How to assemble the sink siphon in the kitchen
A siphon is installed under the sink to ensure quick drainage of dirty water into the sewer system. Replacing and installing this device for some may be challenging. This review will discuss how to collect the siphon in the kitchen. In order to complete the installation, the right approach is needed, and then even a non-professional will do the job. To do this, do not need a specific tool, you need only a screwdriver.
Device and Purpose
Siphon not only removes dirty water, but it has another purpose. Due to the special design, large debris is retained in it, therefore its ingress into the sewer pipe is prevented and therefore the likelihood of clogging is reduced. But the main function of this device is the formation of a water seal, which serves to protect the room from harmful and unpleasant odors.
Particularly noteworthy is that for the bathroom it is advisable to use a siphon, having the appearance of a pipe with a special S-or U-shaped bend to form a water plug. For kitchen sink, it has a more complex structure, since it is mainly intended for the accumulation of garbage, followed by cleaning.
Sink siphons in the kitchen have the following device:
- Pipe connection for washing. The design with the help of a nut is fixed to the lattice filter of the sink.
- Pipe connection for overflow. It is used in cases when it is possible to connect the drain of a washing machine or dishwasher.
- The tank or glass is the main part of the design. A water lock is formed inside the tank, and due to the volumetric cover it is possible to quickly remove the accumulated debris.
- The branch pipe is intended for connection to a sewer pipe for the purpose of removal of dirty water.
Equipment
Above is a diagram showing the location of parts. But whatever the design of the siphon, each of them has a small knee or a small reservoir, due to which some of the water is retained in the pipe. This forms a water trap, which prevents noise and unpleasant odors from entering the room.
For the manufacture of this device is used most often plastic (propylene, polyethylene, PVC) or chrome-plated metal. The product of metal, in addition to being distinguished by reliability, also looks more attractive and solid. But over time, the oxidation of the metal occurs, even despite the electroplating. For this reason, in everyday life, it will be preferable to use plastic devices that are non-corrosive and easily cleaned from dirt, and more affordable.
Equipment пластикового сифона:
- Pipe connection to the sink. With the help of a nut, the device is fixed to the washing filter grill.
- Branch pipe outlet. It is connected to the sewer pipe in order to drain dirty water.
- The glass or tank is the main part of the design. A water seal is formed in the glass. Below is a cover that is designed to quickly remove accumulated debris.
- Exhaust pipe. In some models, a drain is added, through which the connection of a washing machine or dishwasher is performed.
- The protective grating, which is installed in the drain hole of the sink, does not allow large waste into the sewer system.
- Rubber stopper designed to plug the drain hole. In cheap devices such a cork is not provided.
- Rubber gasket for placement between the outlet and the sink. The thickness of the gasket can be 3-5 mm.
- Rubber gasket under the exhaust pipe.
- Nut made of plastic exhaust pipe.
- Connecting screw of copper or stainless steel Ø 6–8 mm. It is noteworthy that cheap models come with metal screws with a thin coating of nickel or chrome. Screws from such material are unreliable, quickly rust and collapse. Choose a device with a quality magnet, you can use a small magnet, which is checked metal. Stainless steel screws will not magnet.
- Brass, copper or stainless steel nut. In this case, the iron nut will not work, since due to corrosion it will not last even more than a year.
- Body products in the form of a knee or bottle.
- Plastic coupling nut.
- Two tapered rubber or plastic gaskets.
- Sewer drainage.
- Nut for fastening the plastic adapter.
- The siphon cup or lid is for durability.
- Rubber large gasket for a snug fit of the instrument cover to the body.
- Sewer drain - standard plastic or corrugated pipe, plastic pipe, flexible hose.
There may also be a siphon with overflow, which is installed on sinks, in the construction of which a overflow is provided.
The bottle-type device, despite the more complex design, is more popular in everyday life than the pipe siphon, as it is compact and easy to maintain. And if valuable items accidentally fall into the sink, they can be easily removed by unscrewing the bottom cover.
Assembly
Installation of the siphon can make every owner of the house But although the assembly and installation of the device is relatively simple, however, this process requires a responsible approach. Otherwise, a negligent attitude will lead to leakage and the appearance of unpleasant odors from the drain hole in the room.
