Rigid eyeliner for a bathroom faucet. Water supply for mixer - rigid or elastic

A distinctive feature of this connection is the rigid attachment of the mixer and pipes. Some masters consider it more aesthetic than flexible liner, although it is more a question of personal preferences and tastes.

pros

TO positive sides   Connections of hard type include:

• Looks stylish enough compared to flexible;
• Long operational period, which is about 20 years;
• High quality of materials that are not corroded;
• The installation is quite convenient (although it has its own nuances, so it can not be called a plus);
• The product is reliable;
• Due to the smooth surface, keeping the liner clean is not a problem. The dirt on the tube does not accumulate;
• The device is not afraid of thermal and chemical influences, it can withstand higher temperatures and swings than flexible counterparts.

Minuses

Whatever one may say, but there can not be no shortages.

We noted that the installation - a controversial issue, because it is also worth attributing to the minuses. Performing it is quite problematic, since you are limited in moving the liner. Actually, this forms another drawback - stationarity. The product does not bend, does not lend itself to even slight deformation, which would allow for a more correct, aesthetic installation.

In other respects, even experienced specialists do not find serious shortcomings, which could be characterized by rigid podvodku.

Kinds

Classify the types of rigid podvodki can be based on the materials from which it is made in our time. It is a tube of metal. This metal, in turn, can be:

• Brass;
• Steel;
• Copper.

Which option is more reliable - it's up to you. In many respects it depends on the manufacturer and his degree of responsibility for his own products. The most important thing is that the metal possesses anticorrosive properties,   and was not a cheap forgery. Unfortunately, some firms use ordinary black metal, which eventually rusts. And to hide this fact, cover it with special paints and compounds. As a result, the tubes look like steel, copper or brass.

When choosing a rigid padding for your mixer, try to observe a few simple rules. They are recommendatory in nature, but they allow you to make a really correct purchase.

• Material.   Carefully study the material from which the liner is made. In fact, steel, brass and copper have their advantages and some nuances, because the most important thing is the lack of forgery. If you are told that this is brass, you should be sure of the fairness of these words.
• The size.   Hard piping is problematic a bit in that it is demanding on the right size. Take into account the diameter of the water pipe and the inlet to the mixer. Some houses are equipped with non-standard communications, so before going to the store, make sure to take measurements.
• Length.   A separate topic for conversation. The bottom line is that you need to choose the right length. If the tube is short, you will have to buy a new one or weld the missing element, which is absolutely the solution for the most extreme case. If the tube is long, you can not fully install it, as the material does not bend. This is the main problem of choosing a rigid cabling.
• Manufacturer.Now the market has formed its elite of manufacturers of sanitary ware and sanitary equipment. Also, for sure, in your city there is a store that enjoys the greatest authority. It is desirable to buy products from them. Both the manufacturer and the distributor are not interested in losing credibility and clients. Because they try to offer high quality goods. He needs you.
• External aspects.   As a rule, try to hide the eyeliner from the eyes, by doing the skin, installing bathroom furniture and so on. But in some situations, the eyeliner remains visible, which means you have to pay attention to its design.
• Price.   Let's just say one thing - good hard-wiring is not worth a penny.

Installation

Following the sequence installation works, you easily connect the hard-wiring to your mixer.

• Determine the location for the mixer.
• Prepare the wall for the subsequent installation of tubes. Mark special strips to place the pipes. Make a stroba. Some tubes can pass through the wall, others - with a depression. Do not forget, the system will have knees, so note them on the wall beforehand.
• Collect the pipes. Predominantly even experienced domestic masters entrust this task to professionals. Anyway, do not forget to screw the eccentric at this stage. The rewinding is not required yet.
• Lock the old mixer to make sure the system is positioned correctly. Do not worry, on all models of mixers there is an identical distance between landing points.
• If you understand that everything is done correctly and smoothly, proceed to embedding the strob. To do this, you need a cement mixture. Also provide a layer for the subsequent application of the finishing material (since this is a bathroom, most of us use ceramic tiles).
• When the cement mixture dries, you can remove the old mixer, install a new one in its place.
• The final stage will be the surface treatment of walls and the installation of tiles. Ensure that all fasteners are tight so that there is no leakage during operation.

How to put instead of flexible

You probably can see for yourself that flexible podvodka is everywhere, almost everyone in the house, office and so on. Mount it easily, it costs a little.

But do many people know that it needs to be changed every 3-5 years?

This is due to the fact that the liner is aged, the hoses inside it are covered with cracks, the seals are out of order, the elasticity is broken. As a result, leaks are almost inevitable.

In this component, the hard analog of the pipeline is more reliable, able to work with more high pressure, and the operating period is several times higher.

Experts recommend that when repairing a bathroom, it is possible to connect hard wires in the future, even if the installation is now flexible. The sockets located under the sink must not be more than 0.5 m from the mixer. If this condition is not observed, you can use an alternative solution - corrugated tubes. But they must be made of stainless steel.

