Is it possible to open and close the inlet water tap in the apartment every day

Heating radiator piping with bypass

Having decided why a bypass is needed in the heating system, you can begin installation work. At the same time, calculations are made, as well as components are selected. The material of the pipes should ideally match the material of the main line.The diameter of the regulator must be smaller than the cross section of the main pipeline.

Strapping options for different systems

Some tips to help you install:

• ball valves are suitable for shut-off valves. They allow you to reliably shut off the supply of coolant;
• you should not install a mixing valve, which will not be useful in normal wiring;
• installation of a regulating mechanism for single-pipe systems is considered necessary.

The diagram shows the constituent elements of the structure

Before installation, the distance between the return and direct lines of the battery is measured. Then a piece of pipe of the desired size is cut off. This piece, in turn, is also cut in half and a ball valve is installed in it. In the case of using polypropylene pipes, pressure testing is carried out using a hydraulic method. Tees cut into the supply and return branches and a prepared jumper is installed. To be able to replace radiators without draining the entire system, ball valves are also mounted at the inlet and outlet of the device. Then the pipes are filled with coolant.

The nuances of installing a control device are shown in the diagram

The principle of operation of the bypass on the radiator

In a single-pipe design, the installation of a bypass for heating is necessary so that when the heating device is replaced, the liquid continues to circulate. In a vertical installation, the radiator is connected to the riser by pipes. The regulator combines pipes and is mounted in front of the battery.

The diagram shows the installation location of the bypass jumper on the entire heating system when using a solid fuel boiler

The functions of the jumper, which is placed in front of the radiator, include:

• creation of constant movement along the main contour;
• regulation of temperature and coolant flow directly in the radiator.

Installing a bypass allows you to mix the coolant from the central line with the return line of the battery. Due to this, the temperature and heating efficiency as a whole increase.

Strapping nuances

It is important to understand what a bypass is in a heating system before installing it. Here are some helpful tips to help you do your own installation:

• in order to direct the water in the right direction, it is necessary that the cross section of the jumper be smaller than the cross section of the main pipeline;
• installation of the structure is carried out next to the heating device, but as far as possible from the riser;
• taps are mounted between the input / output of the battery and the control jumper;
• thermostats are used to automate the temperature of the device;
• when installing the structure next to the boiler, overheating should not be allowed;
• tees are mounted on sections of the highway;
• do not install a valve or valve on a valveless device.

Piping option for single pipe construction

When installing the unit, the building regulations must be observed. Fasteners or special pipe supports must be present near the bypass device.

Repair of a single-lever faucet with a swivel spout

Faucets with a swivel spout are installed on sinks in the kitchen or bathroom. From time to time, a leak starts from under it. The locking mechanism in this case is not to blame, just the gaskets have lost their elasticity or the lubricant has dried up.

Repair of a single-lever mixer with a movable spout

In this case, disassemble the mixer as described above, then remove it by pulling up the spout. Remove all old gaskets.If they are stuck, you can use a flathead screwdriver or even a knife blade. You need to remove them, but they still need to be replaced. On the removed gaskets, select new ones. It is desirable that they be made of silicone, not rubber. Silicone is more elastic, retains its properties longer, better tolerates contact with water.

Lubricate new gaskets with sanitary silicone grease, install in place. Install the spout in place. It must be pressed down well so that it rests against the union nut on the mixer body. Next is the assembly of the rest of the mechanism.

Types of ball valves

Cranes differ from each other primarily in their purpose. Some of them can be used for cold water, others for hot water. The purpose of cranes determines their design features. Some models of cranes are collapsible, others are detachable. PP cranes with a detachable design are mounted where the question of disconnecting it from the network may arise. By the way, the connector can be installed on one or both sides of the valve body.

When connecting a collapsible faucet, union nuts are used. They are installed in systems where fittings made of metal are used, in steel pipelines and next to heating radiators.

Collapsible propylene taps have two designs - straight and angled. If everything is clear with straight taps, then the advantage of corner taps is that they are connected to the main line directly, without the help of auxiliary couplings. This design not only facilitates installation, but also increases the maintainability of the product. Thanks to the design of the valve, it can be quickly disassembled and repaired.

