No fouling gases

It was a painful experience when we had the basement full of water twice in a short space of time. The quickest and most efficient solution to solve the backwater problem is Stop Silent® SL13 (formerly Light). We were also able to order the valve Express so that it could be installed as quickly as possible.

Express Installation

Foul-smelling sewer gases were getting into my house through the sewer system. After we installed a Stop Silent® SL13 (formerly Light), the odor problem was reliably resolved.

Easy to Retrofit

Specializing in conversions, it is becoming increasingly common for the basement to be converted into a living space, and we install the easy-to-install Stop Silent® SL13 backflow preventer in the wastewater pipes to ensure that this valuable space is not flooded under any circumstances. Retrofitting is also possible without any problems.

No Electronics

An electronic backflow preventer was installed for a customer. The electronics failed twice. After this last incident, we recommended Stop Silent® SL13 (formerly Light) to the customer, as this valve operates completely autonomously.

Save Lives

We had problems with frogs and other small animals entering the reservoir through the overflow. Stop Silent® SL13 (formerly Light) also works as a frog flap, saving the lives of many small animals.
