What it is

The Baxi pressure relief valve, part number 248650, is a 3 bar safety valve used on Baxi Maxflow Combi appliances. It is set to open as pressure in the heating circuit rises, discharging water so the system does not malfunction or suffer damage from over-pressurisation. The valve is a serviceable item and is normally reached during routine boiler servicing or when system pressure faults are investigated.

Signs this part needs replacing

  • Water discharging from the relief outlet while the system is cold and at normal pressure
  • System pressure climbing steadily and failing to hold at the correct setting
  • The valve weeping or dripping after it has operated once
  • Boiler locking out or shutting down on an overheat fault
  • Scale or system debris stopping the valve from reseating properly

Before you order

  • Check the GC number on the appliance data badge against the compatibility list before ordering.
  • Confirm the previous part number 247402 if working from an older reference.
  • Inspect the valve seating face and any seal at the outlet, as scale or debris can cause a replacement valve to pass water.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
