What it is

The Vaillant Pressure Safeguard, part number 0020143480, is a pressure relief and safety component used in Vaillant ecoTEC VU GB open-vent boiler installations. It forms part of the appliance's pressure control and safety circuit, protecting the boiler and system from excessive pressure. It is listed by the manufacturer for the VU GB 806/5-5 R2, 1006/5-5 R2 and 1206/5-5 R2 models.

Signs this part needs replacing

  • The boiler locks out or shuts down on a pressure-related fault code.
  • System pressure rises beyond the normal operating range with no other cause found.
  • Visible leakage, weeping or discharge from the pressure safeguard body.
  • The component shows corrosion, scale build-up or mechanical damage.
  • Pressure readings behave erratically during heating and hot water demand.

Before you order

  • Confirm the boiler model and GC number against the appliance data badge.
  • Check the existing component's part number before removal where it is still legible.
  • Verify the fault is traced to the pressure safeguard and not to the expansion vessel, filling loop or system pressure sensor.
  • Confirm the appliance is isolated and depressurised before any work begins.
