The Altecnic 22mm Fill & Flush Valve is a plumbing component used primarily in heating systems, such as central heating or underfloor heating systems, to control the filling and flushing of the system. This type of valve allows for easy filling of a heating system with water from the mains supply and facilitates flushing to remove any air or debris that could affect the system's efficiency.

Here are some key features and functions of the Altecnic 22mm Fill & Flush Valve:

• Filling Function: It enables the controlled introduction of water into a closed heating system, ensuring that the system is properly pressurized.
• Flushing Function: It allows for easy drainage and flushing of the system to remove air, dirt, or other contaminants that may have accumulated over time.
• Size: The "22mm" refers to the diameter of the valve, making it suitable for pipework with a 22mm external diameter.
• Materials: Made from high-quality brass to ensure long life and resistance to corrosion.
• Connection: The valve comes with compression fittings, making it straightforward to integrate into existing pipework.

This type of valve is commonly used by professional plumbers or heating engineers during system maintenance, installation, or repairs.
