Through-flow inspection chamber with storm gate – a reliable connection to the sewer system

The through-flow inspection chamber with storm gate is a key element of sanitary or rainwater drainage systems, designed for installation in a branch pipe between the building and the main network. It not only provides the function of an inspection chamber, allowing easy access for inspection and cleaning, but also acts as an effective barrier against flooding. Made of durable polypropylene (PP), resistant to corrosion and mechanical damage, it guarantees long-lasting and trouble-free operation.

Construction and installation – flexibility and simplicity

The inspection chamber is supplied with two extensions with a total length of 140 cm, allowing it to be placed in an excavation up to 180 cm deep. This makes the installation flexible and adapts to different terrain conditions. If a greater depth is required, additional extensions (cat. no. PRZ70) can be purchased. The profiled bottom of the inspection chamber ensures stability and optimal flow of media. The storm gate allows for quick and convenient closing of the inspection chamber, minimizing the risk of contamination or unauthorized access.
