What it is

The Ideal 176637 is a lower flow pipe used in Ideal Logic System gas boilers. It forms part of the boiler's pipe assembly, carrying water through the lower section of the appliance. This part is identified by the ZP and AAJ prefixes.

Signs this part needs replacing

  • Visible leaks or weeping joints around the lower flow pipe
  • Corrosion, pitting or surface discolouration on the pipe
  • Scale or debris build-up restricting flow through the pipe
  • Boiler noise such as kettling or banging linked to restricted flow
  • Loss of system pressure that cannot be traced to another component

Before you order

  • Confirm your boiler model and GC number against the list above
  • Check the appliance prefix is ZP or AAJ
  • Verify the part number 176637 matches the pipe currently fitted
  • Inspect the surrounding pipework for related damage before fitting
