What it is
The Alpha drain pipe safety valve is a pipe tundish adapter for Alpha CD series LPG boilers. It forms part of the safety valve discharge pipework, connecting the valve outlet to the drain via a tundish. Alpha part number 1.011654.
Signs this part needs replacing
- Water leaking or dripping from the tundish or pipework
- Visible corrosion, cracking or distortion of the adapter
- Scale or debris build-up restricting flow through the tundish
- Water overflowing from the tundish rather than draining away
- Discolouration or staining around the safety valve discharge
Before you order
- Confirm your boiler model matches one of the LPG variants listed
- Check the existing part number on the component or in the manufacturer's parts list
- Verify the appliance is the LPG version, as the fitment list covers LPG models only
- Inspect the surrounding pipework and safety valve for related faults
