What it is

The 3/4F/F 3 Bar Safety Relief Valve is a pressure relief valve for boiler and heating systems, listed within the Special Offers Altecnic valves and vents range. It discharges water once system pressure reaches its 3 bar set point, protecting the appliance and pipework from over-pressurisation. It is a serviceable safety component rather than a performance part.

Signs this part needs replacing

  • Water drips or runs continuously from the relief valve discharge pipe while the system is cold
  • System pressure will not hold and repeatedly falls after topping up
  • The valve weeps or seeps and fails to reseat cleanly after operating
  • Scale, corrosion or debris is visible around the valve body or seat
  • System pressure continues to rise beyond the 3 bar set point

Before you order

  • Confirm both connections are 3/4 inch female and match the valve being removed
  • Check that 3 bar is the correct relief pressure for the appliance
  • Confirm the discharge pipework is routed safely to a suitable drain point
  • Isolate the appliance and depressurise the system before removal
