110mm Soil Pipe Air Admittance Valves

Air admittance valves (AAVs), also known as Durgo valves, are used to prevent sewer gases from entering a building. They are typically installed in soil pipes, where they allow air to enter the pipe to prevent a vacuum from forming. AAVs play an important role in maintaining a healthy and safe indoor environment.

Benefits of Air Admittance Valves

Improved indoor air quality: AAVs prevent sewer gases from entering a building, which can improve indoor air quality and reduce the risk of health problems.
Reduced risk of blockages: AAVs help to keep soil pipes clear of blockages by allowing air to enter the pipe. This can reduce the need for costly repairs and maintenance.
Easy installation: AAVs are relatively easy to install, and they can be used in both new and existing buildings.

Features of 110mm Soil Pipe Air Admittance Valves

110mm soil pipe air admittance valves are specifically designed for use with soil pipes with a diameter of 110mm. They typically feature a durable plastic construction and a diaphragm system that opens to release pressure build-up and then closes again to prevent sewer gases from backflowing into the building.

When to Use Air Admittance Valves

AAVs are typically used in situations where it is not possible to install a traditional vent stack. This can include:

Buildings with limited space: AAVs are much smaller than traditional vent stacks, making them ideal for buildings with limited space, such as apartments and townhouses.
Buildings with multiple drainage systems: AAVs can be used to vent multiple drainage systems within a single building, which can save time and money on installation.
