Inspection shaft DN 315/160/500 with non-return valve, straight-through, plastic sewage shaft

Product detailed description

The straight-through sewage inspection shaft DN 315/160/500 with non-return valve is used - installed on the sewage pipe, generally to allow a drain rod ("mole") to be inserted into the sewage pipe to clear the given branch when it gets blocked. If the sewage pipe is longer, we recommend installing inspection shafts every 20-25m. The sewage inspection shaft with non-return valve prevents wastewater and sewage from flowing back into the building, or rodents from entering the premises. Use of a shaft with a non-return valve: The sewage inspection shaft with non-return valve is designed for use in sanitary waste systems or for rainwater. The recommended installation location for a shaft with a non-return valve is the sewage pipe between the building and the main waste network. The sewage shaft with non-return valve serves as an inspection shaft protecting buildings against flooding. Advantages of using a shaft with a non-return valve: Standard installation of a non-return valve requires the use of a shaft made of plastic, concrete or other solid material with a diameter in the range of 800 to 1200 mm, and its installation often requires the use of heavy machinery. The sewage shaft with non-return valve can be easily installed by one person without any heavy machinery. A very simple and effective mechanism, from which the component can be removed without a person having to get inside the equipment, allows the use of shafts with a much smaller diameter, DN 315 and DN 400. The inspection shaft with non-return valve also does not require a maintenance specialist. The highest quality stainless steel and polypropylene used in manufacturing make the shaft with non-return valve resistant to corrosion, frost and chemical agents. The sewage shaft with non-return valve is installed without the use of heavy machinery and is resistant to expansion. The maximum permitted installation depth of the inspection shaft with non-return valve is 5m. The maximum temperature of the medium flowing through the shaft is 95°C.
