DN 315/160/5000 In-Line Inspection Shaft with Non-Return Valve, Plastic Sewer

Product detailed description

The DN 315/160/5000 in-line inspection shaft with non-return valve is used - fitted onto sewer pipework, generally to allow a "mole" (drain rod) to be inserted into the sewer pipe to clean out the given branch when it becomes blocked. If the sewer pipe is longer, we recommend fitting inspection shafts every 20-25m. The sewer inspection shaft with a non-return valve prevents backflow of waste water and sewage into the building, or the passage of rodents into dwellings.   Use of the shaft with a non-return valve: The sewer inspection shaft with a non-return valve is designed for use in sanitary waste water systems or for rainwater. The recommended installation location for the shaft with a non-return valve is the sewer pipe between the building and the main waste water network. The sewer shaft with a non-return valve serves as an inspection shaft protecting buildings from 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 sewer shaft with a non-return valve can be easily installed by a single 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 unit, allows the use of shafts with a much smaller diameter, DN 315 and DN 400. The inspection shaft with a non-return valve also does not require a maintenance specialist. The highest quality stainless steel and polypropylene used in its manufacture make the shaft with a non-return valve resistant to corrosion, frost and chemical agents. The sewer shaft with a non-return valve is installed without the use of heavy machinery and is resistant to thermal expansion. The maximum permitted installation depth of the inspection shaft with a non-return valve is 5m. The maximum temperature of the medium flowing through the shaft is 95°C. The DN 315/160/5000 in-line inspection shaft with non-return valve includes: 315/160 in-line shaft base - straight, with non-return valve 315 shaft cover 315 smooth shaft pipe Watch the video: https://www.youtube.com/watch?v=ARqwDGf5Mhg
