Let's explore the various options available and their applications to help you select the appropriate valve for your needs.

Types of Air Admittance Valves:

1. 82/110mm Air Admittance Valves (e.g., AF110 & AV110):
   • Typically used in larger residential or commercial buildings, these valves accommodate a broader range of pipe sizes and are available in various colours to match your plumbing system.
   • Ideal for scenarios where a robust air admittance solution is required, often utilised in main vents or larger branch vents.
2. 32mm Air Admittance Valves (AV32):
   • Perfect for smaller waist fixtures or as secondary ventilation in a residential setting.
   • These are more compact and typically used in kitchen islands, bathroom sinks, or anywhere space is limited.
3. Universal Waste Pipe Air Admittance Valves:
   • Designed to fit a variety of pipe diameters and applications, these versatile valves are suitable for almost any residential setting.
   • They offer a flexible solution for those looking to retrofit or upgrade their existing waste systems without specific size requirements.
4. Vaillant Horizontal Air Flue Ducts and Extensions:
   • These specialised components are designed for use with specific boiler systems, enhancing the efficiency and safety of your heating installation.

   • Featuring both horizontal ducts with elbows and straight duct extensions, they are essential for directing exhaust gases safely out of a property.

      

Practical Uses:

• Residential and Commercial Buildings: To prevent the ingress of sewer gases and maintain water seals in traps without the need for roof penetration and traditional pipe venting.
• Remodelling and Retrofitting: Ideal for updating or installing new plumbing systems where traditional venting is impractical or impossible.

• Specialised Heating Systems: Certain products in this category are designed to work with heating systems, ensuring safe and efficient operation.

   

Selecting the Right Air Admittance Valve:

When choosing the right air admittance valve, consider the following:

• Pipe Size & System Compatibility: Ensure the valve fits your specific pipe size and is compatible with the rest of your plumbing system.
• Building Codes & Standards: Verify that the product meets local building codes and standards.
• Venting Capacity: Choose a valve that can handle the venting requirements of your fixtures or system.
• Durability and Quality: Opt for valves from reputable manufacturers to ensure long-term reliability and performance.
