In the case of prolonged non-use or low atmospheric pressure, the foul-smelling gases can spread throughout the building. If, for example, washbasins are not used for a longer period of time, commercially available arch siphons dry out and an odour stop is not given anymore. Regular flushing or filling of siphons, however, means additional effort for owners outside the time of use. Floor drains, drains of dry urinals, or installations with little installation space do without
these siphons and odours can return unhindered at any time.

The MwStop® Home odour seal focuses precisely on this problem and offers an optimal solution to prevent bad odours from the drainage system.
The self-acting odour seal has a long service life, is extremely easy to install in existing drains and can be used in many areas. The specially shaped sealing lip reliably prevents sewer gases from escaping.
