Advantages of the backwater valves Stop Silent Light!
- Protection against backflow due to flooding and storms
- Protection against infiltration of insects and amphibians into the pipes
- Prevention of odour nuisances from the sewer network (anti-odour valve)
- Quick and easy installation (can be installed in both direction)
Basement Flooding?
During heavy rainfall the sewer systems can fill up and cause back flow in foul drains. A large volume of water can flow back into basements and other low-lying bathrooms in a short period of time causing problems like overflowing toilets.
Do small animals get into your pipes?
The open outlet of a pipeline into nature allows the ingress of insects, amphibians, birds and rodents into the drainage system. This can cause various problems upstream.
Bad Smell
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.
Street Flooding
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.
Inline check-valve for waste water applications
Our Stop Silent Light check-valve system (by Lasso Technik) is a reliable backflow proventer for use in waste water connections. This perfectly airtight valve is designed for the optimal management of faecal and rainwater with a back pressure of up to 0.5 bar. In addition, this high-quality backwater valve also acts as a nose flap (anti-frog). The valve includes a simple and quick installation which is perfectly suited for private applications as well as industrial companies active in water management. This system secures the pipes and is characterised by quick fixing and friction clamping inside the pipe.
Our check-valve: Functionality
By accumulating water up to approximately pipe filling, 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.
One Minute Installation!