When buying you need to make sure that the rubber pads are of good quality. In the presence of the seller, the assembled device is disassembled to make sure that the fastenings are secure and all the components are in stock. Do not ignore possible defects (chips, cracks, burrs), as they can contribute to leaks.
Choosing a kitchen siphon, you should pay attention to some points:
- The diameter of the hole in the sink should coincide with the diameter of the filter grid that comes with the device.
- Connecting other plumbing fixtures. If you need to connect a washing machine or dishwasher that requires water drainage to the sewer pipe, you should purchase a device with an additional outlet for connecting the drain hose.
- The dimensions of the product for installation under the sink need free space. Otherwise, you must purchase a small device.
- The diameter of the sewer hole. The pipe that serves as the connection of the outlet pipe and the sewage system must be of the appropriate diameter. In the case of a smaller diameter, a rubber adapter may be required, but the diameter should not be larger than the sewer.
- Aesthetic solution. If the device is externally closed or hidden in a kitchen cabinet, it does not matter what material it is made of. And for an open location, it would be appropriate to purchase a chrome-plated product, although its cost is more expensive.
- The cost of the product. Not always the quality of the device depends on its cost. It is quite natural that it is possible to operate a metal siphon in the kitchen much longer than plastic. But, in principle, a plastic product can serve a very long time. Therefore, the difference in price is due to the external component, rather than functionality.
Basic assembly recommendations
As a rule, complete with the device attached instructions for assembling the product. But even if it is absent, it is possible to mount it without special difficulties. The following tips will help:
- It is best to assemble the siphon for kitchen sink by hand, without using a screwdriver (instead of a screwdriver). This will allow you to control the clamping force, so as not to break the integrity of the connections on the thread.
- Before you tighten the parts, install rubber gaskets in place. For reliable sealing, you can use sanitary sealant.
- The height of the nozzle connecting the sink and the glass can be adjusted. When changing the position of the gasket seal set the optimum height of the device.
- Nuts must be tightened, but do not overdo it, otherwise you can disrupt the thread.
- When all parts are connected, remove excess sealant (if used). A visual check of the build quality is required.
Installation process
- Before you install a sink drain, you must perform the preparatory work. In case of connection with the old cast-iron pipe, the latter is cleaned of dirt and a rubber gasket is installed. With a plastic pipe, the tip is brought to the desired level (maximum 40 cm from the floor level). After that, an adapter is installed on the tip.
- Next is the dismantling of old equipment. The screw is unscrewed with a screwdriver.
- The next step is to thoroughly clean the seat of rust, dirt and grease.
- Now the siphon is installed and fixed with a screw by a mixer with a trap.
- It is necessary to connect the main part of the appliance with the pipe under the sink.
- In some cases, you can connect appliances (dishwasher or washing machine). But it is better to connect with the sewage system and perform a primary check. During the test, bends must be closed with plugs.
- If during the check there were no leaks, then you can connect additional equipment. For reliability, the drain hoses for the dishwasher and washing machine are secured with hose clamps. Make sure that the water drain hose is not bent or twisted, and that water flows freely through it.
Features of attachment to the sink
In the event that the sink has been used and a siphon needs to be replaced with a new one, the old device is dismantled, followed by cleaning the surface of the sink from dirt and debris at the attachment points.
It is important to remember that when installing the device you will need to disconnect it from the sewer pipe. To avoid the spread of unpleasant odors, you must close the sewer opening with a damp cloth that will serve as a temporary stopper for a kitchen sink. You can also wear a plastic bag over the pipe and wrap it with a rope.
Siphons are sold complete with a filter grill, which is first attached to the sink using a mounting bolt (in older models, this part is pressed with a nut from the bottom), and then the fixture is mounted.
Connection to sewage
Proper connection of the siphon under the sink consists in connecting the outlet pipe and the main sewage system using a corrugated pipe. Flexible drainage ensures the connection of the device, regardless of the location of the sewer. If the hole has a large diameter, then use an additional rubber gasket or plastic adapter. The main thing is to drain tightly connected to the sewer pipe.
At the end of the installation, water should be poured into the sink to check how tight all connections are. If there are no water leaks under the sink, the work is considered completed.
Thus, in order to install or replace a siphon, it is not necessary to be an expert. It is enough to choose the right device and follow the technical recommendations. And then this is not a complicated device for a long time.
