WaBack® Access

Area of use: Flood protection
WaBack Access WB110

WaBack Access has all the benefits of the WaBack non-return chamber. WaBack Access comes in a chamber in which the WaBack non-return chamber is detachable from ground level. This facilitates operation and maintenance, and makes it easy to replace parts. The product is usually used as protection against overload and flooding in drains, and as protection against backflow of surface water and waste water. The product is used to advantage in heavily polluted water. The flow area is completely open, to ensure blockages are prevented.


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.  

Wapro's solutions require minimal maintenance, have a low life-cycle cost and are simple to install. The delivery time for all products is short, and stock items are sent immediately.