Unscrew all old tubes, remove the mixer and unfold the corner valves. Screw the tube into the mixer and make sure that everything fits in size. If not, unbend the product neatly or mark the points to cut off excess elements.

After you have pushed the tubes to the correct dimensions, check the axle ratio and assemble the system. The first to fix the mixer to the sink, after which the collets are tightened. Turn on the water and make sure everything is working properly. Also do not forget to check the system for leakage after a few days. If there is a decorative finish or furniture covering the system, do not install it yet. Only when you realize that everything is working properly, close the line.

Security measures

Specialists recommend the use of a pipe bender in the process of installing a mixer with rigid piping. This device allows you to draw the pipes without bending them too much. Inflection can lead to undesirable consequences.

Of course, one of the most important conditions for personal safety is the water blockage before the start repair work. Observe safety regulations, use protective equipment, gloves when working with metal.

Most often, when repairing a bathroom or kitchen, a hidden tap for mixing faucets is used. It is made using flexible hoses. But what if the design solution involves an antique-style interior where copper is used, or is it not possible to make a hidden water supply system? In such cases, the feeder for the mixer is rigid. It is worth considering this topic in more detail.

What it is?

The feed for the mixers is a product made in the form of a tube with a diameter of 10 mm. For such products, adapters, corner connectors, collet connectors are produced. Stainless steel mixers are available in sizes ranging from 200 to 500 mm.

Types of materials

There are several options for the execution of such products:

• Brass is an alloy of zinc and copper. The color is in the range from red to yellow. Good thermal conductivity, resistance to abrasion, resistance to corrosion and high temperatures. If no protective coating is applied, it may blacken over time.
• Copper. The color is golden-red. Has a high resistance to corrosion, but over time, in damp areas can acquire a greenish tint. Excellent thermal conductive and electrically conductive properties. Resistant to chemical attack, mechanical abrasion.
• Stainless steel. It has high anti-corrosion properties and strength characteristics. Has a shiny metallic surface.

As can be seen from the listed materials, the connection for mixers has several advantages.

Advantages and disadvantages

A number of positive properties can be distinguished:

• Resistance to corrosion. This is important for wet rooms, especially when using conduit on the piping.
• Smooth surface. Do not accumulate dirt, it is easy to clean.
• Resistance to chemical attack.
• Presentable view.
• Durability. In comparison with flexible, the service life is 4-5 times longer. The feed for the mixers is rigid and is used up to 20 years. Flexible 3-5 years, depending on the quality and the manufacturer.
• Hygiene. When interacting with water, it does not release harmful impurities into it.

The disadvantages include installation, but this is a controversial issue.

If the pipe size is correctly selected, then there should not be any difficulties during installation. The price for such products is much higher than the cost of analogues. But taking into account the service life, we can say that the cost justifies itself. Mobility - in case you need to move your plumbing or household appliances, you need a thorough rework. As you can see, the dignity of the hard cabling is obvious.

Scope of application

Stainless steel mixers are used not only for domestic purposes, but also for institutions that are subject to increased requirements health standards. This is due to the fact that the surface is smooth and conveniently washed. If we consider flexible liner, then it has an interlaced or corrugated structure, in which dirt and dust can accumulate. The use of pipes is most often in the following areas:

• Medical facilities: hospitals, sanatoriums, polyclinics, laboratories.
• Children's institutions: schools and kindergartens.
• Sports and health centers.
• Stations, airports.

This is only a number of institutions using such a podvodku.

Very popular is the use of such products for domestic purposes. Cranes made under the antiquity have a beautiful view, and to complement this effect, some designers use open-end liner made in the same style as the faucets.

In the kitchen, the intensity of the use of water supply implies a greater likelihood of equipment wear, plus the room itself is an aggressive environment. Care for furniture and equipment should be as comfortable as possible. Therefore, the connection for the mixer in the kitchen of a hard view is the most optimal option.

Nuances of selection

There are a number of subtleties for the selection of stiff eyeliner:

• Exact size. Deviation in greater or lesser side will entail difficulties with installation. Therefore, before buying should make accurate measurements. Also it is necessary to pay attention to the diameter of the fittings. They must match the size of the main line and mixer.
• Manufacturer. Before buying, you should review the reviews and options.
• Material. It all depends on the design idea and the price category, as well as visual preferences.

In general, the main difficulties can arise during installation.

Installation

As with conventional water supply, there are two versions of the system - hidden and open.

For the first one, you will have to trowel the walls, or sew them in plasterboard boxes. For open piping, provide a fastening system to the wall.

Before installation, the layout of the planned wiring is done. After the pipes are held, the masters install an old mixer and collect the entire system. Then all the fittings with the winding of the foil tape or the pakli are fixed. If the liner is hidden, then plaster. The time is allowed for the solution to solidify. Unscrew the old mixer and mount a new one. Turn on the water, check the tightness.

Install fully a new system   much easier than replacing flexible hoses on rigid ones.

