Siphons for sinks – which model to choose?

For a siphon to perform its role well, it must be properly matched to the sink. The available siphon models on the market differ in construction, material, type of stopper, method of connection, and compatibility with a given type of sink. The siphon should match the diameter and shape of the drain(s), the material of construction, and the number of chambers in the sink.

Due to their construction, we can distinguish between vertical bottle siphons, horizontal pipe models (in the shape of a U), and non-standard siphons. Bottle siphons are the most popular due to the small amount of space they occupy under the sink. On the other hand, pipe siphons perform well in larger washing areas and are resistant to clogging. 

Space-saving siphon – when is it worth using?

The space in the cabinet under the sink is used not only to hide elements of the water and sewage installation but also to store waste containers, cleaning agents, and other items. Traditional siphons, with elbows and pipes, can take up most of the space in the cabinet, making it difficult to put in and take out things and creating chaos – especially in small washing areas. When space is limited, it is worth reaching for special space-saving siphons. They feature a compact, thoughtful design that allows for maximum use of every centimeter. They are often significantly smaller than standard models or designed to fit against the back wall of the cabinet. By using this type of siphon, you have the chance to fit a lot of items in the cabinet, easily take them out, and keep order under the sink. Which space-saving siphon is worth choosing?
