What it is
The Halstead 840503 is a diverter valve inner service kit for Halstead gas boilers. The diverter valve directs the boiler's output between domestic hot water and central heating, and this kit services the valve's internal components. It is listed under gas boiler spares for the Halstead ACE, Finest and Wickes combi ranges.
Signs this part needs replacing
- No hot water while the central heating continues to run
- Domestic hot water temperature fluctuating or running cold
- Radiators heating when only hot water is demanded
- Diverter valve sticking, causing delayed or incorrect changeover
- Water weeping from the diverter valve area
