McAlpine VP100N Solvent Weld Air Admittance Valve, Grey, 150 mm

The McAlpine VP100N Solvent Weld Air Admittance Valve (AAV) is an essential component for modern above-ground drainage systems. Designed to replace traditional open vent pipes, it provides a sealed solution that allows air to enter the system when needed, preventing water suction from trap seals and associated odours. Ideal for internal bathroom and kitchen installations, extensions, and loft conversions where routing a pipe externally is impractical or costly.
