What it is
The header for the heat exchanger is a manufacturer-supplied component for Andrews water heaters. It forms the end connection of the heat exchanger assembly, directing water flow through the exchanger body. This is the revised (REV) version of the part, listed under manufacturer part number 7871631.
Signs this part needs replacing
- Water weeping or dripping from the header joint or its sealing faces
- Visible corrosion, pitting or scale build-up on the header body
- Reduced hot water output or unstable temperatures linked to restricted flow through the exchanger
- Loss of system pressure with no other obvious source of leakage
- Distortion or cracking around the header connections
Before you order
- Confirm your appliance model and serial number against the manufacturer's parts list
- Check that the existing header is the revised (REV) type before ordering
- Verify the part number 7871631 matches the component being replaced
- Inspect the mating seals and gaskets, as these are not supplied with the header
