Air Admittance Valve Internal

The Air Admittance Valve (Internal) is a reliable ventilation solution for internal soil and waste drainage systems. It automatically opens to allow fresh air into the pipework when negative pressure occurs and closes immediately afterward to prevent unpleasant sewer odours from entering the building.

Manufactured from durable, high-quality PVC, the valve is lightweight, corrosion-resistant, and designed for long-lasting performance. It eliminates the need for external vent pipes in many installations, making it ideal for bathrooms, kitchens, utility rooms, and residential or commercial plumbing systems. Its compact design allows for quick installation and low maintenance while ensuring efficient drainage system ventilation.
