What it is

The Sime 6040225 is a 1/2 inch pressure relief valve rated at 3 bar, manufactured by Sime for use in its domestic boiler range. It opens at the set pressure to discharge excess water and protect the heating circuit and its components from over-pressurisation.

Signs this part needs replacing

  • Water continually dripping or running from the pressure relief discharge pipe
  • Boiler pressure dropping and needing frequent topping up
  • System pressure rising above the normal range with no obvious cause
  • Discharge pipe passing water when the system is cold
  • Scale or debris at the valve seat preventing it from sealing

Before you order

  • Confirm the existing valve is rated at 3 bar and has a 1/2 inch connection
  • Check the part number 6040225 against the valve or the manufacturer's parts list
  • Match your boiler model against the fitment list above
  • Isolate the appliance and depressurise the system before removal
