Internal Air Admittance Valve White

FloPlast AV110 Air Admittance Valve Solvent White

Internal Air Valve

The white internal air admittance valve is a cost-effective drainage solution that eliminates the need for traditional vent pipes extending above the roofline, significantly reducing both labour costs and material expenses in soil pipe installations. This innovative valve automatically opens to admit air when negative pressure occurs in the drainage system, preventing trap seal loss and siphonage while sealing completely to block sewer gas escape, maintaining optimal system performance without requiring external ventilation penetrations. Designed exclusively for internal use where environmental debris cannot compromise the valve's airtightness performance, this solvent-welded fitting connects seamlessly to standard 110mm soil pipes. It is available in white, black, or grey finishes to complement various interior design schemes. The valve's precision-engineered mechanism responds instantly to pressure differentials, ensuring reliable operation throughout its service life while meeting building regulations that require adequate ventilation and access for all air admittance valve installations. This essential fitting is invaluable for professional plumbers, building contractors, and renovation specialists working on projects where roof penetrations are impractical, aesthetically undesirable, or structurally challenging. It provides a proven alternative that maintains drainage system integrity while simplifying installation complexity and reducing overall project costs in residential, commercial, and industrial applications.

White Internal air admittance valves eliminate the need to install vent pipes above standard soil pipes, reducing the cost of both labour and materials.

It is recommended that air admittance valves not be used externally, as environmental debris will affect the airtightness performance of the valve.

Internal vents are solvent welded and fit standard 110mm solid pipes.

Available in Black, White or Grey

Ventilation and access must be provided to all Air Admittance Valve installations.
