The Professional's Choice for a First-Time Fix

Every heating engineer has been there: a customer calls with that classic boiler fault where the heating fires up when they only want hot water, or the radiators stay stone cold. In the vast majority of cases, the diverter valve is the component that has failed. This hard-working part, often referred to as a three-port valve with bypass, acts as the traffic controller inside the boiler, constantly directing the flow of heated water to either the central heating circuit for the radiators or to the plate heat exchanger for domestic hot water. After years of constant movement and exposure to system water, these valves can begin to stick or fail, leading to the mixed signals that cause frustration for the homeowner and an urgent call-out for you.

This is where fitting a genuine OEM replacement makes all the difference. The Baxi 3 Way Valve Assembly With Bypass 5118381, part number 5118381, is the authentic, manufacturer-approved part, engineered for a perfect fit and flawless operation.

It guarantees the component will integrate seamlessly with the boiler’s electronics and hydraulics, avoiding the compatibility issues, leaks, and premature failures often associated with non-genuine or 'pattern' parts. It’s about fitting with confidence, knowing the part is built to Baxi’s exact specifications for durability and performance. This means fewer callbacks, happier customers, and a job done right the first time.
