Crane for washing machine: species overview and assembly instructions
After purchasing a washing machine, it must be connected to the water supply and sewage system. For this purpose, the use of a number of additional elements is provided, one of which is a faucet for a washing machine.
The role of this small detail used to connect the unit to the water pipe is extremely responsible. We will understand. how to select and install a similar system component.
The role of the crane when connecting the washer
The tap, which is used when connecting the washing machine to the water supply network, plays an important role.With it, you can instantly shut off the water in case of unforeseen circumstances.for example, when a machine breaks down, which can lead to leaks.
Even more dangerous is the water hammer in the water pipes: it can break the integrity of the elastic hose of the washing machine, resulting in a large-scale flood, which will cause justified disturbance of the neighbors.
To avoid this, it is necessary to connect the machine through the crane. This item is recommended to be placed in a prominent place in order to always have prompt access.
In an extreme situation, such a decision will allow to win a few minutes, which may be decisive to prevent flooding.
Kinds of the cutting devices
Specialized stores offer a varied assortment of cranes. Let us consider in more detail the most commonly used species.
Among them are:multiturnoverlapping the flow of water due to the movement of the plate, as well asBall Valves, which is turned on and off by moving a small ball installed inside the structure.
Ball valves have several advantages:
- high tightness;
- rapid response that allows you to quickly block the flow of water;
- simplicity of design, contributing to the prolongation of the operational period.
Another worth noting is the small size of this type of cut-off devices, allowing them to be used even in the most constrained circumstances.
Types of ball valves
There are several types of ball valves. Consider the main ones used to perform the process of connecting the washing machine at home.
Option # 1 - checkpoint
This mechanism has outlet openings on both sides, which allows to block the water, dividing the branch into two parts.
Appliances in this category can be installed on a separate pipe, which moves away from the general riser to any plumbing item, or used for tie-in.
Option # 2 - tee (three way)
As the name implies, such a device is equipped with three inputs-outputs. One of the holes is directly responsible for blocking the water flow, the other two are used to combine all water supply branches into a single system.
Such components, which can be of different sizes, shape and configuration, are usually used for tapping into a water pipe, where they are often combined with other devices, for example, with a mixer.
This feature is not available to a conventional flow valve due to the nature of its design.
Option # 3 - Corner
The design of this element corresponds to the features of the straight through fitting. With the help of this crane it is possible to divide the branch pipe into two independent branches located at a right angle.
Such an element is most often used when installing toilet bowls, however, it is also well suited for connecting non-standardly located washing machines.
The package of valves of all categories includes sealing rings, locking nuts, as well as swivel knobs, by means of which water is blocked and accessed. The last element is attached to the body of the part with a locking nut.
What type of crane to give preference?
When choosing a crane model, you must first proceed from the location of the machine. In small rooms, it is better to use the corner elements, with which you can reduce the space for connection.
If necessary, simultaneously connect two or more plumbing fixtures, it is better to use a three-way tap, and with an existing tap for a washing unit, a continuous ball valve.
It is also necessary to pay attention to the diameter of the device, which should coincide with the size of water pipes. And also take into account the features of the thread - its size, being on the outside or inside.
The last parameter can be omitted if the installation of the crane is supposed to self-threading.
No less important is the angle of rotation of the device: it is not very convenient to use the device, the valve of which closes in the direction of the wall, touching it.
Installation materials and tools
To connect the unit to the water supply network, it is not enough to choose a suitable valve. You must also stock up on tools, which include:
- Adjustable wrench, which is needed to perform installation work: connecting pipes and pipes, tightening the nuts.
- Plastic pipe calibratorfor fitting the crane when it is installed on the inset of the water pipe.
- Thread cutting penor a similar tool used for this purpose.
- Drill, file, screwdriverwhich may be needed for drilling and other work.
- Scissors for plastic pipesor Bulgarian for tapping of the faucet into the water supply system from plastic or metal elements.
In addition, you will needdouble hosewhich can be included in the package of automatic machine or purchased separately.
It is desirable that the length of such an element be somewhat larger than is required - this will allow you to have a small margin, which is necessary when rearranging.
If the hose is bought specially, it is better to give preference to the part having wire reinforcement, which makes it easy to withstand high pressure in the pipes.
Water filtermounted on the tap thread, which is connected to the tap of the water pipe. A small element allows you to improve the quality of water used, thereby reducing the risk of the formation of plaque and sediment.
If a liquid contains a large amount of mineral substances, it is allowed to use several filters at once.
Rings of consolidation, underwinding, tape FUM, spare bolts, without which it is difficult to do when installing plumbing products, - the listed kit will ensure reliable fastening of the faucet and tightness of this unit.
You should also consider the best connection option, taking into account the configuration of the room and placement of sanitary equipment.
Various crane installation schemes
Consider the popular connection options that you can perform yourself using a minimum of tools and additional details.
