What it is

The Baxi 7810671 is a safety valve supplied with its O-ring already fitted. It sits in the pressure relief circuit of Baxi Combi 2 and System 2 appliances, opening to discharge water when system pressure rises above the valve's set point.

Signs this part needs replacing

  • System pressure climbs above the normal operating range and continues to rise
  • Water discharging from the valve outlet or discharge pipe while the boiler is running
  • The valve weeps or drips once the system has cooled
  • The valve fails to reseat after operating, so the system will not hold pressure
  • Scale, corrosion or damage visible around the valve seat or O-ring

Before you order

  • Confirm your appliance model and GC number against the fitment list
  • Check the valve connection and orientation on your appliance before removal
  • Inspect the O-ring seating face for damage before fitting the new valve
  • Isolate and depressurise the system before starting work
