The retention regulator is intended for installation in cisterns to control the amount of water draining into the canal. Freely suspended from the floating ball is the inlet filter . This ensures that the downstream pipes and lines are always free of blockages and that the water can flow off in the specified quantity.

The flexible connection hose adapts to the respective water level. The material is chosen so that the hose remains permanently flexible without cracking due to the up and down movement. The outflowing water is then discharged into the sewer system through a KG socket plug DN 110.

  • Floating ball (150 cm diameter)
  • Stainless steel ring
