WaBack is an "all in one" installation that works as both as an inspection chamber and as an automatic non-return valve. The WaBack access chamber is a complete inspection chamber.
The solution is to be found in NPS 4" in NPS 16" chamber and NPS 4", NPS 6" and NPS 8" in NPS 40" chamber.
The solution protects against:
- Backflow
- Flooding
Some advantages of the solution:
- Works immediately and automatically
- Is always open for flow under normal operating conditions and has full drainage ventilation
- Is supplied complete with inspection chamber and non-return valve in one
- Provides easy access from ground level during inspection and maintenance
- Is made of corrosion-free material, making for a long service life
- Is tried-and-tested - has been on the market for more than 30 years
The WaBack is also available without an access chamber, and is then called the WaBack non-return valve.
