The Grate Seal Basin Waste is specifically designed for installation in basins in domestic and commercial situations. The silicone valve housed within the stainless steel body acts as a one way valve, allowing the flow of water, whilst preventing airborne bacteria, odours and insects etc, escaping from the sewage system into habitable zones.
