Sink siphon in the kitchen: types of devices, description, installation

Siphon is one of the most important elements of a domestic water supply system. The design of this device does not allow unpleasant noises and smells from the sewer into the house due to a kind of plug from the water. At the same time, he passes used water into the sewer. The selection and assembly of it is a rather important point, since the durability and reliability of the device will depend on its material, design and other characteristics. For the sink in the kitchen, it can be in various modifications and options, so the choice is very difficult.

Features, types, device siphons

To install the siphon, three main types of these devices are used:

• Corrugated.

The simplest of all types, which is a plastic folded pipe on a curved frame. On the pipe, on one side, there is an elbow through which water flows out of the sink, and on the other, an adapter that connects to the sewer system. This design is the easiest to assemble - no special tools and skills are required for installation. Another advantage is the flexibility of the frame: this device with corrugation can be mounted anywhere. For example, when the sink or washbasin is not standard, there will be no problem connecting this particular type. In addition, it is the cheapest. The disadvantage of this type is the difficulty in cleaning. When this device clogs, an ordinary tube in this case will not be able to help - it is necessary to disassemble the entire structure and spend a lot of time on cleaning;

• Bottle.

The most popular option. The water seal in this case is located in the lower part, which has the shape of a bottle. The advantages and disadvantages of this design are opposite to corrugated. This type of device is more difficult to install and disassemble, but during its use it is easier to clean the blockages. A significant advantage of this type - you can connect additional equipment using splitters or tees. Therefore, bottle constructions for double washing in the kitchen are the best option. A useful feature of this system is the presence of overflow. This structural feature is used to control the water level in the sink. Even when the pipe is clogged, it will not allow water to spill over the edge of the sink;

• Pipe.

Represents a curved rigid pipe, which can be non-separable or collapsible. The disadvantage is that the rigid structure requires the exact combination of the drain into the sewer and the outlet of the sink. Both the overflow and the water lock are located in the pipe structure, so when your sink is installed according to the standard, you can safely put a pipe siphon on it.

The choice of the type of construction will depend on many parameters: your material situation, the location of the sink relative to the sewer outlet and others.

There is also a fourth type of construction - hidden. By and large, this is a bottle siphon, but the bottle is built into the wall. This is the most expensive option, which makes it possible to hide communications and significantly save space. When you have enough money and you decide to boast of good taste, it is best to opt for the hidden type.

Additional knee elements

In addition to the main structure, additional structural elements can be placed on them:

• lateral auxiliary input - they are equipped with models to which various equipment, for example, a washing machine, can be connected. This entrance is most often located between the neck of the sink and the water seal;
• overflow - choose a siphon with overflow for washing in the kitchen is necessary to prevent flooding. Overflow goes directly to the sewer outlet. In the kitchen sink, it is an outer tube.

It is advisable to choose a siphon with both of these functions. This will save you from the possibility of accidental flooding, when, for example, the drain has closed the dishes accumulated in the sink, and it will also allow you to connect equipment such as a washing machine or dishwasher.

Material selection

There are two main materials for their manufacture - metal and plastic. All of them have their disadvantages, advantages and features:

• 
  metal are more expensive, unlike polymer, but they are also the most durable. The most popular materials for metal products are bronze or brass. They differ in that for a long time they resist corrosion and do not oxidize. There are still options for stainless steel structures, but they are not used very often because of their high cost. Chrome plated is the most beautiful, but also the most expensive option;
• plastic - cheaper products, especially when they are made of polyethylene. As a rule, they have a small number of connections and a rather simple pipe device. Polypropylene products are more expensive, which are more durable and durable. In addition, polypropylene is not so sensitive to elevated temperatures, which is why it is advised to choose it when you want to connect a washing machine with a boiling function. In some cases, plastic devices may leak. Sometimes it may be sufficient to tighten the threaded connections.

