Siphon: what is it for?

The siphon is a piece in the shape of an elbow pipe or bottle that connects the drain to the drainage system. It is located under a sink, sink or shower tray and consists of 3 holes. One to connect the bung, another to connect the drain pipe and the last one to allow to unblock it if necessary. The siphon must always be filled with water (at least 50 mm).
This water acts as a "plug" hermetic between your sanitary equipment and the drainage system (everything in the sewer) and also helps prevent the rise of bad odors and the possible passage of animals. Even if it is not visible, the siphon must always be accessible to be able to unclog it if necessary.
There are different types of siphon: shower siphon which fits into the ground, the double siphon to connect 2 bins or 2 sinks, the floor siphon for walk-in showers (water retention), siphon "space saving", siphon for household appliancer... Ask a professional for advice on which model is best for your installation.

How to install a siphon?

Installing a siphon is a fairly simple operation that requires few tools and little time. Depending on the device to be connected, the outlet of the siphon will be different. A horizontal outlet connects the drain to the wall and a vertical outlet to the floor.
If it is a siphon replacement, consider placing a container underneath before disassembling it. Then unscrew the new siphon to install in 2 parts. Place the top part on the thread of the drain plug and the lower part on the drain pipe. Connect the 2 parts by screwing the siphon collar. Tighten the threaded rings properly and if necessary, use a wrench for a perfect result. After placing the siphon, it is important to check the tightness of the seals. To do this, place a bucket under the siphon and open the tap to run the water. If the siphon is not watertight, just tighten the threaded rings and check that it is tight.
