In any apartment there is at least one washbasin - an object without which no bathroom can be equipped. However, in order for the object to function properly, it is necessary to equip it properly.
One of the integral components of the structure of the washbasin is a siphon - an object that is entrusted with the function of preventing overflow of water, as well as eliminating unpleasant odors. Next, we consider the features of choosing a siphon, as well as the basic rules for its installation.
Device
First of all, it should be noted that the siphon is a rather simple design, which in its appearance resembles a series of pipes interconnected by flasks. In some cases, this drain element is presented as a single continuous pipe.
Speaking about the design features of the siphon under the sink in the bathroom, it should be noted that it has some standards that are respected for a long time. In accordance with them, the design of the siphon is:
- grid;
- rubber pads;
- connection of a branch pipe or a protective lattice;
- branch pipe;
- branches for the sewerage;
- connecting nuts;
- body.
Next, we consider the features of each component individually.
Speaking about the grid (protective grid), it should be noted that it is a certain element that has 5-6 holes with a diameter of 1 cm. It is installed directly in the wash basin. This element is visible to the naked eye - it is in the place where the water leaks. The basis of this part can be made of both plastic and metal.
As for the rubber pad, it is designed to prevent water from seeping from the washbasin to the floor. Practice shows that the color of such gaskets directly depends on the price and quality of the entire siphon: in expensive products they are presented in white, and in cheap - in black.
As for the branch pipe, which is part of the siphon into the sink in the bathroom, it serves to connect other devices to the pipe, connected from other plumbing elements installed in the neighborhood. Between the nozzle and the protective grill there is a connection, presented in the form of a screw, the diameter of which is 8 mm. Also, in addition to the pipe, other bends can be installed, presented in rigid or corrugated form. Additional elements of the siphon can also be connecting nuts made of the same material as the base of the structure. Most of the recommendations of specialists note that nuts of a high-quality design must be made of stainless steel, since in case of damage they will have to be replaced with a new one.
In devices of the type under consideration, various decorative linings are also installed, as well as reservoirs into which waste entering the sink accumulates.
As for the base of the siphon, it is the entire body of the product. We will talk about what they are next.
Types of siphons
Choosing such an element of discharge for your apartment, you should pay attention to the abundance of varieties of these structures. Currently, these types of siphons are distinguished:
- corrugated;
- dry
- flat;
- bottle;
- tubular.
Each of the listed design variations has certain features, which we will discuss later.
Corrugated Siphons
Practice shows that most often corrugated siphons are found on the Russian market. Designs of this kind are made of plastic having a folded structure. Due to the structural features, the structure has the ability to perfectly fold and unfold, shrinking into a tube of the required length. An additional advantage of this type of construction is that it can be curved in any way. This allows you to place it anywhere. Practice shows that a siphon with a plastic corrugation is best suited for a sink, as it is squeezed into any place without problems and is quite simply connected to the drain.
The design of the corrugated siphon is distinguished by its simplicity: it has a base, as well as a number of connecting nodes. The main advantage of this structure is that there are almost no leaks in the pipe of this type.
However, practice shows that the design of the siphon for a sink with plastic corrugation has some negative features, which are manifested primarily in the low degree of resistance to sudden changes in temperature. Also, when using such a design, it is necessary to take into account that when fat enters it, a clogging of the pipe occurs, to eliminate which it is necessary to dismantle the entire structure, clean it and install it back, or replace it with a new one.
Pipe siphons
Specialists in the field of construction often note that a tubular design, which is presented in the finished version and does not lend itself to any deformation, will be an excellent option for a siphon for a sink in the bathroom.
Tubular siphons are presented in the form of a curved tube, which is made of metal or high-quality plastic. It should be noted that in this design there is always a bend in which a water shutter is formed, however, as a rule, it has a small size and shallow depth.
The pipe siphons, according to the people who operate them, have a number of disadvantages, which are manifested in the form of frequent formation of an unpleasant odor coming from the structure, as well as constant clogging of the passage, as a result of which you have to constantly disassemble the riser and clean it.
