There are models of siphons, with iron releases, which are attached to the overflow and siphon body using a bolt. Their installation is easier than plastic, and the view is more beautiful. Unfortunately, there is no perfection throughout the world, in the exchange of stainless steel, nickelled iron (unusually in devices, production of «Made in China») is often used on them, and after a few years it begins to eager. Fastening bolts and nuts are similarly commonly ordinary, in much better the zinc. Such a bolt is only a year later — 2 tightly clicks to the nut and, not to spoil the siphon (for example, for cleaning) is very problematic.
Subsequently, how the siphon is installed, put the bathroom itself.
