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

On a Potterton combi boiler, the 3-way diverter valve assembly controls the critical switch between central heating mode and domestic hot water priority. When this valve fails — through seized internals, degraded seals, or a failed actuator — the boiler typically presents as stuck in one mode: delivering hot water but no heating, or heating only with no DHW output. A valve that fails in a mid-position can also cause continuous pump running or brief, intermittent lockouts. The Potterton 3-Way Valve Assembly Without Bypass (Part No. 7224764 / 5132456) is the correct OEM replacement for a reliable, like-for-like repair.

This is a professionally refurbished genuine Potterton 3-way valve assembly. Each unit is completely disassembled with all internal seals, O-rings, and the actuator motor inspected and replaced as required. The assembly is then pressure-tested and electrically function-cycled through multiple CH-to-DHW switching operations under controlled conditions to confirm consistent, reliable performance before dispatch. This is the bypass-free variant — verify your boiler specification before ordering.
