Full details
The Plumbright AF110 Push Fit Air Admittance Valve is designed for plumbers and homeowners seeking to maintain efficient sanitary pipework ventilation. Its primary benefit is preventing foul gasses from escaping into a building while allowing air entry, ensuring proper drainage function. A key consideration is its installation requirements, which must adhere to BS EN 12380 standards. This valve facilitates airflow, prevents odor escape, and can double as a secondary rodding point for blockages, operating effectively in temperatures from -20°C to +60°C without insulation.

FAQs
What is an Air Admittance Valve (AAV)?
An Air Admittance Valve is a device that allows air to enter a plumbing drainage system, preventing sewer gases from escaping into the building while preventing siphonage of trap seals.
Can the Plumbright AF110 be installed horizontally?
The valve is designed for vertical installation to ensure proper function and prevent debris from entering the mechanism. Always refer to installation guidelines.
Does this valve require power or external ventilation?
No, the Plumbright AF110 is a passive device that operates automatically based on pressure changes within the drainage system.
What does 'A1 approved in accordance with BS EN 12380' mean?
This certification indicates that the product has met the stringent safety and performance standards set by the European standard for air admittance valves.
How do I know if my drainage system needs an AAV?
AAVs are typically required in plumbing systems where venting to the outside is difficult or not possible, especially in renovations or extensions, to ensure proper drainage and prevent odors.
What is the airflow capacity of the AF110?
The Plumbright AF110 has an airflow capacity of 43 L/s, ensuring efficient air admittance.
Can this valve be used to vent a new system?
AAVs are primarily used to supplement or replace traditional vent pipes where they cannot be installed. Always consult local building codes and a professional plumber for system design.
Troubleshooting
Drainage system gurgling or slow draining.
Check if the Air Admittance Valve is functioning correctly. Ensure it is not stuck closed or blocked. Inspect for any debris preventing it from opening.
Unpleasant odors detected in the building.
Verify that the Air Admittance Valve is properly sealed and functioning. If the valve is old or damaged, it may not be effectively preventing gas escape. Consider replacement.
Valve does not appear to open or close.
Ensure there are no obstructions around the valve mechanism. Test by creating a vacuum in the system; the valve should open to admit air.
Water seal in traps is siphoned out.
The valve may not be opening adequately to equalize pressure. Check for proper installation and ensure it is not being overwhelmed by excessive flow rates.
