Siphon for the kitchen sink: the right choice and installation without mistakes

Tags:Plumbing, With your own hands

Individual parts of plumbing systems are exposed to heavy loads and fail during operation. Sometimes a careless manufacturer is to blame. In other cases - natural wear and tear, or improper user actions. Be that as it may, but accidents must be eliminated as soon as possible. If you know how the siphon works for sinks in the kitchen, then you can do it yourself. To do this, you will need information about the specifics of performing work operations and how to select a new node without errors.

After studying the technology, installing a siphon will not cause difficulties.

Principles of operation and design features

When draining liquids together with waste into the sewer, it is necessary to ensure their free movement. At the same time, unpleasant odors should be prevented from entering the room atmosphere.

What functions does a sink siphon perform in the kitchen

Mechanical devices are not suitable for solving the above problem. With their help, it is too difficult to ensure perfect tightness, shutter speed. The exact name of the inventor is unknown. But in this case, it is appropriate to recall the saying that "all ingenious is simple."

Water seal

Normally, the liquid levels in the parts indicated by the arrows are the same. When draining, water fills the container (1). Under the influence of the increased weight, it moves further along the pipeline to the next equilibrium state of levels. From area (2), the liquid, together with impurities, enters the sewer.

For example, a specialized technological product is used. But the kitchen sink siphon works on the same principles. A hydraulic seal is a pipe turn. It fulfills its purpose reliably, over a long period of operation. It is only necessary to ensure that there are no blockages and monitor the integrity of the drain system.

Siphon device for kitchen sinks

For a sanitary plug, only one 180 ° bend is sufficient. To prevent blockages, the pipe diameter is increased.

Typical siphon

To eliminate some of the shortcomings, changes were made to the classical design.

Disassembled siphon

Using this picture, you can study in detail the individual parts of the product:

The unit for connecting to the sink is supplemented with a removable mesh. It acts as a mechanical pre-filter, does not let large debris through. When pressed, it hermetically closes the inlet neck.
This is a siphon for a kitchen sink with a large mouth. Its dimensions are sufficient for connecting an overflow pipe. This solution prevents the sink from overflowing with water.
A bend was made in the next section. It is used to connect the drain of the drinking filter, other equipment.

If there are several taps, a washing machine and a dishwasher can be connected to the drain

The lower part should be studied more closely. Here, a “bottle” type seal is used. It has a twist-off siphon. Here dirt accumulates, which, if necessary, will be quickly removed.

Differences between different models and selection rules

The design differences are discussed above. The following information will help you more accurately select the composition of the equipment:

The cheapest are plastic models. Their only drawback is their relatively low mechanical strength. They weigh little and are not subject to the destructive effects of corrosion processes. Modern production technologies ensure that there are no irregularities on the internal surfaces and at the joints.

Plastic siphon connection

The metal product is stronger. But with the correct installation and operation of the sink siphon, excessive mechanical stress will not occur in the kitchen. But it should be noted the increased durability of threaded connections.

Such a product will be a real interior decoration.

For a complex transition to the central sewerage, a flexible pipe is useful.

Metal "corrugation"

A plastic analog is suitable for solving many practical problems.
To eliminate the cause of blockages, a special device is installed directly in front of the siphon.

Electromechanical shredder

The exact configuration of the drainage system is selected taking into account the characteristics of a particular project.

How to assemble a kitchen sink siphon

When all the components of this part of the drainage system have been acquired, the following installation algorithm is applied:

The place of work is vacated. If necessary, dismantle the cabinet furniture doors.
Install a sink drinking filters and other equipment. Holes for drain hoses are made in the walls of the furniture.

The sink is installed before connecting the drainage system.

The siphon is collected in the direction from the sink to the central sewer. When connecting the parts, take into account the correct position of the O-rings recommended by the manufacturer.Limit forces so as not to damage threaded connections.
Cut the pipes using a hacksaw.

For plastic, a canvas on wood will be enough

For plastic there will be enough canvas "on wood"

After complete assembly of the structure, check the tightness of the joints with test drains.
The removed cabinet doors are reinstalled.

Additional tips and tricks for maintenance

Use the following information to rule out incorrect decisions:

In the shopping list, include not only the constituent parts of the siphon, but also the necessary consumables and tools.

It is necessary to check whether everything is at home to perform work operations

Various modifications are used to solve special problems. The flat sink siphon is installed to save space.

Flat design will save significant space under the sink

Plugs, protective pads, and other functional devices simplify operation and expand basic capabilities.
When installing flexible pipes, it is necessary to exclude kinks that impede the movement of liquid. A route is created that prevents contact with vibrating, overheated equipment or other parts that could damage plastic parts.
When comparing different models of siphons for kitchen sinks, the price must be taken into account in conjunction with the durability.
Blockages are formed with a small diameter of the main sewer pipes, insufficient slope. If unpleasant situations arise often, and the elimination of structural defects is impossible, you will have to buy a specialized device.

A modern shredder performs its functions in automatic mode

Conclusion

Before buying a new product, it is necessary to clarify the features of its operation and placement:

If the siphon is equipped with a pipe, it can be used to connect new kitchen equipment. When inoperative, the branch is closed with a sealed stopper.
To prevent accidental overflow of water, buy a model equipped accordingly.
When placed in a closed box, it makes no sense to purchase an expensive product with outstanding aesthetic characteristics.
Installation of equipment is carried out according to the above instructions with a mandatory performance check.

Using the above tips in practice will prevent mistakes and help you install new plumbing fixtures without assistance.
