Genuine Baxi 720003100 3-Way Valve Cartridge – Original Plain Boxed Part

Restore precise water flow control within your boiler with the Genuine Baxi 720003100 3-Way Valve Cartridge. This critical internal component sits within the diverter valve assembly and acts as the moving seal that directs water either into your central heating system or to your domestic hot water taps.

Over time, the internal O-rings, seals, and moving parts of the cartridge can degrade, scale up, or seize due to system debris and thermal wear. This often leads to symptoms such as radiators getting hot when they should be off, lukewarm hot water, or persistent leaks originating from the diverter valve body. Replacing the cartridge with this brand new, original manufacturer part restores the valve’s ability to seal tightly and switch modes correctly, ensuring efficient boiler operation.

Supplied securely in plain protective packaging, this authentic Baxi component provides the exact quality and perfect fit required for a professional-grade repair. Trust Warwick Heating Supplies to provide the genuine parts necessary to keep your heating system running reliably.
