All KESSEL backwater valves are manufactured in accordance to EN norms and have also passed KESSEL’s strict in house testing. This testing actually requires backwater valves to perform above the EN norm requirements. The Staufix valve is being successfully installed every day in problem areas all over the UK.

  • Multiple installation possibilities – eg: in an exposed mainline wastewater pipe, in a concrete slab or outside the building in an inspection chamber.
  • Simple tool-free servicing – the cover can be unlocked and removed by hand.
  • Constructed entirely from ABS, meaning no more metal, no more rust.
  • 2-Component production technology seals gaskets with valve. No more lost or improperly installed gaskets.
  • Stainless steel rodent protection flap – unwanted guests are not allowed through.
  • Perfect for renovation – other valves with large drops are difficult to install but the Staufix offers minimal drop between inlet and outlet (only 7 mm).