Manufacturers produce valves of different colors.Moreover, at the manufacturing stage, a color marking is applied to the body, which can tell what this or that crane is intended for. For example, a blue stripe indicates that this product is designed to operate in a cold environment.

Possible malfunctions and ways to eliminate them

The device needs to be repaired if:

1. the valve does not shut off the water. The causes of the malfunction may be:
   • wear of the sealing gasket serving as a locking device;
   • disconnection of the shut-off valve from the spindle;
   • spindle kink;
   • contamination of the valve with deposits contained in the water;

When bending the spindle or disconnecting the valve, crane box replacement.

1. leaking or dripping valve. The main reasons for such a malfunction can be:
   • the formation of a crack on the body of the device;
   • absence or insufficient amount of gland packing.

Replacing the gasket and cleaning the case

To repair the valve with your own hands when the gasket is worn, you will need the following tools and materials:

• wrench;
• a piece of plumbing rubber;
• scissors;
• pliers;
• knife;
• linen thread or other sealing material.

Rubber and scissors are required for self-manufacturing of the gasket. If you know which gasket is installed on the spindle, then you can purchase the finished product at a plumbing store.

The gasket is replaced as follows:

1. using an adjustable wrench, it is necessary to unscrew the crane box that fixes the valve spindle;

Valve disassembly for gasket replacement

1. pliers unscrew the nut that fixes the gasket;
2. the washer and the failed gasket are removed;
3. a piece of rubber is cut out, the dimensions of which are slightly larger than the dimensions of the valve;
4. a hole is made in the center of the cut piece of rubber;
5. rubber is mounted on the valve and fixed with a nut;
6. excess rubber is cut off with scissors around the valve. The finished gasket must fully match the dimensions of the valve;

Attaching a new gasket to the spindle

1. using a knife, the valve body is cleaned. It is recommended to carefully remove all deposits not only in the device case, but also in the threaded connection;

If it is not possible to clean the case by mechanical action, then kerosene or WD-40 liquid can be used.

1. the crane box is mounted on the thread;
2. the connection is sealed, after which the device can be completely fixed.

Thread sealing with linen thread

Repair of the valve must be carried out when the water supply (heating) is shut off.

Replacement of gland packing

If the faucet valve is leaking, then in most cases the problem is the absence or excessive sealing of the gland packing. For repairs you will need:

• an adjustable wrench or wrench of the appropriate size;
• gland packing;
• knife or flathead screwdriver for sealing.

In this situation, you can repair the valve yourself according to the following scheme:

1. shut off the water supply of the system;
2. remove the rotation handle;
3. unscrew the fixing nut. When loosening the fixation, it is recommended to hold the spindle in one position;
4. remove the sealing ring that secures the packing;
5. use a knife or screwdriver to remove the old packing;

The process of replacing the gland packing to eliminate the leak

1. apply and tamp down new sealing material;
2. assemble the faucet in reverse order.

The process of replacing the gasket and gland packing is described in detail in the video.

Crack repair

If the valve is leaking and the cause of the leak is a crack on the valve body, then you can:

• completely replace the valve;
• close the crack with special materials.

Crack in valve body

Among the materials used to seal cracks, one can distinguish a means for cold welding.

Means for cold metal welding

Detailed instructions for using the product are indicated on the package. The general usage pattern is as follows:

1. the place where the crack needs to be repaired is cleaned of dirt and degreased with acetone;
2. the composition is prepared for application;
3. the finished mixture is applied to the crack and evenly distributed over the surface;

For welding strength, it is recommended to apply the mixture to a larger area than the crack itself occupies.

1. complete drying of the composition is expected, after which it is possible to clean and paint the welding site.

The method of using cold welding to repair a crack

Thus, you can eliminate the most common valve problems yourself. If the repair work carried out did not help to correct the situation, then the valve must be replaced.

Troubleshooting a Worn Gasket Problem

This is the most common cause of failures in worm gear boxes. In addition, there are rubber gaskets in ceramic axle boxes, they are used both as goose seals and in flexible liner washers. The contact of the gasket with metal parts in the aquatic environment, the pressure on it of the parts of the mechanism and the possible drying out, in some cases, lead to deformation of the gasket.Due to rubber wear, water leaks from the tap or its buzz begins.

