Baxi Cartridge Repair Kit (720003100)
The Baxi Cartridge Repair Kit is the primary internal component used to toggle the boiler's output between the central heating circuit and the domestic hot water system. When the actuator motor pushes or pulls this cartridge, it opens or closes the flow to the plate heat exchanger. Replacing the internal cartridge is a reliable and cost-effective way to fix a sticking valve without the need to replace the entire brass manifold.
Seamless Switching: Facilitates the rapid transition between central heating and hot water modes for maximum comfort.
Leak-Proof Integrity: Equipped with high-quality internal seals and O-rings designed to withstand constant pressure and high temperatures.
Direct Fit: Manufactured as a genuine replacement for part number 720003100 (also compatible with 7656807 and 248733).
Cost-Efficient Repair: A professional-grade solution to resolve common issues like lukewarm water or radiators heating up unexpectedly.
