What are the main brands of siphon drainage on the market at present?

Siphon drainage is gradually understood by us and recognized by the market. We are familiar with foreign brands of siphon drainage: Geberit, Weiwen siphon drainage and Jetstream. In recent years, many good brands have emerged in China, such as Beijing Taining Jiangsu Jinchi, Jintenghong Suction and Drainage, Jinghong Siphon, Liu Chuang Siphon Drainage, Yongli Siphon and Yitong Siphon. All of the above are well done. Of course, foreign brands have a long history and their prices are relatively higher than those in China. Domestic brands have developed well in recent years, and their quality and efficiency have gradually improved. For reference only.
