The Baxi 248065 Diaphragm for 3-Way Valve is a genuine Baxi replacement component designed to support the proper operation of the 3-way diverter valve in compatible boiler systems. This precision-engineered diaphragm forms a flexible, pressure-responsive sealing surface inside the valve, allowing it to switch effectively between directing heated water to the central heating circuit or to domestic hot water on demand. Manufactured to Baxi’s exact quality and durability standards, it should be fitted by a qualified heating engineer during servicing, maintenance, or when replacing a worn or faulty diaphragm to restore smooth valve action.

Compatibility for the 248065 diaphragm includes Baxi Combi and Main Combi boiler models that utilise this specific internal valve seal design. Always verify your boiler’s exact model and parts requirements before installation to ensure correct fit and reliable performance.

Using a genuine Baxi 3-way valve diaphragm helps maintain accurate water routing, supports dependable switching between heating and hot water modes, and contributes to the long-term efficiency and reliable operation of your central heating and hot water system.
