Compact sink siphon: flat and short versions. Siphon for the sink.


The sink over the washing machine is a stylish and convenient option for a small bathroom.

Arranging a small bathroom involves one problem - a minimum of space. Which leads to a cabinet with a mirror, a sink with a cabinet and even a sink with a washing machine. Each of the ways to save limited space requires a special device design.

For example, a sink on a washing machine: the sink and the siphon must be flat, assumes a special device so that the connection is not difficult. Such shells are often called water lilies.

Advantages of a combined sink and washing machine

An original way to save space, like connecting a washbasin and a washing machine, has a number of advantages and disadvantages.

Pros of a sink over a washing machine:

  • great space savings even in the smallest bathroom;
  • the space under the sink is often not used, and the washing machine installed there increases the usable space;
  • modern water lily shells are available on the market in a wide variety; will perfectly fit into any design.

A pair of sinks and a washing machine aims to save space in the bathroom, which they successfully cope with.

Disadvantages of a sink over a washing machine:

  • to install a washbasin on a washing machine, a special flat siphon is required; if it is not included in the kit, it is rather difficult to find such a device; a similar problem will arise when replacing the siphon;
  • the drain of water in the water lily sink is often facing backwards, which will cause you to face stagnation of liquid in the bowl; also, the drain can be arranged on the side, which can lead to stagnant water;
  • if the dimensions and installation rules are not followed, the edges of the washing machine may protrude beyond the edges of the bowl, which will lead to inconvenience; it happens that you cannot get too close to the sink because of the washing machine, but this is a matter of habit;
  • to create such a pair, not only the sink must be unusually flat, but the washing machine itself must not exceed the standard 70 cm.

There are many disadvantages, as we can see, but they are all petty and getting used to them is a matter of time. How much space you save is worth the inconvenience.


Flat sink above the washing machine.

The main thing, a snag that can confuse you is a flat siphon. If you did manage to purchase it, installation is straightforward. Today's very flat models can now be secured with conventional sealant. However, super flat siphon models are difficult to find. Therefore, buy a regular flat mechanism that attaches to nuts and bolts.

Choosing a flat siphon

Today, diversify plumbing so much that it is already difficult to surprise us with something new.

The entire line of siphons is presented on the market: from simple and cheap to exclusive and expensive models.

Common patterns:

  • corrugated;
  • bottle;
  • flat;
  • pipe;
  • double or triple;
  • hidden;
  • with overflow.

Each of the types has a number of advantages and exclusively for its purpose.

To install the washbasin on the washing machine without hindrance, you need a flat siphon.


Flat sink siphon.

The flat siphon comes to the rescue in case of an acute shortage of space in the bathroom.A washing machine, boiler, cabinet can be installed under the sink only if a flat mechanism is used. Or perhaps you are not installing anything under the sink, you just want to minimize pipe protrusions.

There is a special model of split jet siphon that must be installed regardless of your design decisions. In catering establishments, cafes, restaurants, bars and any other places where food is produced, the installation of a flat siphon is mandatory according to sanitary standards.

The siphon should be made of high-quality material (plastic) that is highly resistant to elevated temperatures and does not deform when it drops.

A piece of plumbing, like a siphon, is mounted between the sink and sewer pipe... Carry out the installation yourself, but not desirable, inexperience in this matter can affect the drain.

If you decide to mount the device yourself, check at the end of the work how well and reliably all the parts are fastened. To do this, turn on the tap and observe the operation of the flat siphon for 30 seconds.

The flat siphon is used not only for washbasins combined with a washing machine. It is also great for low showers or Jacuzzis.

These siphons are usually made of two materials: plastic and metal. Plastic can be elastic, hard, and soft. Metal siphons are not as popular as plastic ones. They are not as easy to use and unnecessarily expensive.

Therefore buying a siphon. Give preference to a plastic model: it will not rust, corrosion will not appear on it, such a siphon will be stronger and more durable. A plastic siphon is much easier to clean than a metal one.

Benefits of the flat siphon:

  • high practicality of the device;
  • simple construction;
  • ease of installation;
  • takes up a minimum of space under the sink.

Among the disadvantages of a flat siphon, only one point stands out: to clean such a model, you will need to completely dismantle the siphon and re-fix it.