Scheme # 1 - Installation of the flow element
To install a faucet of this type (conventional or tee), you first need to shut off the cold water supply, which can be done with a faucet on the riser. After that, the remaining liquid is drained from the pipes, which may interfere with further manipulations.
The easiest way to install a flow valve on a separate branch pipe. As a rule, in this case a threaded bushing is already provided, to which it is easy to fasten the valve to the two-branch system connected to the filter. This element is attached to the inlet hose.
Having made all the manipulations, it is necessary to check the fasteners for leaks. If water is noticeable, you should redo all the connecting nodes, installing additional gaskets.
Diagram # 2 - End Mounting
If a special branch of the water supply system has been connected to the washing machine, you can connect the end valve using a tee (mortise clamp). This part is carefully screwed onto the pipe, so that the guide bushing is facing outwards.
After that, holes are drilled in the pipe, through which the connection is made to the clamp or section of the pipe where the valve is to be installed.
At the end of the pipe, a thread is cut that coincides in size and type with grooves applied to the tee. The outer threads are wrapped with a sealant (FUM tape) or flax, after which the valve is screwed onto the outer tube.
The hose attached to the automatic machine or bought specially is connected to the second end of the crane.
The other end of the hose is installed in a special hole, which is located on the back of the washing machine. The transport valve must be removed from it.
The assembled structure is checked for leaks. As a rule, the corner end of the hose is connected to the washing unit, while the straight end is connected to the water supply.
This option is more convenient, as the cleaning device is usually installed next to the wall.
Scheme # 3 - Installation of a crane with a pipe inset
A more complicated process is the installation of a crane directly on the pipe, since in this case it is necessary to cut the area.
For plastic construction elements, this can be done relatively easily using special scissors. Such an operation will require much greater effort if it is a metal pipeline: in this situation, a grinder will have to be applied.
To determine the size of the cut-out area, it is necessary to add the length of the crane and the size of the filter. After that, you can make a cut, and at the ends of the pipes cut the thread, which coincides in parameters with existing on the valve.
Behind this is the installation of the filter, which will protect the mechanism of the machine from impurities contained in tap water.
Then installation of the crane regulating water supply is carried out. To do this, remove the mounting nuts that are used to connect to the pipe from the part.
If the installation is carried out on a polymer construction, this part should be expanded with a calibrator before starting the manipulation.
Places joints are fixed tightening rings. The overlapped crane compartment is connected to the filler hose of the unit. After that, all nuts are tightened with an adjustable wrench.
It is important to pay attention to the force of fixation: a badly tightened or over-tightened bolt can cause enormous damage to the structure, becoming a source of leakage.
All joints are well sealed with sealing rings that come with a crane and / or filter, as well as fum-tape, flax fibers or other materials. The final stage is to check the assembled structure.
Special connection options
Separately, you can also mention non-standard types of connections of the crane. They are often used if it is not possible to make a traditional connection or an unusual method is the most convenient.
Option # 1 - installing a tap on the mixer
This option is found in practice because it attracts users with its simplicity and accessibility. However, it can hardly be called acceptable, since such a scheme has a large number of negative factors.
Such an arrangement of the crane adversely affects the condition of the mixer: the latter is experiencing an increased level of stress, which significantly reduces the life of the device. In addition, the combination of two devices complicates the use of both a tap and a mixer.
Experts consider it permissible to use such a solution only as a temporary option, but it is worth while to take care of the correct connection of the machine.
It is worth especially to warn the owners of apartments against the installation of a crane on the old-style mixers. To connect the device in this case, it is necessary to perform a complex procedure that requires material and time-consuming.
If this particular connection scheme is necessary, it is advisable to install a new modern mixer along with the installation of a crane.
Option # 2 - installation on old pipes
In older homes, the water supply network is often made of metal (usually cast iron). In this case, the ends of the pipes can be corroded, which complicates the installation work.
A similar problem of installing a crane can be done in two ways:
- File the pipe edges with files. This will align the ends of the elements, so that the laying of the hose can be carried out close to the pipe.
- Install extension cord,one end of which can hide the ends damaged by corrosion. From the other side, this part is mounted with a fixed hose with a gasket.
In any case, it is important to ensure the integrity of the structure and protect the pipes from further damage, for example, by coating them with anti-corrosion paint.But it is even better to immediately change the pipes so that the connection of other devices does not cause problems.
Option # 3 - double washing machine connection
In some models of washing machines, most often made in Japan and the USA, it is possible to connect to both hot and cold water.
Such options can significantly reduce the cost of electricity, since they do not need to specifically heat cold water, as in conventional units.
The poor quality of hot water prevents widespread use of such machines: it contains a large amount of mineral impurities, which not only increases the risk of mechanism breakdowns, but also reduces the quality of washing.
