What it is

The Potterton 5141439 is a water pressure gauge for Potterton Commercial boilers. It provides a dial reading of system water pressure on the appliance, allowing the engineer to verify operating pressure during servicing and fault finding. It is listed under gas boiler spares in the pressure gauge category.

Signs this part needs replacing

  • The gauge needle sits at zero or fails to move when the system is pressurised
  • The reading disagrees with a known correct pressure elsewhere on the system
  • The dial face is cracked, clouded or has lost its markings
  • The gauge body or its connection weeps water
  • The needle sticks or jumps rather than moving smoothly

Before you order

  • Confirm the appliance model against the fit list above
  • Check the part number on the existing gauge or in the appliance documentation
  • Inspect the gauge connection and surrounding pipework for damage before fitting
  • Verify the fault is the gauge itself and not a system pressure issue