Features of choice

Before purchasing, you need to consider a number of important features that can help you choose the model you need:

• equipment design. Today, manufacturers offer a wide selection of materials and designs. There are siphons with a built-in cork, an overlay for protection, metal or plastic flasks. An important point during the selection is the number of gaskets and washers. When there will be less of them than necessary for installation, this can cause some inconvenience;
• type of plumbing where the siphon will be connected. It is quite simple to purchase equipment for a standard sink, but if the sink was purchased to order and was not installed according to standards, in this case you will need to suffer. The best option in these situations is a corrugated look, but you can also connect a bottle;
• the presence of overflow. A product with overflow is an additional insurance against flooding of your home;
• volume of water planned to pass. This is quite an important parameter, since large pipes will require large cross-sections for significant runoff. Otherwise, you risk often getting minor, but rather unpleasant floods in the kitchen;
• price of equipment. Devices with an overflow of metal or plastic can vary significantly in cost, so during the selection you need to focus on your financial capabilities;
• the diameter of the drain hole in the sewer and the neck of the sink, the distance between these holes. When these parameters differ from the standard, you will need to buy additional adapters.

Naturally, you can always buy products easier and cheaper, but in this case, most likely, after a certain time it will need to be replaced. And this is not only a big time expense, but also considerable financial expenses. Therefore, it is advisable to take into account all the possibilities in advance, for example, additional connection of equipment.

Maintenance and installation

It’s not so difficult to assemble a siphon for kitchen sinks with overflow or other design features with your own hands. Naturally, in this case, a certain set of tools and small skills in the field of work with plumbing are required. When all this is available, you can remove it and put in a new one without significant effort. Tools include a hacksaw, screwdriver, sandpaper and tape measure.

Dismantling

Before installing a new device, you must remove the old one. This is quite simple: with a screwdriver, the screw in the middle of the grate of the drain hole is loosened. Then it is quite simply removed.

Recommendation: Often, after a while, the screw and nut stick together so tightly that it becomes quite difficult to unscrew the siphon. In this case, sometimes you just need to disconnect the lower part of the product and scroll the pipe. When this is not enough, you must use special solvents.

How to assemble: instruction

Before collecting the siphon, you need to lay out all the details in front of you and make sure that all the pipes, gaskets, joints and other elements are enough. Then you can start collecting. Next, we consider the installation of a plastic bottle model, since it is the most popular design for washing in the kitchen.

First you need to take the flat, largest gasket and put it on the largest hole of the drain device. The cap-cap is mounted on top. After that, a nut is thrown onto the nozzle, which is fixed to the sink, where you need to tighten the cone gasket. The nozzle is installed in the upper part of the siphon and screwed on.

After the corrugated pipe is wound. A cap nut is put on it, then you need to pull the cone gasket, and then the corrugation is twisted to the siphon.

Assembly and installation on a sink

Siphons for washing in the kitchen or in the bathroom are placed the same way. First, a grooved sealing ring is placed on the pipe upwards with strips, then the remaining ring is pulled under the metal grill. Then the product is placed under the sink, the drain grate is placed on top, the screw is installed and screwed. Installation is complete. It is only necessary to connect the outlet of the device to the sewer.

Connecting it to the sewers is pretty easy. When the pipe diameter does not match the size of the drain hole, special adapters must be installed. They can be purchased at a specialty store. Instead of a corrugation, a rigid outlet is required to drain the sewer.

After connecting to all drains, the operation of the product must be checked. Why is it filled with water so that a water lock appears. When nothing leaks anywhere, everything is done correctly, the design can be used.

Recommendation: The connections in the plastic siphon must be screwed on tightly, but not very, otherwise you risk damaging the gaskets and threads.

Siphons with overflow or for a sink under the washer are placed in the same way, except that the overflow must be collected separately. The principle of connecting the pipe to the overflow is the same as the corrugations - we put on the nut, then the gasket, install the overflow in the branch, screw the nut.

Care

The purchase of a sink siphon for the kitchen, regardless of the material, type of construction, or other features, means that you will need to periodically clean and clean it. You can increase the interval between cleanings by carefully operating the sink, food chopper or special drain grill. But, one way or another, it will need to be cleaned.

First of all, cleaning the sink siphon will depend on its design. A corrugated product can only be cleaned when it is completely disassembled, but the bottle type of the product is punched with a special tube. Chemicals are also very popular, but they must be selected very carefully, especially when it is plastic. In siphons with a large neck, you can use punching special brushes, and no one canceled the good old plunger.

When you have an old house with decrepit plumbing, it is advisable to immediately replace all the siphons that are in it. It will not take much effort and time, but it will save you from possible problems with sewage and drainage. The simplest, which is made of plastic, it is quite inexpensive, quickly put with minimal skills and a set of tools, eliminates a number of troubles and is easy to operation.