Siphons are not recommended for the arrangement of kitchen sinks, as they most often get food debris, as a result of which they will constantly need to be cleaned. A big minus of such structures is that they are large, because of which, under the sink, as a rule, nothing is placed except for a siphon.
Tubular siphons are an ideal design for a double sink. Some of them have double protective nets.
Bottle Siphons
Among the popular designs are bottle siphons, which got this name due to their unique appearance - the middle part of the tube has a protrusion, presented in the form of a bottle.
Similar products are characterized by certain installation and operation features. So, the installation of these structures is best trusted by professionals in the field of plumbing, but their subsequent disassembly and cleaning can be done independently - such processes are not difficult.
Experts often note that bottle siphons have one simple feature - they can easily connect the drain of any other device, for example, a washing machine or dishwasher. It should be noted that in this situation, the connection occurs directly, without the use of extra taps for sewage.
Among the positive qualities of the structure under consideration is also worth mentioning the fact that it has a special element - a branch, in which all the garbage falling into the pipe is collected. It should be noted that the existing blockages can be obtained without much difficulty, removing only the lower part of the structure, without dismantling the riser completely.
Thanks to all the features and advantages of the design, it is often used to equip double plumbing fixtures, as well as to equip overflow sinks.
Dry siphons
One of the latest innovations in the field of plumbing is a dry siphon. This type of design gained great popularity immediately after its birth, due to its ability to prevent stagnation of water in the tube, so that there is no unpleasant odor.
Dry siphons are often used in cottages, as well as in such rooms where the water supply is strictly limited and there are certain problems with heating.
The peculiarity of the action of the siphon of the type in question is that when water enters it, a membrane made of rubber begins to open due to the movement of the stream. After the water supply is shut off, it is compressed, as a result of which the flow hole is simply blocked.
Hidden and flat siphons
Considering the varieties of siphons, you should definitely pay attention to such a variety of designs as flat. This type of sink siphon is used in a situation where for some reason it is not possible to install a corrugated or bottle siphon due to their size. Such designs are created primarily from plastic. Due to the small size of the flat sink siphons, they are most often used in small bathrooms.
The main advantage of hidden siphons is that such structures are not visible to others. As practice shows, most often they are placed inside special boxes, niches and walls. As a rule, such niches and boxes are mounted next to the sinks.
What siphons are made of
Plumbing experts strongly recommend that you pay attention to the material from which the structure is made - this is the primary indicator of its quality. Let us further consider the main features of each material.
Modern plumbing stores are ready to offer siphons from the following materials:
- chromium;
- brass;
- copper;
- bronze;
- plastic.
Practice shows that chrome-plated siphons are the most popular - they are the most durable and retain their qualities for a long period. Moreover, many people are captivated by the beauty of the appearance of such products. In the interior, this element is amazingly combined with towel dryers, pipes and other integral elements of the kitchen and bathroom, made of metal. When choosing a chrome, copper or brass construction, it is worth remembering that it needs proper care, otherwise the siphon will quickly lose its appearance.
As for the plastic siphons for the sink, they are less durable than metal structures, but, despite this, they are in fairly high demand due to the mass of positive qualities characteristic of them.
It is worth noting that plastic siphons are lightweight and also low cost. In addition, such structures are quite easy to disassemble and clean, and they can also be installed independently without much difficulty. The advantage of siphons made of such a material is that no calcareous deposits form on their inside, which now and then appears on metal products.
A significant drawback of plastic siphons is that they are subject to mechanical stress from the outside. That is why they need cover with ceramic elements or special boxes.
About sink siphon sizes
Speaking about the sizes of the structures under consideration, it is worth noting that they differ in their diversity. In that case, if it is not possible to calculate the exact length of the tube, then it is worth giving preference to those designs that can be deformed based on personal preferences - corrugated.
Speaking about the sizes of siphons for a dry-type sink, it should be noted that at present their list is very limited - manufacturers produce such designs of two types: 32 and 40 mm. When choosing other types of structures, it is necessary to make the most accurate measurements. So, for example, in fact, it is necessary to clearly determine the size of the chrome-plated siphon for the sink. After all, such material is not amenable to deformation.
