Rückstausicherungspumpe

Rückstausicher refers to a safety device or system designed to prevent backflow in plumbing and drainage systems. Its primary function is to stop wastewater from flowing back into a building from the public sewer system, particularly during periods of heavy rainfall or sewer overload. This phenomenon, known as a Rückstau or backwater event, can cause significant damage to properties and create unsanitary conditions.

These devices typically incorporate a non-return valve mechanism. When water pressure in the sewer exceeds the pressure within the building's drainage system, the valve automatically closes, blocking any backward flow. There are several types of Rückstausicherungen available, including manual and automatic versions. Manual systems require periodic operation by a building owner, while automatic systems provide continuous protection.

Installation of a Rückstausicher is often mandated by building codes and regulations, especially in areas prone to backwater. Regular maintenance and inspection are crucial to ensure the device functions correctly when needed. Failure to maintain a Rückstausicher can render it ineffective, leaving a property vulnerable to sewer backup. The specific design and placement of a Rückstausicher will depend on the building's drainage layout and local plumbing standards.
