Air Admittance Valves | Durgo Valve | Durgo Valves
Durgo Valves, commonly known as Air Admittance Valves (AAVs), are critical components in modern waste plumbing systems. They are designed to allow air to enter the plumbing system when negative pressure is sensed, preventing the loss of water seals in traps which can lead to unpleasant odours and unhygienic conditions.
Practical Uses of Durgo Valves
Durgo Valves are used in various scenarios where conventional venting is not possible or practical. They are typically employed in internal plumbing systems where connection to an external vent is difficult, such as in high-rise buildings, basement bathrooms, or in renovations where access is limited.
Types of Durgo Valves
- Universal Waste Pipe Air Admittance Valves: These valves are adaptable to all sizes of waste pipes and are suitable for most residential and commercial applications.
- Specific Size Air Admittance Valves: Ranging from 32mm to 110mm, these valves cater to specific pipe diameters, offering a more precise fit and seal for systems with known pipe sizes.
Color Variants: For aesthetic or coding purposes, these valves come in different colours to match or identify different plumbing systems.
Selecting the Appropriate Durgo Valve
When selecting a Durgo Valve for your needs, consider the following factors:
- Pipe Size Compatibility: Ensure the valve is compatible with the size of your waste pipe. Universal valves are versatile, while specific size valves provide a tailored fit.
- Colour Coding: Choose a colour that either matches your plumbing fixtures or follows the colour coding of your plumbing system.
Airflow Requirements: Different valves allow for varying amounts of airflow. It’s essential to choose one that can handle the airflow requirements of your plumbing system to maintain efficiency.
In summary, Durgo Valves are essential for maintaining a hygienic and odour-free plumbing system where conventional venting is not feasible. With options ranging in size and colour, one can find a valve that fits both the practical and aesthetic needs of their plumbing system.