When water drips from a faucet, what do you need to do to replace the gasket:

• block the flow of water to the apartment;
• using a screwdriver and a flat knife, disassemble the mixer and remove the damaged gasket;
• change the gasket to a new product, it is better to use the factory options, although you can make the gasket yourself from suitable rubber;
• to assemble the mixer;
• check the operation of the crane.

Main causes of malfunctions

Bathroom faucet

A mixer is a device designed to control the temperature and flow of water from a tap. Products used in bathrooms have the function of redistributing the flow of water from the tap to the shower.

Self-repair of a faucet in the bathroom is greatly simplified if the cause of the breakdown is correctly determined:

• Low quality products. This is a problematic moment for goods from Turkey and China. Among them are not uncommon - fakes.
• The degree of purity of tap water is of decisive importance.
• Use of materials that do not match the quality of the device. For example, modern mixers are equipped with silicone or ceramic gaskets - the market is replete with similar rubber products (they are cheaper, their reliability is lower).
• Hard water leads to cracking of the parts of the mechanism, the formation of harmful deposits in the internal cavities.
• Natural wear of parts - sensors, cartridges, etc.

At the same time, it is important to know how to disassemble the faucet in the bathroom with a shower and what malfunctions cause such a need. Improper dismantling and installation of the product reduces its service life.

Here the type of mixer design plays a decisive role:

• single lever;
• double valve;
• sensory.

Each has specifics in the event of breakdowns, especially during disassembly and assembly. Next, we will determine what breakdowns are typical for each type of mixer, self-repair methodshow to disassemble the faucet in the bathroom according to a detailed algorithm.

Which ball valve is better to choose so that it works for a long time and reliably

Ball valves have long been widely used in pipeline systems, due to the simplicity of the device and ease of use. However, they must have another valuable quality: reliability. After all, if the crane is made of insufficient quality materials, it can fail prematurely, or even cause an accident. It is not uncommon for buyers, when deciding the question: “which valve to choose?”, In pursuit of savings, purchase ball valves made of cheap aluminum-based alloys, made by some unknown company. And this can turn into big troubles and losses - for example, if the tap breaks under the pressure of water, and the apartment of the neighbors below is flooded.

Option four. We change the cartridge

As noted earlier, it is much more convenient to use cartridges than crane boxes, but if the former fail, then need to be replaced immediately mechanism. The sequence of actions is given below.

Step 1
. First, unscrew the plug on the lever, and then unscrew the fixing screw itself.

Step 2
. Remove the decorative elements, then unscrew the nut holding the cartridge.

Step 3
. Remove the mechanism, look at the condition of the gaskets on its end. You can try replacing them.

Step 4
. If the seals cannot be replaced, install a new disc element in the valve.

Step 5
. Assemble all elements of the mixer back.

The need for shutdown

Before moving on to the scheme for disconnecting the battery from the riser in an apartment building, we suggest considering the basic reasons that can cause a malfunction in the heating system.

Here is a list of the most likely causes of battery failure:

• an emergency that threatens to flood your and your neighbor's apartment with a hot coolant;
• painting radiators in the cold season, when the heating is already on;
• if there is a need to change the radiator, or flush it;
• in winter the batteries are too hot and you want to lower the room temperature.

In some apartments, residents practice shutting off batteries in the summer without draining the coolant in order to protect radiators from blockages during the autumn heating system. At this time, the water through the pipes often comes with fragments of rust. How to do it correctly, we will tell in one of the sections of this article.

Opening and closing valves

It is possible to determine whether the valve is open or closed by several signs, depending on the type of device installed.

Determining the position of the ball valve

To determine the status of a ball valve, you can use:

1. control knob;
2. recess located on the stem.

The ball valve can be equipped with two types of handles:

• a handle, which is an elongated element attached to the body of the device;
• a butterfly handle consisting of two similar parts arranged symmetrically with respect to the attachment point.

The valve closes if the handle is turned perpendicular to the device and the direction of the pipeline, and opens if the handle is turned in the direction of the axis of the device and, accordingly, the pipeline.

Determination of the state of the valve by the handle installed on the device

The following video will help determine the state of the valve by the handle.

