What it is

The Baxi 7875841 is a cable bridge for the pressure relief valve fitted to Baxi Aquaheat Hi and HWI appliances. It connects the pressure relief valve to the appliance wiring so the valve operates as part of the boiler's pressure control circuit. It is supplied as a cable assembly for the pressure relief valve connection.

Signs this part needs replacing

  • The pressure relief valve does not open or discharge when system pressure rises
  • Water weeping or discharging continuously from the pressure relief valve outlet
  • The boiler loses pressure repeatedly with no visible leak elsewhere on the system
  • Visible damage, chafing or corrosion on the cable or its connectors
  • A fault or lockout condition linked to pressure relief valve operation

Before you order

  • Confirm the appliance model matches one of the fitments listed above
  • Inspect the existing cable and connectors to confirm the fault lies with the cable rather than the valve body
  • Note the appliance model and part number 7875841 before ordering
