Potterton 3-Way Valve Assembly Without Bypass – Refurbished | Part No. 7224764 / 5132456

When a combi boiler can only produce heating or hot water — but not both — the 3-way diverter valve is almost always the cause. A stuck, seized, or worn valve body prevents the hydraulic circuit from switching correctly between CH and DHW modes. The Potterton 3-Way Valve Assembly Without Bypass (Part No. 7224764 / 5132456) is the correct OEM-specification replacement for the Performa series and a wide range of cross-brand Baxi and Main models, restoring accurate hydraulic switching and returning the boiler to full dual-function operation.

This is a professionally refurbished genuine component. Each valve assembly is stripped, cleaned, inspected, and function-tested against original manufacturer specifications before dispatch. The without bypass configuration is the correct variant for the listed models — please verify before ordering. Supplied with a full 12-month warranty, quality-checked by experienced engineers.
