Even a novice who does such work for the first time can install a sink siphon in the kitchen. The designs of modern drain systems are designed for manual assembly. Only in the most rare cases, a special set of tools may be required to implement the task. Usually everything is limited to the use of pliers and a screwdriver.
What is a siphon?
Such plumbing structures in most cases are represented by a plastic or metal pipe, less often by several pipes of a specific, curved shape. Serves as a device for the removal of dirty, waste water, small sewage into the sewer. Due to the presence of a slight bend, the siphon for the sink in the kitchen leaves a small proportion of water in the pipe, which forms a kind of sump. The latter prevents the penetration of sewer noise, gases, and unpleasant odors back into the room.
Siphon diagram for kitchen sink
Toto get a clear idea of \u200b\u200bassembling and installing a siphon, let's look at its standard scheme. Plumbing fixtures are completed with items such as:
- Knee or bottle-shaped body.
- Outlet.
- Drain pipe.
- Cuff.
- Plastic nuts.
- Insulating pads.
- Rubber plugs (bottom and top).
- Tie screw.
- Decorative cover for the sink.
Materials of production
Modern sink siphons with overflow for the kitchen are made mainly of PVC, chrome-plated brass or propylene. The most expensive are metal products. However, due to the relatively high price, their purchase looks really justified only in terms of prestige and aesthetic appearance. From the point of view of practicality, durability and ease of use, plastic siphons for kitchen sinks with overflow are not inferior to the same metal ones.
PVC construction is the cheapest option. Even with daily use, such a siphon will last at least 7-10 years.
As for propylene products, they are 15-20% more expensive than PVC counterparts. With a quality installation, such a siphon for a sink in the kitchen will last for decades. Unlike chrome designs, chemically resistant, durable propylene can be cleaned with a metal cable or hook.
Drain pipe
The siphon device for the sink in the kitchen suggests the possibility of installing a corrugated or rigid drain pipe. It is better to give preference to the latter option, since fine waste and pollution intensively accumulate on the internal grooves of the corrugations. In addition, a rigid pipe is much more difficult to accidentally damage objects that are under the sink.
Sealant
To install a kitchen sink siphon, you will need a semi-liquid or plastic sealant. The best choice in most cases can be an inexpensive silicone tool.
Before giving preference to one or another sealant, it is necessary to check it for acidity. You can determine how chemically neutral a substance is by squeezing a small amount of it out of the container and smelling it. If there is a pungent vinegar smell, then the sealant is not very suitable for such work.
On sale there are means for insulating connecting seams based on natural rubber. These sealants are expensive. However, their service life is at least several decades.
Connection settings
Standard connector sizes are 32, 40 and 50 mm in diameter. When choosing a siphon for washing in the kitchen, you need to decide on the parameters of the old design. If you cannot find a product of the required size, you must resort to buying a special adapter cuff.
Today, there are siphons on sale that have a stepped end of the spout. The latter can be adaptedfor all pipe sizes. All you need to do is carefully cut off the excess material and purchase a suitable sealant.
How to assemble a kitchen sink siphon?
The assembly of the structure is based on the attached instructions with the product diagram. When performing the recommended actions in a clear sequence, even a beginner should not have problems with the layout of the elements of the drain system. However, in order to avoid leaks, you need to pay attention to several important nuances:
- In the assembly process, the main thing is to create the most tight connections. Even before buying, the product should be inspected for defects. Particular attention must be paid to the quality of the thread.
- During the installation of connections, the gaskets should be securely fixed. For these purposes, a sealant is used. Screwing the knees of the drain system is done until it stops.
- It should be borne in mind that several spacers are used to arrange the installation area of the decorative trim. Black is used for laying on the top of the nozzle. Thinner - white, fits under the overlay.
- Once the kitchen sink siphon is fully assembled, it is recommended to get rid of excess sealant that protrudes from the edges of the joints.
