Siphon

A siphon is a key product from the sanitary sector. In essence, it’s a drain pipe attached to the underside of a sink, a shower or bathtub, through which wastewater goes into the sewer system.

But a
siphon is much more than just a water pipe. A siphon is the odour trap of sewage pipes. What does this mean?

Our kitchen, bathroom, garage and laundry room are connected to the sewer system by water pipes. So why doesn't our bathroom smell like sewage? This is where the siphon comes into play. Thanks to its U-shaped, S-shaped or vessel-shaped bend, the lower part always remains filled with some liquid (so-called sealing water). This liquid prevents the passage of malodorous gases from the sewer back into your home. A siphon is therefore lets through water, but not odour or gas.

There are various types of siphons that differ in size, shape and number of bends. The principle of operation is identical for all siphons. The most common are the tubular siphon and the bottle siphon.

The tubular siphon is characterised by its curved S or U shape, in which the sealing water collects. It’s often made of plastic and is not necessarily visually appealing. Tube siphons are therefore often hidden in a sink base cabinet and often found in the kitchen.

The bottle siphon collects the sealing water in an often elongated, bottle-shaped container. Unlike the tubular siphon, the bottle siphon is often made of metal and looks much more elegant. Bottle siphons are found mainly in the bathroom next to the sink.

In addition to siphons, we also offer siphon attachments, siphon connections, reductions for siphon and other siphon accessories in our online shop.
