What it is

The Ariston 572819 is a 1/2 inch safety valve rated at 6 bar, used on Ariston SO 10R SIN Edition 1 appliances. It relieves excess pressure from the system by opening at its set pressure and discharging through the outlet. It is a service component within the boiler's pressure relief and safety valve group.

Signs this part needs replacing

  • Water weeping or dripping continuously from the valve discharge pipe with the system at normal pressure.
  • The valve fails to reseat and close after it has lifted.
  • System pressure climbs above the normal operating range without the valve relieving.
  • Scale, sludge or debris visible at the valve seat or outlet, preventing a clean seal.
  • Discharge pipework shows staining or corrosion from repeated passing.

Before you order

  • Confirm your appliance model against the fit list above, as compatibility is limited to the listed SO 10R SIN Edition 1 units.
  • Check the existing valve's connection size and pressure rating match 1/2 inch and 6 bar.
  • Inspect the discharge pipework and termination before fitting, as a passing valve often leaves deposits behind.
  • Verify the system is depressurised and isolated before removing the old valve.
