Discover the many features of the Stop Silent Light backwater flap!
The stench of sewer gases is unpleasant. Air or gases in the pipeline start to move with a low temperature difference that is called the chimney effect. The installation of a Stop Silent Light valve prevents the movement of these gases out of the sewer system. [click here to learn more about it]
Flood walls can prevent street flooding but sometimes the road gullies are still connected to water bodies that allow back flow through the street drainage system. Installation of Stop Silent Light check valves on these gully connections prevent this back flow and ensure that the roads are not flooded. [click here to learn more about it]
The Stop Silent Light® expander clamp can be operated from both sides and allows installation in the inlet or outlet of the access chamber/junction.
It can either be installed in existing drainpipes or manholes.

Due to a small build-up of water, a relatively low pressure is exerted on the diaphragm, which then opens upwards. If the flow stops, the sealing lip restores and closes the valve. In back pressure, the rubber membrane is filled and pressed against the pipe wall.
