Backwater protection
Backwater protection
Backwater protection is crucial for preventing flooding in buildings during heavy rain or sewage system failures. The document outlines solutions such as premium and classic backwater valves, and installation options for both new constructions and renovations.
Backwater occurs when sewage systems cannot handle heavy rainfall, leading to potential flooding in basements. Causes include blockages, pump failures, and high water levels in nearby streams or rivers. Effective protection involves using backwater valves or lifting stations to prevent wastewater from entering buildings.
Choosing the right backwater protection depends on the type of wastewater (black or grey water) and the building's drainage system. Options include installing backwater valves inside buildings or in external chambers to save space. Retrofitting is possible for older buildings to enhance protection.
Compliance with EN standards is crucial for backwater protection systems. The document details various types of backwater valves as per EN 13564, highlighting their applications and installation requirements.
Premium valves, such as Pumpfix F and Staufix FKA, offer advanced features like motor-driven flaps and integrated pumps for effective wastewater management during backwater events. These systems are designed for easy installation and maintenance.
Illustrations provide guidance on installing backwater protection systems in different scenarios, including exposed pipes, concrete floors, and underground setups.
KESSEL offers comprehensive systems, including lifting and pumping stations, to complement backwater valves. These solutions ensure reliable protection against backwater in various building types.
The Pumpfix F and Staufix FKA systems are equipped with a Comfort control unit featuring a self-diagnosis system (SDS) for enhanced safety. They are suitable for installation in both concrete slabs and exposed wastewater pipes. The systems are compliant with EN 13564 standards, ensuring reliable performance.
The Pumpfix F Komfort system is designed for easy installation, especially when wastewater pipes are exposed across basement floors. It operates by discharging wastewater through gravity under normal conditions and activating a pump during backwater events. The Staufix FKA Komfort features a motorized backwater valve that seals during backwater events and reopens automatically. Both systems include a sealing gasket set for installation in waterproof concrete.
Key features include a plug-and-play control unit, integrated drain function, variable upper section for height adjustment, and a fully open pipe passage during normal conditions. The systems are designed for renovation work with a minimal gradient of 9 mm.
The document lists various accessories, including gasket sets, extension sections, optical probes, and alarm systems, which enhance the functionality and installation flexibility of the backwater protection systems.
These systems offer a cost-effective solution for backwater protection, preventing potential property damage from basement flooding. The integrated SDS ensures regular and automatic functional testing, providing peace of mind for users.
The document outlines the specifications for different backwater valves, including the Pumpfix F, Staufix FKA, and Staufix SWA models. These valves are designed for installation in concrete slabs or exposed pipes and are available in various diameters ranging from Ø50 to Ø200 mm. The valves are made of polymer, ensuring corrosion-free operation.
Installation procedures are highlighted, emphasizing the ease of retrofitting and tool-free maintenance. The valves can be installed in both new constructions and renovations, with minimal drop between inlet and outlet for easy installation.
The valves comply with EN 13564 standards, ensuring they meet the necessary requirements for backwater protection. The document advises checking local regulations for specific certification needs.
The document recommends using these backwater valves for protecting individual drainage fixtures like showers, sinks, and washing machines below the backwater level. It also suggests using the valves for wastewater systems without sewage to prevent flooding and rodent intrusion.
Several conversion kits are available, allowing for the upgrade of existing systems to include motorized backwater valves with pumps or twin flap systems. These kits enhance the flexibility and functionality of the installed systems.
The valves feature self-closing flaps, stainless steel rodent protection, and are designed for easy maintenance. The modular design allows for straightforward installation and adaptation to various ground levels.
The valves are suitable for use in residential, public, municipal, and industrial sectors, providing protection against backwater and additional security against vermin.
The document provides detailed specifications and installation guidelines for backwater inspection chambers designed for wastewater management. These chambers are constructed from polyethylene, ensuring durability and resistance to aggressive wastewater and root infiltration. They are suitable for underground installation and come with a 20-year warranty.
The chambers are available in various heights (H1 to H5) and diameters (Ø 1000 and Ø 800). They feature a monolithic design with integrated access steps and are watertight. The chambers include triple 160 mm hub type gasketed inlets and spigot type outlets (Ø 160 mm and Ø 200 mm) compatible with PVC and PE-HD pipes.
The chambers are designed for easy assembly with lightweight components and a simple connection technique. They can handle groundwater depths up to 2000 mm. Accessories include conversion kits for backwater valves (KESSEL Staufix SWA, FKA, and Pumpfix F), upper sections for height adjustment, and various cover plates (Class A/B/D).
The chambers are equipped with cleaning openings for the installation of KESSEL backwater valves. They ensure backwater-proof and gravity-fed wastewater flow from buildings to sewers. The document also describes hybrid lifting stations for sewage-free wastewater and rainwater, featuring motorized backwater flaps and optional gate valves for enhanced protection.
The system offers long-term reliability with resistance to sedimentary deposits and aggressive media. It includes standard connections for basement and roof drains, and the cover for garden installation is part of the supply scope.

Backwater protection Backwater protection – Everything specialists need to know What is backwater ? All the outlet pipes from drainage fixtures in buildings (washing machines, showers, toilets etc.) are connected to the sewer, forming a linked pipe system. If the wastewater cannot flow freely through the sewer e.g. after heavy rainfall or due to blockages in the sewer pipes, it is pushed back into the connected outlet pipes and can flood all the areas of the house which are below the backwater level, including any fixtures and furnishings etc. Backwater is always possible For economic reasons,...

The right product selection Heavy rainfalls more common Backwater protection Backwater protection – Everything specialists need to know The problem of backwater has always existed, because for economic and technical reasons, sewage pipes are designed for average rainfall. This means the storm sewage pipe can fill up very quickly in the event of a cloudburst. What is new is that meteorologists predict that heavy rainfalls will increase in future. The reason: global warming leads to more evaporation from the earth’s surface. This fills rain clouds which then discharge torrential rain. The selection...
