What it is

The Ravenheat 5003621 is a 1 inch central heating return connecting pipe used on Ravenheat RSF 820/20 series gas boilers. It forms the return-side pipework connection, carrying system water back into the boiler circuit. It is supplied as a pipe assembly for replacement on the appliance models listed below.

Signs this part needs replacing

  • Visible corrosion, pitting or scaling on the pipe body or at the connection ends
  • Weeping or dripping from the pipe joints or unions
  • Loss of system pressure with no other obvious source
  • Discolouration or heat damage around the pipe
  • Restricted flow or kettling noise traced to the return connection

Before you order

  • Confirm the boiler model and GC number against the fitment list above
  • Check the pipe connection size and orientation match the failed part
  • Inspect the surrounding pipework and seals, as these may also need attention
  • Isolate and drain the boiler before removal
