Purpose of the siphon
It would seem that the question that is obvious to a knowledgeable person and does not require an answer as to why installing a siphon under the sink into the kitchen actually baffles many. Often you can hear the answer to it - it’s just that way, but why it’s necessary, no one answers. We need this item is not easy in order to connect the sink with sewage, and in order to further prevent the passage of large particles of debris from the sink into the sewer, and the unpleasant smell back out of it.

The kitchen sink siphon is usually different for different manufacturers, but the principle of operation is always the same. The structure of the valve may include several elements:
- Collapsible siphon;
- Several fittings to connect to the sewer system;
- Gaskets and seals for fittings;
- Corrugated or smooth tubes;
- Guide funnel;
- Nets and catchers;
- Gaskets, seals and hardware for attaching the structure to the sink.
Complete siphon with overflow
Significantly different from the specified list is the siphon for double sinks in the kitchen. Despite the fact that the structural elements of it will be the same, their number will be almost twice as large. Without his instructions, accordingly, it will be harder to assemble. But at the same time, having collected half the design, you can be confident in the successful implementation of the task.

It is also worth noting that the design is somewhat more complicated when a siphon is selected for the kitchen sink with overflow. It adds a special overflow tube, usually made of corrugated plastic, auxiliary fittings and gasket mounts. In this case, gaskets are installed not only on the fitting connecting the siphon with the overflow, but also between the hole in the sink and the adapter of the overflow hose.
Brief instructions for collecting siphon with overflow
The design is further complicated if the siphon is quite expensive and has an automated system for delaying and draining water in the sink. In this case, he can complete the mechanical button, which with the help of a special connection sets in motion a spring associated with the structure located inside the funnel. This design moves and controls the drain valve when the button is operated. For the button itself, in this case, a special place may be provided at the sink, usually hidden by a plug.
Simple plastic siphon in the kitchen under the sink
Before you assemble the siphon for the sink in the kitchen, make sure that all the complete parts are in place and all the necessary tools are in sight. Otherwise, problems with the assembly will be provided. But before starting the siphon assembly, make sure that you do not need to dismantle the old siphon that has failed and requires urgent replacement.
Essential items for siphon collection
If, however, the old siphon is installed, dismantle it carefully so as not to damage the existing plumbing. Otherwise, it will be necessary to change not only the siphon, but also the sink with a tap or mixer, depending on the scale of the domestic disaster.
Before dismantling, install a container under the sink to remove excess stagnant water and other fractions from the old siphon or sink, if there is anything in it before repair begins.
Kitchen double sink with metal siphon
If the old siphon was attached to the sink with a screw, use a screwdriver with the appropriate nozzle, since using a screwdriver of appropriate size is not always effective, because during operation the metal from which the screw is made may be subject to rust or corrosion. They block it inside the construction and do not allow dismantling the siphon.
Tip: Use a cordless screwdriver to avoid short-circuits in the electrical network when working with power tools.
Replacing the siphon task is simple, one requiring a specific tool and understanding of the principle of the device
If the notches of a screw or other fastener fastener holding the net are erased for some reason, cut the net to dismantle the siphon. This element can be sacrificed, but you must act carefully so as not to get hurt. To do this, you can use pliers or scissors for metal. So, it will be necessary to cut the net around the screw head, and then the siphon will instantly separate from the sink. This moment is important not to miss, so as not to stain everything around. Catch the siphon from below and collect the liquid in the already prepared container.
From the surface of the sink, carefully remove the remains of the net, and then wipe the surface of the sink with a cloth to clean it of dirt that could accumulate under the net and rubber lining.
Drain the liquid in the sink will depend on the correct installation of the siphon
Do not forget that the siphon is connected to the sewer. Usually between the connecting tube and the entrance to the sewage there is a sealing gum, providing a tight connection. It may cause difficulty in removing the tube.
If the sink is new and you just need to install a siphon on it, the task becomes much simpler, and you can immediately proceed to the assembly of a new design.
The advantage of plastic siphons - the inability to accumulate debris and non-susceptibility to corrosion
Assembly and installation of a siphon
Upon completion of the preparation, you can proceed directly to the installation of the siphon. Assembly can be started in different ways. The first method involves pre-assembling the base structure and fixing it on the sink. But you can go from the reverse, and gradually collect all the elements together at the sink. Essentially it does not change, but in some cases both options may be uncomfortable for the master plumber, or for you, depending on who is involved in the work.
Irrespective of a type of a hydrolock installation is carried out by the uniform principle
Many recommend to pre-assemble the main part, and then install it directly on the car wash, citing the fact that under it there is not much room for maneuvering hands and tools, and the light is usually completely absent. Therefore, follow the example of the masses and will collect the siphon and fittings in parts.
Tip: To understand the sequence of connecting elements, use the instructions. It is often written not a lot, but there is a compact illustration of the serial connection of parts.
Installation of the structure at the sink
Assembling the main part
The siphon itself is most often the largest component of the kit, consisting of two parts - the body and the removable bowl. It is removed to remove obstruction occurring during operation. At the time of assembly, the opposite is required to connect them. Between them, usually installed the appropriate size complete gasket. Its size should correspond to the diameter of the screw mounting bowl. That is how they are usually connected. A bowl without the use of tools is wound on the base from the bottom.
The main feature of the chrome-plated siphon is durability and strength
At the top of the base there is a drain hole where the funnel is installed. It has a screw notch to which the connecting fitting will be attached. It is put on the funnel so that the notches on it and on the basis coincide.
Brief visual instruction for mounting the siphon to a rectangular and circular sink
Between the fitting and the base is required to install the gasket, and only then connect them. The gasket for the fitting in the kit may not be one, but immediately a pair. If there are 2 of them, then one in the form of a washer (a flat ring with a hole in the center) will be placed inside the fitting, and the second cone-shaped one is installed below, directly on the tubular part of the funnel. The narrow part of the tapered rubber gasket should be directed toward the base of the siphon in order to securely fix the funnel at the desired height. Then the fitting is tightly tightened enough to avoid leaks in the future.

