Siphons for the sink in the bathroom: device, types, installation

Having decided to replace the plumbing in the house or install a new one, everyone begins to study bathtubs, washbasins, faucets, and no one remembers the detail on which the quality work of all this equipment depends. A mandatory element of most plumbing fixtures are siphons. It is to them that the tenants of the apartments should be grateful for the fact that the unpleasant smell of sewage coming from the sewer pipes does not enter the premises. In addition, the water plug inside these devices is a barrier that isolates the sewer pipes from blockages. However, when choosing a siphon for a sink in a bathroom, it is necessary to take into account not only its technical characteristics, but also its appearance.

Accommodation options

In the usual vision siphon - This is a nondescript item hidden under the sink in the kitchen. It is remembered only if the water that enters the sink from the tap has stopped leaving it or leaves it too slowly. Then they unscrew it, clean it, put it in place and again forget about it for a long time.

It is more difficult to hide the siphon in the bathroom, because the bathrooms of city apartments are so small that there is no place to install extra structures, for example, a cabinet under the sink. But you can find an exquisitely made designer siphon, which not only does not spoil the look of the room, but also decorates it.

The siphon is a detail without which the bathroom cannot exist. But before proceeding with the choice of this miracle, which has come down to us from the time of the Roman Empire, we need to study what it can be.

Design features of different types of siphons

The simplest design of the pipe siphon. This is a curved pipe in the shape of an “S” or “U” symbol, which can be collapsible and non-collapsible. Its advantage is the need for precise alignment with the inlet to the sewer, resulting in a rigid system of the drain device.

A classic of the 20th century is a bottle siphon. It is well known for its simplicity and ease of use and has the following features:

takes up relatively little space under the sink;
connection with a sewer pipe can be made as a straight or flexible pipe;
it is easy to disassemble during cleaning;
to rinse and remove sediment, it is enough to unscrew the bottom of the tank;
ideally protects sewer pipes from pollution.

The miracle of the late 90s of the last century - corrugated siphon - came into fashion along with interest in the redevelopment of apartments. This type of construction has its advantages:

makes it possible to connect non-standardly located sinks to the sewerage system;
very easy to install;
by bending the tube, you can form any slope and create a water seal.

Hidden siphons began to be used relatively recently. They entered the apartments along with built-in sewage systems. This is the same bottle device, but hidden behind a partition and ennobled by a stainless steel pipe located on the outside.

A novelty on the domestic market is a dry siphon, which functions not by creating a water plug, but thanks to a special membrane. When water enters, it opens and releases water, and then contracts again, tightly closing the flow hole, and not letting water and odors back.

Separate varieties

In addition to the design features of the structure, siphons differ in type and method of application:

If there is no place for a conventional drain device under the sink or it needs to be installed under the bathtub, then you can use a flat siphon. It is convenient for installation, takes up little space, perfectly retains odors, but it has one drawback: in case of blockage, you will have to disassemble the entire structure.
In connection with the increase in the number of household appliances, siphons for the sink began to be produced with two or even three separate side fittings. Thanks to them, you can connect a washing machine and a dishwasher to one drain at the same time.
For kitchen sinks, complex fixtures are made that combine two or more nozzles for connecting to sinks with several sections.

How to choose a siphon

A siphon is a product that is made from different materials:

cast iron;
nickel;
bronze;
stainless steel;
brass;
plastic and many others.

You can opt for any of them. The main thing in this matter is the design of the room. If the bathroom has been modernly renovated and plumbing fixtures with taps and flush buttons made of chromed metal have been installed, then the unsightly appearance of the plastic product will spoil the whole picture.

Better pick up metal siphon to match the mixer on the sink - with a classic steel sheen, gold or bronze. It will look aesthetically pleasing and retain its appearance for a long time.

At the same time, installing a plastic device under the sink will avoid regular cleaning of lime deposits that will constantly settle on the metal.

When choosing a design, you need to pay attention to the following:

What type of washbasin will be in the bathroom. If it is with a pedestal or cabinet, then the type of siphon does not play any role. But if the drain device will be under the sink in the open state, then it is better to take care of its design.

Be sure to make sure that the sink has a neck of the same diameter as the siphon.
If you plan to put a washing machine in the room, then you need to take care of the pipe for connecting it to the sewer.
If a pipe siphon is taken for a bathroom sink, then careful measurement and calculation of all distances will be required.
The diameter of the sewer inlet is usually standard on all products, but there are exceptions in the case of purchasing a foreign-made sample. Therefore, before purchasing, it is better to compare the diameters.

When choosing, you can give preference to any model of the device, since there is nothing complicated in their structure and therefore there is no fundamental difference, except for the price.

Installation of different types of siphons

Installing or replacing a sink siphon is not difficult even for beginners. Of the tools and materials, in addition to the culprit of the work, the following are required:

Silicone sealant.
Rubber coupling-adapter.
Sealing tape.
Phillips screwdriver.

