The McAlpine VP50-100 Ventapipe 50 is an air admittance valve designed for use in plumbing systems to prevent the loss of water trap seals due to negative pressure. The valve features a dual fit synthetic rubber finger seal outlet that can fit both 3"/75mm and 4"/110mm soil pipes, making it a versatile component that can be used in a range of applications.

The VP50-100 also incorporates a 2" outlet, which allows for the discharge of waste water from a variety of sources, such as sinks and baths.

Similar to the VP100, the VP50-100 is also a one-way valve that allows air to enter the plumbing system, but does not allow gases to escape into the living or working space. This is important for maintaining a healthy and safe environment, as sewage gases can be harmful to health.

The McAlpine VP50-100 Ventapipe 50 is also designed and manufactured by McAlpine, a leading manufacturer of plumbing components in the UK. The valve is made from high-quality materials to ensure it is durable and long-lasting.

Overall, the McAlpine VP50-100 Ventapipe 50 Air Admittance Valve is a reliable and effective component that can be used to prevent the loss of water trap seals, discharge waste water and maintain a healthy and safe environment in plumbing systems.
