Costly renovations of damaged rooms? A thing of the past for households that protect themselves against backflowing wastewater with a Stop Silent® SL13 backflow preventer.

The open outlet of a pipe into the natural environment allows insects, amphibians and reptiles to enter. The backflow protection with frog flap function of Stop Silent® SL13 prevents such animals from entering.

The smell of duct gases is unpleasant and unnecessary. Air or gases in pipes start to move at low temperature differences, creating the so-called stack effect. The installation of a Stop Silent® SL13 backflow preventer prevents the movement of sewer gases and the smell is eliminated. Problem solved!

Effective drainage of railroad systems or roads is necessary for safety reasons. At this point, the Stop Silent SL13 backflow flap ensures that no water flows back into the drainage system in the event of heavy rain or flooding, softening the subsoil and jeopardizing its stability.
