Staufix Premium backwater valve – reliable protection for the sewage system

The Staufix Premium DN100 backwater valve is a key element protecting the sewage system from the effects of sewage backflow. Made of durable plastic, equipped with two mechanical check valves, it provides effective protection in systems discharging wastewater without fecal matter. The valve design allows for quick installation and easy access to components requiring maintenance – without the need for specialized tools.

This valve is particularly useful in situations where there is a risk of flooding due to sudden rises in groundwater levels or failures in the sewage network. Two self-closing flaps, and additionally one of them functioning as an emergency manual shut-off, ensure operation even in the event of a power outage. The ability to exchange the inlet/outlet spigots facilitates adaptation of the valve to various installation configurations, and also allows for connection of old and new elements of the sewage system.

Construction and functionality

The Staufix Premium is distinguished by a well-thought-out design that combines high functionality with ease of installation. Two mechanical check valves ensure reliable operation, and the possibility of emergency manual shut-off provides additional control over wastewater flow. The plastic construction guarantees corrosion resistance and long-term operation. The nominal diameter of DN100 and the outer diameter of 110 mm make the valve compatible with most standard sewage installations.

An additional advantage is the possibility of purchasing a flap protecting against rodents – this option increases the safety of the installation and prevents potential damage caused by pests. The valve meets the EN 13564 standard, which confirms its high quality and compliance with applicable standards. Therefore, by investing in Staufix Premium, you gain confidence in the reliable protection of your sewage system for years to come.
