## Long description

The Kessel 73150 backwater valve is a robust and reliable solution engineered for DN 150 pipe systems. Manufactured from high-grade, impact-resistant plastic, this valve serves as a critical barrier against sewage backflow, effectively safeguarding residential and commercial properties from the risks of flooding caused by sewer system backups. Its design focuses on operational longevity and consistent performance in demanding drainage environments.
Advantages
This backwater valve offers exceptional durability due to its high-quality plastic construction, which is resistant to corrosion and chemical degradation common in wastewater systems. The design ensures a tight seal, preventing the ingress of sewage into building interiors during peak load or system failure. Its lightweight nature facilitates easier handling and installation compared to traditional metal alternatives, while the internal mechanism is optimized for minimal flow resistance, ensuring efficient drainage under normal operating conditions.
Suitable for
Residential basements and ground-floor drainage systems
Commercial buildings connected to municipal sewer networks
Protection of sanitary installations against backwater pressure
New construction projects and retrofitting existing drainage lines
This valve may not be suitable for industrial applications involving highly aggressive chemicals or temperatures exceeding the material's thermal limits. It is also not intended for use in pressurized pipe systems where constant high-pressure flow is present, as it is designed specifically for gravity-based drainage networks.
Key specifications
Nominal diameter: DN 150
Material: High-quality durable plastic
Application: Gravity drainage systems
Function: Backflow prevention
Installation should be performed by a qualified professional to ensure the valve is correctly oriented according to the flow direction. The unit must be accessible for periodic inspection and maintenance to ensure the flap mechanism remains free of debris and operates smoothly. Ensure that the pipe connections are properly sealed to prevent leaks at the joints.
What to consider before purchase
Verify the nominal diameter of your existing pipe system matches DN 150
Check local building codes and regulations regarding backwater protection
Ensure adequate space is available for installation and future maintenance access
Confirm the compatibility of the valve with the specific type of wastewater being drained
Usage recommendations: Regularly inspect the valve at least twice a year to remove any accumulated debris or sediment that could obstruct the flap. Keep the access cover clear of obstructions to facilitate quick maintenance when necessary.