Connection with sink
After the cone is securely fixed on the siphon, it can be mounted on the sink. The pre-assembled structure is placed under the drain hole in the sink. Between them, a rubber or silicone gasket is required, which is necessary to prevent leakage. Its outer diameter must coincide with the diameter of the upper part of the funnel. The assembled structure must be centered again to avoid leakage.
Metal siphon is the most expensive option
On top of the drain hole in the sink is set another pair of elements. This is a grid or grille and its corresponding gasket. Sometimes it is missing, but this is not a problem, since the main function is always performed by the gasket located between the sink and the funnel.
The corresponding complete screw or other hardware is installed in the center of the lattice. When screwing it, parts of the structure are connected, and the stronger the connection, the lower the probability of future leakage.
Siphon is one of the most important parts in a home plumbing system.
Tip: when connecting it is important not to overdo it, and not to tighten the screw. Since in this case it is possible to damage the grille, and it will then have to be replaced as a matter of urgency.
Bottle siphon attached to the kitchen sink
At this connection siphon with sink may not end. Additional operations are required then, the washing model model is equipped with an overflow hole, and in the siphon there is an addition in the form of an overflow tube with an adapter.
The adapter is usually attached to the sink with a screw, and a gasket is also installed between it and the sink. The connection of the tube with the adapter and the siphon occurs using the same fixings that are used to connect the funnel to the siphon.

Connection to sewage
On the side of the base there is another hole on which the connecting pipe for sewage is mounted. The type of tube will depend directly on the type of tube. Smooth tubes are more often prefabricated and its parts are attached to each other with fittings and additional gaskets. In addition, their manufacturer is often made large with a margin of length. Therefore, they often have to be cut with a hacksaw or grinder, after measuring the required length. Do not forget that some tubes can have mutually inserted design, due to which the distance between the connecting nodes can be adjusted.
You can install the siphon in the kitchen with your own hands, it will not be difficult
Corrugated tubes are much easier to install. They rarely have to be cut, and their length can be adjusted with the help of a conventional tube assembly-stretching according to the accordion principle. But when choosing a siphon, you should not forget that such pipes are more often blocked due to their design, especially when used in the kitchen.
The tube is connected to the siphon using a fitting with gaskets according to the principle described above, and its connection to the sewage inlet is carried out using a rubber adapter - a gasket. Most often it is inserted inside the hole, and a connecting tube is installed in its internal diameter.

Tip: To ensure easy insertion of the tube into the adapter, lubricate its base with a thin layer of detergent.
Siphon for the kitchen sink: conclusions
As you already understood, it is not enough just to buy a siphon for a sink in the kitchen. It needs to be installed and it requires some skills. Do not worry that you do not have them, because it is not difficult if the siphon design is simple enough. The sink siphon in the kitchen, the price of which is lower, is always installed faster and with less problems.

But do not forget about the difference in price, and how it is formed. Since low-quality components will also cost less, but at the same time, their service life will be much shorter than that of a more expensive product.
