What it is

A 6 bar pressure relief valve (PRV) made for the Alpha CB, CD and Intec boiler range, part number 1.018091. It opens proportionally as system pressure rises, releasing water to stop the pressure reaching a level that could damage the boiler or expansion vessel.

Signs this part needs replacing

  • Water dripping or weeping continuously from the discharge pipe
  • Boiler losing pressure repeatedly and needing regular repressurising
  • Valve fails to reseat fully after opening
  • Visible corrosion, scale or a seized handle on the valve body

Before you order

  • Isolate and safely depressurise the heating system before removal
  • Match the part number 1.018091 stamped on the old valve
  • Have the work carried out by a Gas Safe registered engineer
  • Check the discharge pipe still routes correctly to a safe termination point
