Backflow of wastewater into the building always occurs when the wastewater cannot be optimally drained into the public sewer system. When the capacity of the sewer manholes is exceeded, it flows back into the building.
To prevent this, drainage objects (basement drains, toilets, showers, sinks, etc.) below the backwater level must be protected. Not only heavy rain events but also cross-sectional constrictions caused by deposits or blockages in the sewer system, as well as pipe bursts or pump failures in the public sewer system or floods, mean that wastewater can no longer flow away as quickly as necessary and thus backs up into the building.
Danger: sewage containing fecal matter can enter your basement! Damage to your furnishings, a soaked masonry and foundation as well as a health hazard for people due to the risk of infection are only some of the consequences of backwater. In any case, in addition to the material damage, you can expect an enormous cleaning effort .