Installation features

The optimal location of the drain hole and the drain itself is the corner of the sink. With this arrangement, water does not enter the washing machine, even if the siphon loses its tightness.

With a standard siphon, the drain will be in the middle of the sink and there will always be a risk that water will flow directly into the washing machine.

A small sink above the washing machine is a popular solution for small bathrooms today.

Experts say that installing a flat mechanism is no different from installing a standard model. And it is also recommended to be especially vigilant when tightening the screw, do not pass the plastic parts.

Design flat device simple and practical. It is easy to use, and installation problems should not arise.

The choice and installation of plumbing is a very important and serious process.

Every rubber band, nut or bolt requires your attention. Not to mention the siphon under the sink. Such an important detail will determine the quality and durability of the sink, and the flat siphon will also increase the usable area in the bathroom.

A siphon is a drain device designed to prevent sewage odors from entering the room. Flat is usually used when you need to save space under the sink or when it is not possible to install another type of device. It collects water in a special chamber and prevents nasty sewer odors from entering the room. The device is easy to use, does not accumulate mucus and other deposits, and is also quite durable and affordable. It can be used both for kitchen sinks and for installation in bathrooms near washing machines or washbasins. You figured out what a flat siphon is, now you should better understand the principle of its operation, as well as the design of this device.

Design and principle of operation of the device

Each plastic siphon, regardless of the type and location of installation, contains the following components in its device:

  • protective grill;
  • thick rubber pad;
  • liquid outlet branch pipe;
  • fasteners and connecting elements;
  • body;
  • drainage into the sewer;
  • plastic adapter;
  • small and large flat rubber as well as tapered gaskets;
  • decorative plastic cover or screen.

The design of the flat siphon has certain secrets. In cheap models of the device, black gaskets are used to protect against odors from the sewer.

They don't look as aesthetically pleasing as the white ones used in expensive siphon models. In addition, if you decide to install this device in your home, then you should stop at the choice of fasteners (nuts and bolts) made of stainless steel. Thanks to this solution, your device will last longer.

The principle of operation of a flat siphon is no different from other similar devices. It can be described as follows:

  1. first of all, water from plumbing or washing machine enters the drain;
  2. after that, it passes through the sump pipe;
  3. eventually, the water is discharged through the outlet.

As mentioned earlier, the flat siphon is designed to block the entry of odors into the room.

This is possible only if its installation was done correctly, and it was possible to create a water seal, which does not allow unpleasant aromas to pass through. The smell from the sewer can enter the room only if the owners of the apartment or private house were absent for some time. The water that accumulates in the unit gradually evaporates, which leads to the transmission of odors. To eliminate this, on arrival home, you need to drain the water through a siphon, which is connected to plumbing devices, and then after a certain period of time the smell will disappear.

Varieties of siphons and materials from which they are made

Besides flat, there are other types of siphons. These include:



In addition to dividing by type of design, devices are classified according to the materials from which they are made:


Technical Parameters of Flat Siphon

The flat siphon has its common specificationsto look at when making a purchase for a device. These include:

  • product certification - each device must have certificates that confirm the quality of the product;
  • warranty - a quality device always has a warranty for a certain service life;
  • type of application - for washing, shower, etc.
  • material - the consumer chooses, guided by his own preferences or needs, in any case, the selection of the material from which the siphon is made is individual;
  • additional drain - guided by the needs, the consumer chooses whether he needs an additional drain for other plumbing items or household appliances, or not;
  • the dimensions of the outlet and inlet openings;
  • neck material;
  • siphon color.


Strengths and weaknesses of the siphon

Now we should talk in more detail about the advantages of a flat siphon in comparison with its counterparts. These devices are made of plastic. This means that the device has sufficient strength to be successfully used in everyday life. This device combines high quality with low cost. The device perfectly copes with its main task - not to let unpleasant sewer odors into the room. In addition, it has the ability to connect additional drains.

Flat siphons are easy to clean from dirt. The device is easy to mount in the right place for this. It does not enter into any reaction with detergents or cleaning agents that enter the drain along with water, does not accumulate mucus and limestone deposits. They can be installed in the kitchen or bathroom, although the most important advantage of the flat siphon is the ability to install it even in the smallest room. In any places where it is impossible to install similar devices of a different design, just such units are used.