If the handles are broken or completely missing for some reason, is it possible to find out the position of the valve? To determine the condition of the device under the circumstances under consideration, you can use the groove located on the stem.

Element by which the position of the valve can be determined

If the groove is parallel to the pipeline, then the valve is open and passes liquid (gas). If the recess is located perpendicular to the direction of the pipes, then the valve is closed and the movement of fluid through the system is impossible.

Determining the position of the valve by recess

For ease of use of the ball valve, special protrusions are located on the body of the device, which are designed to limit the rotation of the handle and, as a result, extend the period of use of the device.

Determining the position of a plug valve

In which direction should the plug valve be unscrewed if there is no handle on the device, and how to find out the position of the valve in this case?

To determine the position of a valve that does not have a handle, you must:

1. find a slot on the top of the stem (risk);
2. visually check the status of the device.

Determination of the state of the plug valve in the absence of a handle

To close a valve of any type, it is necessary to turn the control handle or the mounting stem in a clockwise direction.To open the valve, the handle rotates in the opposite direction, that is, counterclockwise.

How to close the battery

To perform some work, it is only necessary to turn off the radiator:

If shut-off valves are installed - ball valves. it is simple to do this: you need to turn the cock handle to the stop on the supply and return pipes. The coolant flow is blocked, the heater can be removed.

If there are ball valves in front of the radiator, they are closed and the radiator is removed

Sometimes a manual control valve is installed on the supply. It can also shut off the supply of coolant, but its main function is to regulate: it is installed to maintain a constant temperature in the room.

If the heating season is over, by closing the taps, you can safely remove the radiator. If there is a need to perform work during the heating period, it is necessary to take into account the peculiarity of the installation. In a single-pipe system with vertical wiring, shutdown without shutting down the system is only possible if a bypass is present.

A single-pipe system with vertical wiring looks like this: coming out of the ceiling one pipe enters the radiator, the second exits from another hole in the battery and goes to the floor.

The bypass is a jumper in front of the radiator. It connects the supply and return pipes. It is performed, as a rule, with a pipe size one step smaller than the diameter of the liner.

If there is a bypass, then when the radiator is turned off, the coolant continues to circulate through the riser, but already goes through this jumper. As a result, no one suffers: the neighbors are warm, you carry out the required work.

Bypass is a jumper in front of the battery. In the photo on the right, although there is a bypass, there is nothing to shut off the battery: there are no ball valves

When connecting according to a two-pipe scheme, there are no problems: there are taps, close them, remove the radiator. With a single-pipe system, but with horizontal wiring, jumpers are also needed. But, in their absence, you will freeze your apartment.

In general, a bypass is a very necessary element: if necessary, it allows you to install a thermostat (thermostat) at the radiator inlet, with which you can maintain a constant temperature in the room. Without this jumper, the installation of control devices is prohibited. It's just that without it, it turns out that you regulate not only the temperature of your battery, but also the entire riser, which the neighbors are unlikely to like.

But only the presence of a bypass does not guarantee the possibility of disconnecting the battery during the heating season. There should also be ball valves on the supply and return. Moreover, it is better to take full-bore taps for heating batteries. There are also standard ones. In them, the clearance in the open position is approximately 70-80% of the diameter. In full bore models, it is 100%. To ensure normal heat transfer, they are needed.

The battery can be disconnected at any time if there are ball valves at its inlet and outlet. But so that the heat transfer does not fall, it is necessary to install full bore models

If there is no bypass, to carry out all these works, you will have to turn off the riser, and this is not done soon, and even for a fee.

If necessary, close and remove the radiator

Work related to the removal of the radiator is best carried out after the end of the heating season. If work needs to be carried out during the heating season, a number of nuances must be taken into account. If you have a single-pipe heating system and vertical wiring, you can only remove the battery if there is a bypass.

Such a system can be identified by pipes, one of which comes from the ceiling and connects to the radiator, while the other exits the radiator and disappears into the floor. The bypass is a jumper connecting the incoming and outgoing pipes. This is a pipe of approximately the same or slightly smaller diameter than the main pipes. The principle of operation of the bypass is as follows: if the radiator is turned off, the water begins to flow through the riser, passing through the bypass without passing through the battery. In this case, the riser works, the heating in neighboring apartments does not turn off.