Preparation for installation
Having figured out how to assemble a siphon in the kitchen, you can proceed to dismantle the old structure and clean the surfaces of the sewer pipe. Implementing the task, one should not attach too much importance to the presenceresidual dirt on the surface of the drain, since the special sealing collar is designed to fit on a rough base.
Certain difficulties may arise when replacing a Soviet cast-iron siphon embedded in a pipe with a cement fit. In this case, you will have to work hard to depressurize the connection using a hammer, chisel or chisel. This is required to remove the old cement from the pipe and dismantle the old siphon.
When preparing a siphon for a double sink in the kitchen or a single tank, you need to make sure that fragments of brittle cast iron and particles of cement do not remain in the sewer pipe. During the operation of the new system, such debris can turn into a source of regular blockages. It is convenient to remove all kinds of debris from the sewer branch with pliers and tweezers.
Installation
How to install a siphon in the kitchen? For reliable installation, work must be carried out in strict sequence:
- The mounting collar, pre-lubricated with sealant, is placed in the sewer pipe. All surfaces must be dry.
- The mating (end) surfaces of body threaded connections are checked. If necessary, burrs can be carefully cut off with a sharp blade, as their presence can damage the gaskets.
- The end of the drain pipe is inserted into the cuff and securely fastened. If you have to work with a fastener in the form of a clamp, you will have to usescrewdriver.
- The drain grate is mounted in the sink. The black bottom gasket is not installed yet.
- A thin ring gasket is placed in the groove of the plug, which is abundantly lubricated with sealant. Next, the cork is wrapped. It is enough to capture the thread at a distance of about 2-3 of its turns.
- If the body of the siphon is represented by a pipe in the form of a bottle, a special valve with a damper opening outward is placed in it. The structure is attached to the exhaust pipe.
- The lower drain gasket is placed in the groove of the upper pipe, the siphon housing nut is screwed in.
- Slightly rocking the knee of the structure, you should carefully alternately tighten the side and top nuts of the bottle.
Check for performance
When all the activities aimed at assembling and installing the siphon are completed, it is worth starting to test the drain system. To do this, water is supplied to the sink under maximum pressure, which allows you to test the tightness of the joints. The absence of leaks indicates the correct performance of the work.
Helpful tips
When choosing siphons for Blanco sinks for the kitchen or considering any other product as a suitable option, it is worth once again checking the system for the presence of all structural components. Unopened packages often do not contain enough fasteners needed for a successful installation.
When assembling and installing the siphon, all parts must be clean and dry. One of the mainthe causes of leaks are the ingress of dirt and sand on the rubber gaskets.
The siphon must be installed in such a way that its outlet is an order of magnitude higher than the inlet of the sewer drain pipe. Compliance with this requirement allows you to form a certain slope, which becomes a favorable basis for the formation of a free flow of water.
Operation and maintenance
Proper installation of a kitchen sink siphon is an extremely important task. However, good maintenance of the drain system is also important. Timely cleaning contributes to the longest possible operation of the structure.
For the dissolution of deposits in the form of fat masses, the use of caustic soda is recommended. Improves the throughput of the system by periodic, prolonged flushing of pipe connections under the pressure of hot water. In the event of significant blockages, it is worth using special chemicals to clean sewer pipes.
The easiest way to eliminate plugs in the siphon connections is to use a conventional plunger. If, after several movements, the garbage does not pass through the sewer, it is worth disassembling the structure and flushing its individual elements. If there is a plastic siphon, you can get rid of the blockage using a metal wire with a slight thickening at the end. Similar pipe cleaning methods are widely used by plumbers.
If there is a strong smell of sewerage in the kitchen or inthe siphon structure has a leak, it is worth doing an independent repair of the system or resorting to the help of craftsmen. In this case, one should not forget about the need to remove the old sealant and apply a new one.
In closing
The siphon is an important plumbing tool in both the kitchen and the bathroom. Therefore, it is desirable that any actions that we described above in the article be performed by trained specialists, which will serve as a guarantee of reliable and durable operation of the system. However, if you have some experience or in case of emergency, you should use the above recommendations for doing the work yourself.
