What it is
The Chaffoteaux 61020933 is a pressure relief valve fitted across a range of Chaffoteaux gas boilers, including combi, system and open flue models. It discharges water from the heating circuit when system pressure rises above the valve setting, protecting the boiler and associated components from over-pressurisation. The part supersedes Chaffoteaux code 76584.00.
Signs this part needs replacing
- Water continually dripping or running from the boiler discharge pipe
- System pressure climbing when the boiler heats up, or sitting higher than the normal cold-fill reading
- Boiler losing pressure and needing frequent topping up
- Visible weeping, corrosion or scale staining around the valve body
- Discharge pipe passing water with the system cold and at normal pressure
Before you order
- Match your boiler model and GC number against the fitment list above
- Check the part number on the existing valve; older valves may carry the superseded code 76584.00
- Confirm the appliance variant, as this valve is listed across combi, system and open flue models
- Isolate the appliance and depressurise the system before removal