The surface of the sink and gasket must be degreased with any detergent that is used for dishes so that their surfaces get closer contact and there are no smudges in the future.

Mounting order:

Put a gasket on the hole in the sink.
Insert the drain socket.
From below, under the sink, we put on the second rubber gasket on the socket.
We connect the entire structure with a plastic nut.

The second mounting option is designed for other designs:

I put a gasket in the sink.
Place a metal grill on top.
Insert the included long screw into it.
We bring the siphon from below, and connect the structure with a screw.

There are other, more complex designs, but their installation requires some experience and skill.

Before buying a siphon, you need to make sure that its throughput will correspond to the amount of water drained. Therefore, a siphon with a small section is not suitable for every sink.

We completed a major renovation in the bathroom over a month ago, and since we have a combined bathroom, all the plumbing was changed at once. The siphon was chosen the longest so that it would not clog quickly, the fact is that I have long hair, so it was constantly clogged, despite the fact that I cleaned the drain, the water barely passed. Now everything is fine with this, but after replacing the siphon, a terrible smell appeared, it is impossible to leave the door to the bathroom open. The workers said that everything was installed correctly. Is it possible to smell in the bathroom due to an incorrectly connected siphon? If it's not about him, then what is? Can't stand this stench.

  Alina, hello!
  Yes, a siphon can cause an unpleasant smell from the sewer. A siphon can pass water well, but not have a water seal, which serves as an obstacle to bad odors.
  Checking for a water seal is very simple, plug the drains in the sink and tub with polyethylene or plugs, and plug or tape overflow holes in the tub and sink.
  You will feel the difference in just a few minutes! If the smells are gone, then the problem is in the siphons. In turn, open the drain and overflow in the bath, and then in the sink, and you will find out exactly where the siphon is not correctly assembled.
  If the smell still remains with the sealed holes, look for cracks and holes in the sewer pipes and junctions to the siphons. And also pay attention to ventilation, the smell can come from there.
  I wish to overcome this problem! 🙂

I have a corrugation, because the sink rests on the cabinet, and there is not enough space. But the bottle siphon is much more convenient: if it gets clogged, it is easy to unwind and clean it, and the corrugation must be removed entirely.

Answer
Alexander

I remember once there was a problem with the siphon, water did not drain well, but they came up with a wonderful device: the “mole”. You put it in the sink and it cleans it out. I just have a siphon located in such a way that it is quite difficult to get to it. For those in whom it is located adequately enough, you can also clean it manually (at your own peril and risk). As for the choice of a siphon, yes, metal is better (much more reliable) and no matter what kind of metal, it’s already looking at what the view will be like against the background of the kitchen.

I decided to make repairs in the apartment, I quickly decided on the design of the rooms and the kitchen, but I did not like the design projects of the bathroom at all. I wanted something unusual, with modern plumbing and mirrors. After much deliberation, the project was approved, but faced with the following problem: the color of the siphon stood out from the overall color scheme. Having traveled around four stores, I found the brass siphon I needed. Yes, it turned out more expensive than plastic, but it harmoniously fit into the bathroom.

Answer
Lida

I never thought about the appearance of the siphon, since there are cabinets in the bathroom and in the kitchen. Wow, how stylish they are made) It seems to me that this is an excess for the rich, and the siphon has a purely practical function and its appearance is not important.

Answer

Debriefing is of course normal, but over time, no siphons help to avoid blockages. Therefore, the most optimal option is still corrugated siphons. They are not particularly aesthetic and durable, but due to their low cost, it is not a pity to throw them away and replace them with new ones! Especially in the bathroom, if there are a lot of women in the house, not a single siphon normally copes with hair getting into the water!

Answer

There was somehow a problem with the siphon about 5 years ago.Clogged literally every 2-3 days. Moreover, apart from water, almost did not pass through it, he simply did not understand why this was happening. No cleansers helped for a long time. I learned about the corrugated siphon, I decided to install it right away. Problems have been removed as if by hand, for all these 5 years I have been cleaning every 3 months, and everything works as it should.

There are three women in our family, and a lot of hair falls into the sink and tub all the time. The gratings on the drain holes do not cope, blockages occur periodically. Now we have corrugated siphons, and the hair inside catches on the walls and gradually accumulates. I’m thinking about changing the siphon, so the information in the article is very handy, I’ll take a closer look at pipe-type plastic siphons.

A rather detailed article from which I learned for myself at least how to cope with the smell from the siphon in the kitchen. After all, this is really a problem, it gets clogged up pretty quickly, but cleaning it daily is simply not possible. And here for the first time I heard about a dry siphon, which, thanks to a special closing membrane, leaves unpleasant odors inside and they do not disperse throughout the kitchen. Already installed and convinced of this on personal experience.

Answer
Sergei

For the bathroom, you can take a siphon without a glass, there is no such dirt as in the kitchen, so the usual knee option is suitable, it is cheaper, as a rule. You can install it yourself, just follow the instructions.
