What it is
The Vokera by-pass casing, part number 10024641, is a black valve body used in the hydraulic circuit of Vokera gas boilers. It forms the housing for the by-pass arrangement that keeps water moving through the appliance when system demand falls away. It is listed against the Compact, Linea, Excel, Evolve and Easi-Heat Plus families.
Signs this part needs replacing
- System pressure rising or fluctuating as heating demand changes
- Overheat lockout or high-limit thermostat trips
- Kettling or rushing water noise from the boiler
- Water weeping or staining around the by-pass casing
- Fault codes relating to flow or temperature differential
Before you order
- Confirm your boiler model and GC number against the manufacturer's parts list
- Check the existing casing is marked with part number 10024641
- Confirm whether the appliance is natural gas or LPG, as variants differ
- Inspect the by-pass assembly and seals for damage before refitting