The disadvantages of a flat siphon include the difficulty of cleaning it. In order to clean this device, you need to completely dismantle it, and this is not always convenient. In addition, dismantling can take a lot of time and effort.

When choosing a siphon, it is important not to make a mistake, and in order not to make a mistake, you need to follow the following selection recommendations:

  • decide on the installation site. It is very important to understand that not every device can fully cope with its duties under certain conditions. For example: pipe siphons are not suitable for installation in small space, while flat ones easily get around this difficulty;
  • type of application. There are universal, and there are narrow-profile device models. The former can cope with any type of plumbing or household appliances with which they will be completed. The latter, in turn, can only be used with a single unit. For example: flat ones are completed with any type of plumbing or household appliance, and pipe ones - only with plumbing, since they quickly become clogged in the kitchen;
  • material. The material plays an important role because the strength of the device depends on it. The stronger it is, the more expensive the siphon will cost.
  • additional plums. When choosing, be sure to pay attention to whether the unit can have more than one drain and connection.

The siphon is one of the most important parts of plumbing. It prevents unpleasant sewage odors from entering the room. The flat sink siphon is very compact and is ideal if space is limited and you want to save space.

Advantages and disadvantages of flat siphons for kitchen sinks

The advantages of a flat siphon under the sink are:

  • simplicity of design;
  • ease of installation;
  • takes up a minimum of space.

The downside of the part is the need for complete dismantling in case of cleaning from dirt.

Material for making a flat siphon for a sink

Products are made from the following materials:

  1. Plastic (polyethylene, propylene). Is considered the best material for a flat siphon, since it does not give in to decay and corrosion, it has good strength.
  2. Metal. Products made of bronze or brass are used in rare cases, as they may oxidize over time.

Particular attention should be paid to the choice of a flat siphon for a sink. When purchasing it, you must carefully examine all the assembly details, including gaskets and screws. In the case of installing a sink above, for which a flat siphon is used, it is necessary to exclude any shortcomings when fastening parts, as they can lead to leakage.

You can install the siphon yourself. It is installed between the sink and the sewer pipe. The parts must be firmly fastened. It is imperative to carry out a check after installation, for which you should turn on the tap and observe the siphon.

The correct selection of your washbasin flat siphon will ensure functionality and convenience in your room.

Plumbing is the main part of home improvement. Perhaps one of the most important parts of plumbing is the siphon. Regardless of the configuration, the siphon works like a kind of water seal, since water is constantly present in its curved part. Water, in turn, prevents the penetration of unpleasant odors and gases from external sewage into the room. If we are talking about saving space, then the ideal option would be to purchase a flat siphon for the sink. Such a product serves as a way out in the case when you are limited in the area of \u200b\u200b\\ u200b \\ u200bthe room and are trying to maintain the convenience and functionality in the house.

Installing a plumbing siphon is not a complicated process. Speaking about its fastening, it should be mentioned that progress in this case does not stand still, and today there is even an option with an installation based on a sealant (ultra-flat siphons). Of course, you need to look for such models, so we all choose the usual installation option with nuts and bolts.

Product types and criteria

Today, manufacturers can offer a large selection of this type of plumbing devices: from simple to exclusive. The price category also varies depending on your requirements.

Speaking about siphons in general, it is necessary to disassemble their most common types:

  • bottle;
  • corrugated;
  • flat siphon under the sink (bath);
  • pipe - look like a curved pipe.
  • double or triple, which are able to provide the ability to connect with the required equipment (for example, a washing machine and dishwasher);
  • with overflow;
  • hidden (located in the box).

Flat siphon with overflow device

Let's consider in more detail the device and application of flat siphons. As already mentioned, the advantages of flat siphons are most fully visible in the event of a shortage of working space. In the case when a boiler is installed under the sink, or there is simply a lack of space, then the best solution is to purchase a flat siphon.

Purpose of siphons with jet break. for special applications, for example, in places of public catering, cafes, in various industries where food products are manufactured, etc. In general, the installation is carried out when sanitary standards the use of conventional siphons is not permitted. All these devices must be made of high-quality plastic that is resistant to high temperatures in order to avoid further damage, deformation or breakthrough.

The sanitary siphon is installed between the sewer pipe and the sink. As it was already emphasized earlier, its independent installation is not such a time-consuming and complicated process. The main thing is that all the parts are securely fastened and tested (after installation, it is enough to leave the tap turned on for half a minute and observe the siphon).