Replacing the old liner

In the event that the decision is made to change to a rigid one, the pipes of the required length should be selected. If the size is non-standard, you should make a cut according to the required parameter. Then connect the collet. The details are worn before cutting.

There are cases when the length is less than necessary, you have to weld or buy a new one.

As a rule, the installation of rigid cabling is trusted by professionals, due to certain difficulties. An experienced master will determine how best to install with minimal risk of damage to the product.

Manufacturers

The market is replete with firms that specialize in the production of elite liners. One such manufacturer is Grohe (Germany). The "Groe" mixer feeder differs in ergonomics, reliability and durability.

There is another well-known manufacturer of this type of piping - Remer (Italy). This company has long been on the market and has a full production cycle. The quality control begins with the evaluation of raw materials and is monitored throughout the entire production cycle of the product. That's why the piping for copper mixers Remer has established itself as a quality product.

When buying such systems, you should pay attention to the completeness.

Branded original podvodki have a complete set, including gaskets. Counterfeits can be incomplete.

Cost and reviews

The price of hard-wiring varies from 1200 rubles and more. This cost is due to the high cost of material, in the first place. And, accordingly, the products of well-known brands will include the price for the brand itself. But it guarantees the quality of the products.

According to reviews, the main problem of installing such systems is precisely the fit of the size. Otherwise, consumers confirm the reliability and durability of such systems.

The pipes are called pipes or hoses, by means of which water from the water supply system is fed into the faucets or into a mixer. To connect the mixer to the water pipelines, three types of liners can be used: elastic, bellows and rigid type.

Elastic or flexible   water supply to the mixer by means of hoses in rigid braid - inexpensive in materials and simple in execution way to connect the mixer to the water supply system. It is this way that sanitation systems of bathrooms are performed in serially constructed residential houses. The length of the hoses is determined by consumer demand, and each manufacturer has the right to install it independently. As a rule, there is a wide choice in the trade network, and it is always possible to select the hoses of the required length for you.

The bellowsth run - by the design of a flexible hose made of corrugated metal - stainless steel. Unlike the metal hose rubber hose, the bellows hose does not have any other materials in its design, except for metal, so its service life is much higher. It can withstand the effect of water temperature up to 250 degrees, and is not subject to corrosion. As for the installation, the bellows hoses are no different from the hoses in metal braiding.

Originally hard cabling   It was used for public places, where a reliable and non-violating sanitary and hygienic norms are required for the water supply system: medical and educational institutions, places for recreation, transport stations and sports facilities.

The rigid water supply to the mixer differs also in the place of its installation. On the kitchen sink mixer is installed directly on the side of the sink, and the liner is under the sink. Such an installation is called the bottom line. In the bathroom, the picture is the reverse - the mixer is attached directly to the wall, not under the sink, since it is also intended for the bathroom and shower.

Advantages and disadvantages

The water supply to the mixer, as a rule, is not available for public viewing. It is hidden behind the plumbing equipment itself. Nevertheless, some masters recommend installing a rigid hose. They point out the following positive moments:

As with any medal, there is a downside and a hard water supply: firstly, this installation and it requires a very accurately withstand the distance   To the mixer, both for cold, and for hot water. Secondly, the mixer, together with the sink, becomes not shiftable, which will complicate the possible repair of the drainage device.

Choice of materials

Most often for the manufacture of podvodki use annealed copper food grade with subsequent chrome plating. Such a tube is easy to bend and it is convenient to lay any route to the feeding point of the water conduit.

To the internal wiring pipes, the rigid copper wire is connected in two versions: directly without transitions, or through adapters of various types.

A rigid connection for the mixer can be performed from metal or plastic tubes, their length is standardized, the minimum is 20 cm, and the maximum is 50. The tubes are reinforced, on the one hand, with a thread (nut or fitting) for connection to a mixer, and on the other hand to internal wiring pipes. Metal tubes can be aluminum, brass, copper and steel. The materials of all these tubes are resistant to corrosion, and the choice depends on you. It's important not to get on a fake material - painted, not natural. When choosing a hard line, you should pay attention to some details:

The most famous manufacturers of rigid cabling - german companies Grohe, Kaiser and Italian Remer. When buying it is necessary to check the completeness of the product, often a shortage of the product is due to the fact that the product is falsified.

Installation and safety measures

Install a rigid water supply can be hidden or in the open version, as you like. In the first case, you will either need to make grooves in the wall (shtrobit), or hide in trays from the decorative plate. If done in an open design, it is necessary to lay the fastening element under the copper collet in the wall at the installation site of the mixer.

When assembling be guided by the following description:

Upon completion of the installation work, the wall can be tiled with tiles.

Security measures. Before proceeding with the dismantling work, it is necessary to close the inside cranes in the bathroom, and to warn the domestic workers that you are working. Use gloves to avoid injuring your hands and use protective goggles when cutting metal. It is recommended to block apartment cranes also with long absence of tenants in the apartment, this can be saved from a possible accident on the intra-apartment water supply.
