What it is

The Andrews 7709339 is a 28mm pipe assembly that runs from the return isolation valve to the pump on the twin lower heat exchanger. It forms part of the water circuit on Andrews water heaters and allows the return side to be isolated for servicing. The assembly is specific to the twin lower heat exchanger arrangement.

Signs this part needs replacing

  • Weeping or dripping from the isolation valve body or the pipe joints
  • Valve spindle seized or stiff, so the return side cannot be isolated
  • Corrosion, scale or staining on the pipework around the connections
  • Water tracking along the pipe or damp patches beneath the assembly
  • Difficulty restoring flow through the return after isolation

Before you order

  • Confirm your appliance model against the fit list above
  • Check that the pipework on your unit is 28mm
  • Confirm the valve position matches the return-to-pump run on your appliance
