Through-duct sleeve 315x160 with storm shutter for corrugated DN 315mm rising pipe (pipe outer diameter 355mm), with 140cm extension K35P16ZB

Through-flow inspection chamber with storm gate – reliable wastewater flow control

The through-flow inspection chamber with storm gate is a key element of a sanitary or rainwater drainage system, designed for installation in a pipe between the building and the main network. It not only provides access for inspection and cleaning but also effectively protects against the effects of sudden floods and flooding. The storm gate design minimizes the risk of sewage backflow during heavy rainfall.

Design and application

Made of durable polypropylene (PP), the inspection chamber is characterized by high corrosion resistance and mechanical damage resistance. The profiled bottom provides structural stability and facilitates the removal of contaminants. With an inner diameter of 315 mm, it is compatible with corrugated pipes with an outer diameter of 355 mm, making it easy to integrate with existing infrastructure. The included extensions (totaling 140 cm) allow for flexible adjustment of the installation depth to the conditions on the construction site – without the need for additional purchases.

• Inspection function: Allows easy access to control and clean the sewage system.
• Flood protection: The storm gate effectively blocks the backflow of sewage during heavy rains.
• Versatility: Designed for both sanitary and rainwater drainage.
• Easy installation: The kit includes extensions allowing the chamber to be positioned at different depths (up to 180 cm). Additional 70 cm extensions (cat. no. PRZ70) can be purchased if necessary.
• Durability: The polypropylene body guarantees long-term operation even in harsh environmental conditions.

Product parameters and features

The inspection chamber has been designed with ease of installation and reliable operation in mind. Its construction takes into account the specifics of drainage systems, providing optimal flow and safety parameters. The lack of caps on the inlet openings allows for free flow of media, and the black color of the body provides a discreet appearance in the surroundings of drainage pipes. The height from the ground level to the inner bottom of the pipe is 3000 mm, which allows adaptation to various installation configurations. The outer diameter is 365 mm, which is important when planning connections with other elements of the drainage system.
