WhiffAway developed the Closed System concept in 2012, based on our understanding of operational problems from other plumbing entities, such as the wash hand basin, floor drain and shower gully area.

Common operational problems identified included back pressure, blow back, evaporation and siphonage. This results in increased odours in washroom environments.

Our patented range of Closed Systems delivers a simple solution for both specification and retro-fit environments. This removes the reliance of conventional water seals and replaces it with a physical barrier, leading to a more hygienic and odour free washroom environment.
