Kessel

The backflow double lock Staufix by Kessel reliably protects against backflow from the sewer and flooding of the basement. The Staufix is ​​for installation in an exposed sewer, has two self-closing flaps and a handlockable emergency stopper. With the one-hand quick release, maintenance and cleaning can be done without tools. Also works as a backflow preventer and protects against foreign infiltration from other drainage points or residential units - also to use as vermin protection.