If the system is two-pipe, if there are taps, it is enough to close them, after which you can remove the battery.

Repair of a single-lever mixer with a ball block

Problems with a single-lever ball faucet are usually caused by a broken valve mechanism. The lever, fixed with a screw, is removed in the same way as in the case of a cartridge faucet. The domed metal cap, which is located below, fixes the entire valve mechanism in the body.Under the cap is a plastic cam that limits the movement of the control lever. At the bottom of the cam is a dome-shaped washer for a snug fit to the mixer ball. The device of the ball and the principle of mixing, we have already described above.

Disassembly order

• Remove the plastic red and blue pads and unscrew the lever as described above. The difference will be that the pin from which you want to twist the lever is not polymer and rectangular, but metal, with a thread for the screw fixing the lever.
• Unscrew the domed cap. It can be equipped with slots for a comfortable grip. But if there is no slot, use a screwdriver: rest it in the groove and gently knock it up and clockwise, tearing the part from its place. You can also use round nose pliers by inserting them into the grooves from inside the cap.
• After removing the cap, remove the cam with a figured washer. Clean them off with a rag.
• Take out the mixer ball and examine its valve part.
• Remove valve seats. They are easily removed with a thin screwdriver. With tweezers or a screwdriver, you can get the clamping springs under the saddles.

Typical Ball Mixer Valve Gear Problems

Leaks or excessive noise can be caused by the following problems:

• The inside of the dome washer or the seat in the body where the bottom of the ball rests is worn or heavily soiled. These spherical cavities must be thoroughly cleaned.
• Ball wear. It may show cracks, grooves. All this is caused by dirty and hard water with impurities of solid particles. The only way to fix it is to replace the ball.
• Valve seat wear. If they start to fit poorly on the ball, then they let water through. They also need to be replaced.
• Poor seat fit can be caused not only by worn seats, but also by loose springs. The problem is solved by replacing the springs with new ones.

Assembling a single-lever mixer with a ball mechanism

It is done in reverse order, with old parts cleaned and lubricated and new parts replaced:

Clean the faucet cavity.
Insert new springs into the saddles, place the assembly in the sockets intended for it.
The cleaned ball is lubricated with silicone grease. The ball is inserted into the mixer body.
A washer with a cam is installed. For proper assembly, there is a groove in the body that must be aligned with the lug on the cam.
Pure metal top cap bait and screw

It is important to avoid distortions.
Put on a metal rod and screw the lever to adjust the water.

Problems with the swivel spout

If water from a single-lever faucet flows above and below the swivel spout, this is due to worn seals. Rubber rings are used as seals, less often - cuffs. To replace the rings, you need to disassemble the mixer as follows:

• After removing the cartridge, you need to remove the swivel side of the spout from the body. How to do this will become clear when disassembling. In some models, this node is removed upwards. On the body, it is stopped by a special clutch. But more often, the spout block is removed downwards, where a corrugated flexible hose is attached. To remove the block, you need to disassemble it up to dismantling the mixer from the sink or sink.
• On the lower side of the dismantled mixer, you need to unscrew the ring-shaped nut and remove the fluoroplastic ring located under it.
• Now you can remove the spout block from the body by pulling it down. Worn rubber seals will be found at the joints with the body.You should purchase to put the same new ones, and at the same time replace the fluoroplastic rings on top and bottom before installing the mixer.

Crack in the hull

This malfunction is immediately noticeable, and requires the replacement of the entire mixer. Some home crafters resort to silicone sealant to "repair" the case. But this is a temporary measure. Soon, you still have to go to the store for a new mixer.

Clogged aerator

If, with fully open taps, you observe insufficient pressure, then there may be several reasons. This is a blockage in pipes and inlet hoses, and simply poor pressure in the water supply network. But it can also be a clogged aerator on the spout pipe. To repair, unscrew the aerator. If hand effort is not enough, then use an adjustable wrench. The aerator has slots for twisting. On the mesh inside, you will find a lot of solid particles and layers that prevent the flow of water and reduce pressure. The mesh can be cleaned under running water.
