Abstract
The present invention provides an in-line valve particularly suitable for draining facilities to avoid odour penetrating habitable spaces or backflush of drainage liquids. The in-line valve comprises a body, preferably made of two engageable parts, an inset and a duckbill valve. The insert is located within the valve body and surrounding the duckbill valve. The insert funnels liquid from the valve inlet to the valve outlet, so that puddling in the valve body is avoided and therefore no water is accumulated, which could lead to odours or microorganisms proliferation.
