shut-off valves here and there.
If it is impossible to turn off the water at all and there is no apparatus for freezing pipes
Then you have to be ready for water.
If you decide to change or install duplicate taps without interrupting the water, then the floor below should not have rooms that can be flooded. Even if you are on the first floor, this does not guarantee that there are no rooms below. The basement may contain warehouses or commercial premises.
If you are going to do this in a basement or in a private house, then go ahead.
Find a large container or stock up on a pile of water-absorbing material. For example, a lot of expensive and high quality towels. If possible, place a large container in front of the faucet.
Look for an assistant who is not averse to pouring cold water on it. You hand him a large rag or all the same expensive towel and let him catch all the water coming from the tap into this towel, like a motorized bull.
You need to prepare in advance the replacement valve, seal its threads and open it. Then unscrew the non-working faucet or what is after the faucet if you install a redundant one. Now you can screw in a new one.
As an example, I enclose several images made "in greenhouse conditions". All threads in the photo are not sealed because this is a simple example.
Here we have a threaded pipe or an old non-overlapping faucet, water flows from it.
We take a new faucet and open it completely. We seal the thread and pass water through it.
Tighten about 2 turns, after which the tap can be closed and tightened by the remaining 1 or 2 turns.
You can also screw a flexible hose or hose onto the new tap and lower the other end of the hose into a bucket or bathroom into the nasalization. Most of the water will go out through the hose. But something will still spill on the floor.
Anyone who undertakes this must understand the full responsibility of actions, must be confident in what he is doing and must be physically strong.
The pressure can be quite high and you need to be prepared for this. It's better to know beforehand what kind of pressure you are dealing with.
Would come in handy:
1. Hose
2. Large capacity
3. Assistant.
4. Rags

Even the highest quality plumbing breaks down after a while. However, not everyone is able to independently solve the problem and fix a leaking tap. Do not postpone repairs for a long time. After all, a leak increases water consumption, spoils appearance plumbing with ugly smudges and traces of rust. You can fix the faucet yourself. What is required for this and how to carry out the repair?
If the tap is leaking, you can fix it yourself. First you need to prepare everything. If the packaging from the mixer has been preserved, then it is worth finding it. As a rule, it will contain detailed instructions describing the structure of the accessory and some recommendations for its repair. In addition, the package may contain tools needed to repair the crane.
Before starting repairs, turn off the water. To do this, close the valve. In this case, it is necessary to turn off the supply of not only cold, but also hot water. You will need a deep container, such as a bowl, to collect the liquid. Have dry cloths or sponges handy during repairs to wipe away splashes.
After preparatory work you can start troubleshooting the mixer. If a closed tap is leaking, then special tools will be required to repair it. They need to be prepared in advance. To troubleshoot you will need:
This simple set of tools is usually enough to fix a leak. If there is no time to run after new pads, then they can be made of leather or rubber. Typically, the valve leaks due to wear on this part. A soft material is required to protect the sink from damage. After all, the tool can slip out of your hands. As a result, ceramic products may break, and enamel will crack on metal ones.
Why is the tap leaking? Most often, these accessories wear out the liner or gasket. To replace it, you need:
If the valve has been leaking for a long time and a quick replacement is required, then a new gasket can be purchased from a specialized store. This will save time. As for the homemade part, it is more suitable for short-term repair of a breakdown.
The two-valve valve leaks for several reasons: a worn-out gasket or wear of the gland seal insert. If necessary, both parts can be replaced by yourself. Wearing the gland liner can be recognized by the flowing water between the valve stem and the gland nut. To fix a breakdown, you must:
If everything is done correctly, the flow will stop. This will make the valve turn more smoothly.
Often, a leak appears in the place where the shower hose and mixer are connected. The main reason for this failure is the wear of the O-ring. This part can be easily replaced. For this it is worth:
To eliminate such a leak, experts recommend using a silicone O-ring. Parts made of rubber are short-lived and wear out quickly.
If, when switching the water flow to the shower hose, everything flows smoothly, then the shut-off element must be replaced. This part is called "axle-box crane". The shut-off element is located in the mixer handle. You can buy a crane box in a specialized store.
If the tap is leaking, then it is necessary to fix the problem quickly and efficiently. Otherwise, water can cause more destruction and permanently ruin the plumbing. Single-lever ball-type products may become unusable:
A defect on the body can be repaired by applying cold welding or sealant. However, this is only a temporary measure. After some time, a complete replacement of the structure will be required.
If the reason lies in a rusted aerator, then it should be removed and then cleaned. This can be done with an old toothbrush. It is worth noting that after cleaning, the water pressure will become stronger.
The ball valve has more complex structure and differs from the two-valve. Most often, such products break down due to dirt accumulated inside the case. It is she who disrupts the operation of the mixer. If water flows from the tap, then it must be disassembled, well cleaned and reassembled. This requires:
What to do if the tap is leaking? How to fix a new mixer? As a rule, such products cannot be repaired. The main reason for their occurrence is a factory defect. For troubleshooting, dismantle the new mixer and take it back to the store. You are obliged to replace the damaged product. The main thing is not to throw away the receipt and documents before the first sample of the mixer. Only a professional plumber can repair a crane that has a factory defect at home.
If desired, the mixer in the bath or in the kitchen can be repaired by yourself. This will save you a decent amount. However, repairs do not always allow you to fully restore the functions of the crane. In most cases, a complete frequent breakdowns, you should carefully consider the choice of accessory. Consider:
A running tap in a bathroom or kitchen is unpleasant. Constantly dripping water irritates and spoils the appearance of the plumbing. You can fix the problem yourself. The main thing is to clearly imagine the structure of the structure and have it at hand necessary tools... The repair of the product also depends on its type. Most often, ball and two-valve mixers fail.
