What it is

The Vaillant 0020143495 is a pressure gauge used on ecoTEC VU gas boilers. It displays the system water pressure on the boiler's pressure gauge dial, allowing the engineer or homeowner to confirm the heating circuit is correctly charged. It is listed under gas boiler spares for the ecoTEC VU range.

Signs this part needs replacing

  • The needle sits at zero or does not move when the system is pressurised.
  • The pressure reading is erratic, sticking or inconsistent with a known-good gauge.
  • The dial face is clouded, cracked or the needle is bent.
  • Water weeps or drips from the gauge body or its connection.
  • The gauge reads a fixed pressure regardless of changes to the filling loop.

Before you order

  • Confirm your boiler model against the fitment list above.
  • Check the GC number on your appliance data badge matches the model listed.
  • Compare the part number on the existing gauge with 0020143495.
  • Check the gauge connection and thread on the boiler before fitting.
