A sink siphon is quite a simple device, but at the same time extremely important. So much so that if chosen incorrectly, it may not serve as we expected. Knowing these problems, we have prepared a guide for you that will dispel any doubts related to the choice of a siphon for the sink.

Which siphon is suitable for the kitchen sink and which one for the bathroom?
The siphon is an essential element of the hydraulic structure, installed in the drain of the sewage stack. Its main task is to remove sewage, which reduces various unpleasant odors coming from the sewage system. It creates a kind of water seal, separating the air from the drain from the air in the room. The issue of proper water drainage is therefore extremely crucial, because the sewage system emits not only unpleasant odors, but also odors that may be harmful to health. So regardless of whether it is a drain in a kitchen sink or a bathroom washbasin - we must always remember to use an appropriate siphon.
However, as it turns out, siphons in rooms such as the kitchen or bathroom must be properly selected, taking into account the specificity of these places. In the kitchen, due to the presence of food remains, but also fat and other substances, the siphon material must be more durable and resistant to cleaning chemicals.
It is no accident that siphons made of plastic or metal are very popular. They are easy to keep clean and are highly resistant to corrosion. This siphon model also usually has a larger cross-section, which prevents the drain from clogging. A flexible siphon for the sink also works great.
How to choose a siphon for the bathroom? In this room, siphons must adapt to various shapes and sizes of fittings, which is why rubber models are the most popular. Another popular siphon is the plastic model. Both can be adapted quite easily to different configurations. It is worth remembering that the product does not have to be made of high-strength materials, because the drain does not contain the same contaminants as in the kitchen.
How to choose a siphon for a two-bowl sink?
Now let's consider which siphon to choose for the sink, taking into account its structure. There are two types of siphons to choose from. One of them is the bottle siphon, whose characteristic feature is its compact structure. Often chosen for the sink, quite high, but unfortunately also narrow, so they require periodic cleaning. Another type is the U-type siphon (so-called tubular). It also has the advantage that, although it is true, they clog less often, but when this happens, it often has to be dismantled. In this case, the sink does not have a siphon, so it cannot be used.
So, as we can see, the sink siphon can be bottle or pipe, but which one is better suited to a two-bowl sink? When purchasing such a model, we should know the spacing of the drains. On the one hand, nothing will happen if it is not perfectly matched, because the pipes can be cut (according to the instructions), on the other hand, the drains cannot be spaced too far from each other, because there is a risk that the siphon purchased for a two-compartment sink will have to be return it to the store and exchange it for another model.
It is worth remembering that a sink with widely spaced drains requires a special siphon. As for the siphon for a single-bowl sink , there is no such problem because it has one drain and overflow. So we just need to remember about the diameter of the drain and the location of the overflow. Another important aspect concerns the sink compartments, namely whether they are on one level. There are sinks with this position, but also others with a difference in levels. In this situation, you need a siphon that can adjust the height of the sink chambers.
Does every siphon fit every sink?
As we have already mentioned, there are different types of sinks available - single-bowl sink and double-bowl sink. Another division concerns the material of its manufacture. And here the most popular is the steel sink, usually made of stainless and enameled steel, but also made of granite composites and ceramics. However, in this paragraph, in the topic related to the sink, we are interested in a specific issue - are all siphons universal, suitable for any sink? The answer is no, because although all elements have standardized dimensions, they are not identical. The differences mainly concern the diameters of individual elements of the siphon, especially the connection to the sink and the pipe leading to the sewage system. As if that were not enough, it is worth remembering that siphons come in different sizes and shapes, which most often determines whether a given model will work in a specific application.
Is a bottle or pipe siphon better for the sink?
It is impossible to answer this question unequivocally, because everything depends on possibilities and needs. Nevertheless, the bottle siphon is the most popular, mainly because it takes up little space under the washbasin. Therefore, it is a very practical solution. It has a vertical structure, and the name comes from its bottle-like shape. In its lower part there is room for water. Of course, you can clean it yourself. To do this, simply unscrew its lower part and remove the dirt collected there.
The tubular siphon, also known as self-cleaning, will work well in larger bathrooms because its dimensions are larger, although the structure itself is simple and takes the shape of a bent tube.
Regardless of which siphon we choose, it is worth knowing that it can be with or without an overflow. It is a special hole in the sink chamber, which is particularly important when water overflows outside the sink. Thanks to the overflow, nothing like this will happen, because the main drain will be blocked.
It is also worth paying attention to whether the siphon you want to buy is equipped with additional functions, for example an automatic plug. The plug mechanism allows automatic opening and closing of the drain using a special knob. An automatic siphon with a stopper is therefore a good option. So if we want our siphon to be more functional, let's check if it has a stopper. We can say the same about other accessories, such as a strainer.
