Baxi 3-Way Diverter Valve Assembly – Refurbished | Part No. 248727

The 3-way diverter valve is one of the most critical components in a Baxi combi boiler — responsible for switching the flow of hot water between the central heating circuit and the domestic hot water circuit on demand. When this valve fails, the boiler typically loses the ability to produce hot water, gets stuck in heating-only mode, or produces hot water with no heating at all. In some cases, a seized or partially failed diverter valve causes the boiler to short-cycle or lock out entirely. The Baxi 3-Way Diverter Valve Assembly (Part No. 248727) is the correct OEM replacement that restores full combi boiler functionality.

This is a professionally refurbished genuine Baxi diverter valve assembly. Each unit is fully stripped and inspected — the valve body, actuator motor, seals, and internal O-rings are all examined and replaced as required. The assembly is then pressure-tested and function-cycled to confirm smooth, reliable switching between heating and DHW modes before dispatch. You receive full OEM-spec performance at a significant saving over a new replacement assembly.