How to choose a sink siphon by size? In this case, you should pay attention to what design throughput is necessary for a particular situation. It is also necessary to take into account the total number of sources connected to it, as well as the degree of supplied water pressure. In the event that during operation of the siphon a powerful stream of water from several sources will pass through it, it is worth giving preference to those designs that have a large cross section.
Otherwise, if the size of the sink siphon in the bathroom or in the kitchen is small, then you may encounter an unpleasant phenomenon in the form of a flood. It is also worth paying attention to the fact that when planning an increased load on the device, it is better to give preference not to plastic or flat elements, but to metal. A small siphon for a sink can be suitable only if one and rather weak stream of water gets into it.
Siphon Recommendations
Experts in the field of installation and maintenance of plumbing often give a lot of advice regarding the correct choice of siphons for sinks. What should I look for when choosing a device? Let us consider some of the main points below.
First of all, the buyer should decide what type of sink he chooses. So, if there is an empty and visible space under it, then it is worth giving preference to products made of metal, which look beautiful and quite aesthetically pleasing. As for the plastic structures, they look unattractive, so they are best used so that they are covered with something.
Despite the fact that the siphon is a relatively small part, it is still worth choosing it so that it fits perfectly with the overall picture of the interior. If in the bathroom there is a washbasin of a laid-on type (on a countertop), as well as a product made of stone, ceramic or glass, then in this case it is worth giving preference to a design made of metal - the elements will look very harmonious with each other. As for the type of product, it is advisable to give preference to bottle or pipe - in this situation, they look quite expensive, and they are also easy to use. When choosing a design, it is advisable to remember that modern manufacturers offer a wide selection of product colors, this allows you to select them for a certain picture of the interior.
When choosing a siphon for a sink, the size of the bathroom or kitchen must be taken into account. In the event that the space is small, then the corrugated type design is perfect for it - they can take any shape, as well as be located on any area. Practice shows that when using this type of siphon next to the sink, without problems you can place other objects that need draining water.
When choosing a siphon for a summer residence or a house in which there are problems with heating, you need to pay attention to the dry type design.
When choosing an object, one should pay attention not only to the type of product, but also to its throughput. Practice shows that a siphon for a sink of a standard size will not work if a stream of water from different objects with high pressure passes through it. In such a situation, it is worth choosing a design with a non-standard section diameter.
Modern siphons offered on the market can be divided into smooth-walled and ribbed. Manufacturers are increasingly recommending preference for smooth-walled products, citing the fact that they produce less clogging.
Some siphons have a check valve in their design. Its main action is aimed at preventing the reverse flow of liquid, as a result of which an unpleasant sewer odor can be avoided. Installation of this type of siphon is appropriate if the pipes are located at a slight slope.
During the purchase process, it is also worth paying attention to the cost of the product - it determines its quality and, as a result, the duration of the service life. Practice shows: metal products are much more expensive than plastic, but their service life is longer, which is caused, first of all, by resistance to mechanical influences from the outside, as well as the strength of the material.
When choosing a siphon, it is necessary to pay on those configurations that have a special purpose. So, modern manufacturers supply special siphons for kitchen sinks to the plumbing market , the size of which is fully consistent with the standard throughput, and the tubes themselves often have protection against fat sticking and excessive clogging.
What you need to pay attention to, having fully decided on the choice of product? When buying a design, you need to check whether all the parts are in place.In the event that a branded product is purchased, then a quality certificate must be included with it. It must certainly reflect the characteristics of the product and the material from which it is created. Also, a warranty card must be attached to any good siphon. By the warranty period stated in the document, you can determine the quality of the structure: the longer it is, the more the manufacturer is confident that the goods provided by him will last for a long time.

- First of all, put the o-ring on the pipe, placing it with strips up. The second ring that comes with the kit should be pulled over a metal mesh, which then needs to be placed above the sink.
- Next, you need to adjust the siphon under the drain hole available in the sink.
- Screw in the grate.
- Using a rigid tube that comes with the siphon, you must connect the assembled structure to the sewer. It should be noted that at this stage the process is much faster with respect to the corrugated pipe.
- At the final stage, it is necessary to let water through the siphon, checking the tightness and correctness of its installation.
