What it is

This is a cleanout flange supplied by Hamworthy for use on calorifier vessels. It forms the removable cover over the cleanout or inspection opening, allowing the vessel interior to be accessed for descaling and flushing before the flange is refitted and sealed. The part is identified by Hamworthy part number 181968 and the alternative number 5447200.

Signs this part needs replacing

  • Water weeping or tracking from the cleanout joint, particularly once the vessel is up to temperature
  • Visible corrosion, pitting or distortion on the flange face
  • A flange that will not pull down evenly, or that has been overtightened and deformed
  • Repeated scaling at the opening, suggesting the joint no longer seals correctly
  • Difficulty getting a seal after a descale and flush

Before you order

  • Compare the part number on the old flange with 181968 or 5447200 to confirm you have the correct item
  • Check the calorifier model and serial plate so the appliance can be matched against the compatibility list
  • Inspect the matching gasket or sealing face at the same time, so the joint can be reassembled in one visit
  • Confirm the vessel has been drained, depressurised and allowed to cool before the flange is removed
