What it is
The expansion vessel pipe is a manufacturer-supplied pipe assembly for Alpha gas boilers. It connects the expansion vessel to the boiler's heating circuit, allowing the vessel to absorb pressure changes as the system water heats and expands. This part is listed for the Alpha 500 E.
Signs this part needs replacing
- Water weeping or dripping from the pipe or its connections
- Corrosion, pitting or scale build-up on the pipe surface
- Visible cracking, kinking or deformation of the pipe
- Boiler repeatedly losing system pressure with no other obvious cause
- Discolouration or staining around the expansion vessel connection
Before you order
- Confirm your boiler is an Alpha 500 E and check the GC number against the data plate
- Compare the part number 6.5622900 with the marking on the existing pipe
- Inspect the pipe connections and seals for damage before fitting
- Check that the expansion vessel itself is sound, as pressure faults can originate there