The flat siphon is usually used when installing bathtubs with limited space under the drain, because it has a flat shape. For example, a flat siphon for a Jacuzzi-type bathtub will avoid the arrangement of the so-called pit, or, in other words, a characteristic depression in the floor when connecting the bathtub to the drain.

Flat bath siphon

The main materials for the manufacture of the product are:

  1. plastic (hard or soft, elastic). The most common option;
  2. various kinds of metal (applicable in special cases or at the discretion of the manufacturer). Metal siphons are not always convenient to use, and their price is too high.

Of course, the best material for products of this type is plastic (for example, propylene, polyethylene). The advantages of this material are obvious: it does not lend itself to decay and corrosion, too, great wear resistance and strength. Some craftsmen use brass and bronze pipes, but there is one significant drawback: their surface begins to oxidize over time, which eventually leads to the accumulation of dirt and the appearance of a specific smell in the house.

The practicality of the flat model of the siphon lies in its simplicity of design, ease of installation, it requires a minimum space under the sink. However, when cleaning the siphon from dirt, you will be forced to carry out a complete dismantling, which is perhaps the only item in the category of disadvantages of flat siphons.

Thus, this model of the siphon can be designated as specific, because in everyday life we, most often, acquire classic models that are already familiar to us.

The flat sink siphon is also used when installing the washing machine under the sink itself. In this case, we can gain the distance between the car and the bottom of the sink.

Installation and ratio of siphons with various types of drainage

Consider some of the technical characteristics of siphons, especially flat ones. The best option would be when the drain is located in the very corner of the sink. In this case, when the siphon becomes leaky, water will not get into the washing machine. In the usual version, the drain will be located exactly above the machine, and here you need to pay attention to the very reliability of the connections during the installation of the siphon.

The installation of a flat siphon usually does not differ from the installation in the standard version. So, the sealing gum located between the sink and the lower pipe is securely pressed with a screw. Next, a grate is installed on the bottom of the sink, through which a fastening screw passes. When tightening the screw, be especially careful: plastic parts do not always withstand high pressure and load, so do everything gradually and carefully.

Usually, imported sinks are already supplied with siphons of this type. In this case, pay special attention to the drainage details: if the details are not standard, some difficulties may arise in case of repair.

Another question is when there are various structural elements that interfere with the installation of a conventional siphon (wall elements, pipes, etc.) - in this case, the use of a flat siphon for the sink will help you out.

Of course, you will need to first consider the features of the sink itself. Any siphon will work with a simple sink. But if you have chosen an exclusive option, then it is better to purchase a siphon complete with a sink.

The ability to pass water is also important, and the more it is, the better. It all depends not only on the number of additional devices connected to the siphon, but also on the water pressure in the mixer.

Therefore, the more connected equipment, the larger the siphon cross-section. Taps on their own bandwidth also have to withstand heavy loads. Otherwise, we run the risk of constantly observing the "dam" in the shower or bath. Thus, the shallow section on the siphon is completely unsuitable for such work.

For most types of bathtubs, a flat siphon will work best (in case standard size between the drain and overflow holes). A correctly installed siphon will ensure a reliable and comfortable release of water from the bath, and also prevent excessive filling of the bath itself with an excess of water (through the hole located at the top, excess water is drained into the sewer). When choosing a shower cabin with a non-standard pallet solution, pay attention to what type of siphon is included in the kit. This will help avoid further installation problems.

By itself, the design of a flat siphon is quite convenient and practical, because each of us is trying to improve our life without prejudice to the living space. In this case, beauty and aesthetics must also be present. Good plumbing will always help in solving the problem of arranging common areas.

Flat sink siphon

The choice of plumbing is a very important part of a room renovation. Therefore, it is necessary with full attention to select even the most insignificant, in your opinion, element. Along with installing basic plumbing, choosing a reliable siphon must always be correct. Installing this kind of detail usually doesn't take a lot of time, but it should always be careful. Deficiencies in fastening parts, even the smallest ones, can lead to irreversible consequences. For example, when installing a sink over a washing machine, it is important to prevent leaks so as not to ruin the appliance. Also, do not forget to take into account the features of flat siphons when working with it. When purchasing a siphon, you need to pay attention to all assembly details, from gaskets to screws.
