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

A faulty 3-way diverter valve in a Baxi Combi Instant or Potterton Performa boiler will cause some of the most noticeable heating system faults — including no hot water, central heating staying on during hot water demand, or inconsistent system switching between the two circuits. The 3-way valve is the component responsible for directing heated water to either the domestic hot water circuit or the central heating system, and when it fails, the boiler can no longer manage either correctly. The Baxi 3-Way Diverter Valve Assembly (Part No. 248727) is the professionally refurbished direct replacement, restoring correct hydraulic switching across the Baxi Combi Instant 80E, 105E, and Potterton Performa range.

This refurbished valve assembly has been professionally rebuilt and fully tested to confirm correct directional switching and reliable operation before dispatch. Part GC No. E68-184. Only 2 units currently in stock. Supplied with a 12-month warranty.

What Faults Does a Failing 3-Way Valve Cause?

When the diverter valve assembly deteriorates or seizes, it typically causes one or more of these symptoms: no hot water output, central heating running when only hot water is demanded, water flowing to both circuits simultaneously, or intermittent switching failures. Replacing the valve with this refurbished 248727 assembly resolves all of these faults and restores correct circuit management.
